Products · Pneumatic Fittings

Fittings to match every tube we make.

Push-in connectors, flow-control valves, 316L stainless fittings and quick couplers — coded to the same Ø4–Ø16 mm range as our tubing. Pair tube and fittings in a single order, from one supplier. Full model and dimension tables are available on request; tell us the tube size and thread and we'll confirm the exact code.

Tube OD → fitting code

Every fitting is coded to the tube outer diameter, so tubing and connectors always match. The same code runs across all families — push-in, valves, stainless and couplers.

Product families

Six families cover the great majority of pneumatic connection needs. Chip colour marks the family; full dimension tables are available on request.

One-Touch Push-In Fittings
Insert the tube and it locks; press the collet to release. Direction stays adjustable after fitting. Nickel-plated brass body with NBR seals — the everyday workhorse for air lines.

Mini Fittings
About 40% smaller than standard, with an oval sleeve that's easy to push and pull in tight spaces. Built for small equipment and dense tube layouts, Ø3–Ø6 mm.
Compact · M3/M5/M6 · R1/8

Flow Control & Valves
Speed controllers to tune cylinder speed, check valves for one-way flow, and hand valves that shut off air and release residual pressure for safe maintenance.

316L Stainless Steel Fittings
SUS316L body with FKM seals — oil-free and corrosion-resistant for food, chemical and medical lines. Suited to air, water and steam, to roughly 1.2 MPa and 120 °C.

All-Brass Push-In Fittings
A full-brass body for higher durability and temperature tolerance where a resin body isn't enough. Available with G and R (PT) threads across the size range.

Why source fittings with your tubing

01

One purchase order

Tube and matching connectors ship together from one supplier — fewer POs, one packing list, one point of contact.

02

Guaranteed size match

Fitting codes follow the tube OD, so Ø8 tube meets an "08" fitting every time. No mismatched orders.

03

Full thread coverage

Metric M, taper R(PT), parallel G and NPT — matched to the equipment you're plumbing into.

04

Material to suit the line

Nickel-plated brass for general air, full brass for heat, and 316L stainless for food, chemical and washdown.

Also available: transition fittings (brass hex, nipples, tees), bulkhead and manifold blocks, push-on (barb) fittings, and full-copper PUSH-in series. Fittings pair with our PU, PA, PE and TPEE tubing — tell us the application and tube size and we'll put together a matched tubing-and-fittings quote.

Pair your tubing with matching fittings.

Send your tube sizes and thread type and we'll quote tube and fittings together.
