To request an accurate armored flexible conduit quote, send the conduit construction, inside and outside diameters, operating environment, fitting requirements, quantity by size, packaging requirements, and delivery destination. Attach a drawing, datasheet, or sample reference where possible, and identify any specifications that still need technical confirmation.

A request such as “Please quote 5,000 meters of 20 mm armored conduit” leaves several questions unanswered. Does 20 mm refer to the inside diameter, outside diameter, or a nominal size? Is the conduit bare metal or jacketed? Are connectors included? Will it remain stationary or move with the equipment?

For equipment manufacturers, electrical contractors, and distributors, these details determine whether the quotation covers a usable product or simply an apparently attractive price. This guide explains what to include in your request for quotation, how to handle missing information, and how to compare offers before placing a bulk order.

Armored Flexible Conduit RFQ Checklist

Use the following checklist before sending your inquiry. Mark unknown items as “supplier recommendation required” instead of leaving them blank.

Keep technical requirements and commercial requirements in the same RFQ package. Sending them separately increases the chance that a revised specification will not reach the person preparing the price.

1. Identify the Conduit Construction You Need

Start with a product description that goes beyond “armored hose.” For an electrical cable protection inquiry, explicitly state that you need flexible conduit for routing electrical cables. This helps avoid confusion with fluid hoses or armored cable assemblies.

When reviewing armored flexible conduits, reference the listed product series where available. The range includes JS galvanized metal hose and JSB and JSP plastic-covered metal conduit listings. A series reference is a useful starting point, but the supplier should still confirm the exact construction and dimensions offered.

Specify the metal core and outer covering separately

If the design already specifies a core material, provide its designation. If it specifies a jacket, identify the required material, color, and any environmental performance requirements. Avoid requesting only “heavy duty” or “premium quality”; these descriptions do not establish a measurable purchase specification.

Where the material remains undecided, explain the service conditions and request a recommended construction. Ask the supplier to identify the core material, jacket material, and any limitations in its proposal. This turns an assumption into something your engineering team can review.

For replacement purchases, include the current part number and datasheet, but state whether you require an exact replacement or will consider an alternative. An alternative should be accompanied by a comparison of dimensions, materials, fittings, and documented performance.

2. Define the Size Without Relying on Nominal Diameter Alone

An armored flexible conduit quotation should identify the dimensional basis clearly. Write “minimum usable inside diameter” when cable clearance is the concern, and specify a maximum outside diameter when clamps, brackets, or restricted routing spaces control the design.

A nominal size should be accompanied by the supplier’s dimensional table. Do not assume that two products carrying the same nominal label have identical internal clearance or accept the same connectors.

Send cable details when the conduit size is not finalized

Provide the number of cables, their individual outside diameters, and their datasheets. Include the dimensions of any preinstalled plugs or connectors that must pass through the conduit. A cable bundle may fit while its terminated connector does not.

Ask your engineering team to confirm the applicable cable fill and installation requirements. Do not use one generic fill percentage for every installation. The proposed conduit and the cable arrangement should be reviewed together, including pulling access and any future cable additions.

Include the routing constraints

Attach a sketch showing the route length, bends, connection points, and available clearance. Identify the tightest required bend and ask for the minimum bend radius of the proposed conduit in the intended service condition.

The cable’s own bend limit also needs to be respected. A conduit that can bend around a corner does not establish that the cables inside can safely follow the same path.

For replacement parts, provide photographs with a scale and measurements from an undamaged sample. Treat photographs as supporting evidence; they cannot reliably establish material grade, dimensional tolerances, or performance ratings.

3. Describe the Actual Operating Environment

Terms such as “industrial use” and “outdoor application” are too broad for a reliable material recommendation. A sheltered control cabinet connection and a machine exposed to cleaning chemicals may require very different specifications.

Temperature and exposure

Report the expected minimum and maximum operating temperatures. Distinguish continuous exposure from short peaks, and include installation temperature if the conduit will be handled or bent in cold conditions.

Identify exposure to rain, condensation, oil splash, coolant, cleaning agents, sunlight, or salt spray. For chemicals, provide the substance name, concentration, exposure temperature, and whether contact is occasional or continuous. If the process changes seasonally, describe the most demanding condition.

This information gives the supplier a basis for reviewing the complete material combination, including the jacket and connector seals. “Chemical resistant” without a named chemical and exposure condition is not enough to approve a product.

Fixed routing, vibration, or repeated movement

State whether the conduit will remain fixed after installation, experience vibration, move occasionally for maintenance, or bend repeatedly during operation.

For repeated movement, include the motion path, bend radius, travel, cycle frequency, expected life, and any twisting. Ask the supplier for evidence relevant to that motion. Do not treat general flexibility as confirmation of continuous flexing capability.

Describe external mechanical risks as well. If the route may be struck, rubbed against a machine frame, or compressed, identify the location and the project’s required test or acceptance criterion. This is more useful than asking for the “strongest available conduit.”

4. Quote the Conduit and Its Connections Together

A low conduit price has limited value if compatible fittings are missing from the quotation. Include the connection requirements in the initial RFQ, even if you plan to purchase the fittings separately.

Specify the conduit connection at one end of the fitting and the enclosure connection at the other. These are separate interfaces. A thread description alone does not identify which conduit the fitting can accept.

For conduit connectors and fittings, identify whether you need straight, 45-degree, or 90-degree connections. Include the enclosure thread designation, pitch where applicable, available thread engagement, and panel thickness or mounting drawing.

Ask the supplier to itemize locknuts, sealing washers, inserts, and other required accessories. Confirm which components are included in the quoted unit price and which must be ordered separately.

