Quick answer: Write a pneumatic fittings RFQ as a short spec sheet: name the coupler profile and connection standard (American/ARO, Euro 7.2/10.5/13.2 mm, or ISO 6150B/Nitto), the thread form and size (BSP or NPT), the material (brass, steel or stainless SS304/316), and the quantity per item. Attach a drawing for any custom or OEM part. A clear RFQ lets a manufacturer return an accurate quote fast, confirm the 1,000-piece minimum and 3-5 day sample lead, and flag any profile or thread mismatch before tooling starts.
Sourcing pneumatic couplers, fittings and air-preparation parts from a factory should start with one document: the request for quotation, or RFQ. A good RFQ is not a long email - it is a short, structured spec that tells the supplier exactly what you need so the quote comes back complete and comparable. If you have not yet chosen who to buy from, our guide to choosing a pneumatic fittings supplier covers the seven questions to ask first, and our MOQ, lead-time and factory-audit guide explains the commercial terms you will negotiate. This article focuses on the document itself: what to put in it, a ready-to-copy template, and what a capable manufacturer should send back.
What a pneumatic RFQ should contain
A complete RFQ removes guesswork. Cover these points for every item on your list so the supplier quotes the right part the first time:
Coupler profile and connection standard
Quick couplers are not interchangeable by size alone. State the profile family you need - American/ARO, Euro (7.2, 10.5 or 13.2 mm), or ISO 6150B/Nitto - and whether you need a standard or high-flow series. If you are unsure which profile your existing tools use, our quick coupler profiles guide explains how to identify them and avoid mismatched seals. Browse the quick couplers range to see the profiles and materials side by side before you write the line item.
Thread form and size
The two common thread standards are BSP (55 degree, common in Europe and Asia) and NPT (60 degree, common in North America), and they do not mate. Specify the thread form, diameter and any taper in your RFQ, and confirm it matches the equipment you will connect to. Our BSP vs NPT thread guide shows how to identify them by angle and threads-per-inch so you can state the right one with confidence.
Material, plating and media
Couplers and fittings come in brass, steel and stainless (SS304/316). State the body material and any plating, and note the medium (compressed air, water, oil or inert gas) and the pressure and temperature range. For corrosive or precision environments, stainless fittings are the usual choice; our stainless vs brass fittings comparison walks through where each material belongs. The stainless steel fittings line and the air-line and brass fittings line cover the standard options.
Quantity, packaging and branding
Give the per-item quantity and total, the target unit-price bracket if you have one, and any packaging or barcode needs. Because the standard minimum order is 1,000 pieces per item, state your expected annual volume so the supplier can suggest the right batch size. Mention branding, labels and carton marks if you are building a private-label range.
A simple RFQ template
Use the table below as a fill-in form - one row per item keeps the quote comparable across suppliers. Copy it into your email or RFQ sheet:
| Field | What to write | Example |
|---|---|---|
| Item / part name | Coupler, plug, tee, nipple, manifold | Euro 7.2 mm female coupler |
| Profile / standard | Family + series | Euro 7.2 mm, high-flow |
| Thread | Form + size + taper | BSP 1/4 inch parallel |
| Material | Body + plating | Brass, nickel-plated |
| Medium / pressure | Air, water, oil + max bar | Compressed air, 10 bar |
| Quantity | Per item + total | 5,000 pcs |
| Drawing / custom | Attach or describe | OEM body with logo |
| Packaging | Bag, box, carton, barcode | 50/inner, 500/carton |
| Target price | If known | FOB Ningbo, budget only |
| Delivery window | Needed-by date | 2026 Q2 |
What a manufacturer should send back
A complete quotation answers your RFQ point by point. Expect the following in a professional reply:
- A per-item price against each line, with the Incoterm and currency stated so quotes from different suppliers are comparable.
- Confirmation of the 1,000-piece minimum order per item and the production lead time for your specific mix - ask for this explicitly if it is missing.
- Sample availability. At JIAJIE, free samples can normally be prepared in 3-5 days so you can check fit, seal and finish before committing to a run.
- Drawing review for any OEM or custom part, since the workshop works from customer drawings for OEM/ODM programs.
- A mismatch note on any profile, thread or material you specified that conflicts with what they make - raised before tooling rather than after.
RFQ mistakes that slow the quote down
A few habits cause most delays. Avoid them and your quote comes back in days, not weeks:
- Sending only a photo with no dimensions. A drawing or the five key specs above is far faster to quote than a picture to measure.
- Mixing thread standards without saying which. Always name BSP or NPT explicitly; do not assume.
- Forgetting the profile family on couplers. A bare 1/4 inch coupler reference is not enough - state American/ARO, Euro or ISO 6150B.
- Listing a quantity below the minimum without asking about a starter batch for a new range.
- Omitting the medium and pressure, which change seal material and body choices.
Sourcing pneumatic couplers and fittings from JIAJIE
JIAJIE Pneumatic is the export brand of a Ningbo, China workshop established in 2005 with around 15 people, making pneumatic quick couplers, air-line fittings, stainless precision fittings, air-preparation units, airbrushes, mini compressors and pneumatic power tools. The workshop offers OEM/ODM and drawing-based machining, so coupler profile, thread, material, branding and packaging can be matched to your range rather than forced into ours. The standard minimum order is 1,000 pieces per item, and free samples can be prepared in 3-5 days. Sitting roughly 40 km from the Port of Ningbo, export shipping is straightforward. To start an RFQ, contact David Liu at DAVID@nbliunian.com or on WhatsApp +86 183 6130 1735, and include the spec points above so the quote comes back complete.
Frequently asked questions
What should I include in an RFQ for pneumatic fittings?
Include the coupler profile and connection standard (American/ARO, Euro 7.2/10.5/13.2 mm, or ISO 6150B/Nitto), the thread form and size (BSP or NPT), the body material and plating (brass, steel or stainless SS304/316), the medium, pressure and temperature, and the quantity per item with packaging and branding notes. Attach a drawing for any custom or OEM part. State these five key specs - profile, thread, material, quantity and drawing - on every line item so the quote is complete and comparable.
BSP or NPT - which thread should I specify in an RFQ?
It depends on the equipment you will connect to. BSP is a 55-degree thread common in Europe and Asia; NPT is a 60-degree thread common in North America. They do not mate, so name the form explicitly and give the diameter and any taper. If you are unsure, our BSP vs NPT thread guide explains how to identify each by angle and threads-per-inch, and you can measure a sample fitting before writing the RFQ.
What is the minimum order quantity for pneumatic couplers and fittings?
The standard minimum order is 1,000 pieces per item at JIAJIE. State your expected annual volume in the RFQ so the supplier can suggest an efficient batch size. If you are launching a new range and need less than the minimum for a first run, ask whether a starter batch is possible rather than assuming it is unavailable.
Can I get samples before placing a production order?
Yes. At JIAJIE, free samples can normally be prepared in 3-5 days so you can verify fit, seal, thread and finish on your own equipment before committing to a production run. Include the exact specifications in the RFQ - profile, thread, material and quantity - so the samples match what you intend to order.
Do you support OEM/ODM and custom pneumatic fittings?
Yes. JIAJIE offers OEM/ODM and drawing-based machining across its coupler, fitting and air-preparation lines, so profile, thread, material, branding and packaging can be matched to your range. Attach a drawing or a detailed specification in the RFQ so the workshop can review the part and quote it accurately before any tooling begins.