Make protection requirements specific to the assembled system

If the project requires an ingress protection rating, request confirmation for the proposed conduit, fitting, seal, and enclosure interface under the specified installation conditions. Do not infer the performance of the entire assembly from a general website statement or a rating attached to another product.

Where electrical continuity, bonding, or electromagnetic shielding is required, identify the project requirement and request relevant supporting information. A metal construction alone should not be used as proof that the proposed assembly meets an electrical performance requirement.

5. Break Down Quantity, Length, and Packaging

Provide the purchase quantity for each size and construction. Separate the immediate order from estimated future demand, and label forecasts clearly so they are not mistaken for committed quantities.

An effective quantity schedule might distinguish sample requirements, an initial production batch, and expected repeat orders. Ask the supplier to state the minimum order quantity and price breaks for each item, including any separate minimums for custom colors or packaging.

Explain how the conduit will be supplied

State whether you need coils, reels, loose cut lengths, or complete assemblies. For coils, specify the preferred continuous length and whether multiple pieces within a coil are prohibited. For cut lengths, provide the quantity per length, allowable tolerance, and how the length should be measured.

For assemblies, clarify whether the dimension refers to the conduit alone or the completed assembly, and define the measurement endpoints. If two angled fittings must face a particular direction, include their orientation on the drawing.

Packaging should support the receiving and production process. Specify item codes, batch identification, carton quantity, label language, and any barcode requirements. Buyers considering custom assembly and kitting should provide a bill of materials for each kit and request confirmation of the available scope before comparing prices.

6. Identify Required Documents and Sample Acceptance Checks

Send the customer specification or approved purchasing standard with the RFQ. Highlight mandatory requirements and distinguish them from preferences. Ask the supplier to list any deviations explicitly rather than replying with a general statement of compliance.

Request documents applicable to the exact proposed product and size range. Depending on the project, these may include a dimensional drawing, material declaration, inspection report, test report, or product certification. A company-level quality document does not replace evidence for a specific product requirement.

Where a particular approval is mandatory, provide its exact designation and ask the supplier to confirm coverage. Avoid treating broad claims about a manufacturer’s product portfolio as confirmation that every conduit and fitting combination carries the same approval.

Agree on sample approval before production

Define what the sample evaluation must resolve: cable insertion, connector engagement, mounting clearance, routing, dimensional conformity, or a specified performance test. Request samples of the proposed conduit and matching fittings together where compatibility is critical.

Record the approved part number, drawing revision, materials, and sample reference. If the sample requires a change, update the specification before releasing the bulk order. Approval based only on appearance leaves important differences unresolved.

Also ask how substitutions or material changes will be communicated for repeat orders. Purchasing consistency depends on maintaining the approved specification, not merely repeating the original product description.

7. State Delivery and Commercial Requirements Clearly

Include the delivery country, city or port, and required arrival date. Distinguish the date the goods must leave the factory from the date they must reach your facility.

Ask the supplier to separate sample preparation, production, and estimated transport time. Where drawings or samples require approval, request confirmation of the milestone that starts the production lead time.

For an international quotation, specify the agreed shipping term and named location. Request the currency, payment terms, quotation validity, estimated packed weight, and packing dimensions. Identify whether freight, insurance, customs handling, duties, and taxes are included or excluded so your purchasing team can calculate comparable totals.

If timing is critical, ask whether partial shipments are available and what additional costs they would create. A lower unit price may not offset the operational cost of receiving all items after the production deadline.

A Practical Armored Flexible Conduit RFQ Template

Copy the following structure into your inquiry. Replace each bracketed field and attach the referenced files. If a requirement is unresolved, mark it for review.

Ask for alternative products to appear as separate quotation lines. Each alternative should explain what changes and why it is proposed. This keeps a lower-cost option from being mistaken for full compliance with the original specification.

How to Compare the Quotations You Receive

Compare technical compliance before comparing unit price. Match each offer against the same RFQ revision and verify that dimensions, construction, fittings, length format, and documentation are included on the same basis.

For example, a per-meter quotation for bare conduit and a per-meter quotation for jacketed conduit with connectors are different offers. Similarly, a coil price may look attractive until cutting waste, missing accessories, or additional inspection costs are included.

Build a comparison around the total cost of an acceptable delivered order: conduit, fittings, preparation, packaging, required documentation or testing, and the agreed logistics scope. Keep unresolved requirements visible instead of scoring them as compliant.

Before issuing the purchase order, obtain written clarification of assumptions and deviations. Reference the approved drawing and quotation revision in the order so the supplier, purchasing team, and incoming inspection team work from the same specification.

Frequently Asked Questions

Can I request a quote without a technical drawing?

Yes. Send the application, measured dimensions, cable details, quantities, and clear photographs of the installation or existing part. Ask the supplier to identify missing information and provide a proposed specification. Treat an early price as preliminary until the technical details are agreed.

Is a physical sample enough for an exact replacement?

A sample helps establish fit and construction, but it may not establish the original material specification or performance requirements. Include the operating environment and acceptance criteria, and ask the supplier to document any differences in the proposed replacement.

Should I request fittings in the same inquiry?

Yes, particularly when the conduit series or enclosure interface is changing. Request a compatible combination and an itemized accessory list. If you will retain existing fittings, provide their drawings or samples and ask for compatibility confirmation.

What if I need pricing before the specification is finalized?

Request a budgetary quotation that lists every assumption. Identify which requirements are fixed and which remain open, then request an updated quotation after engineering review. This allows early budgeting without treating an unverified configuration as production-ready.
