Compact Plastic-Body Push-In Fittings for Everyday Pneumatic Automation
Plastic-body push-to-connect fittings provide a lightweight, compact way to connect pneumatic tubing to valves, cylinders and other compressed-air equipment. The source range uses nickel-plated brass threaded sections with a plastic fitting body.
NPT and BSPT tapered threads are supplied with pre-applied thread sealant for faster assembly, while universal tri-thread and smaller parallel-thread versions use an NBR O-ring seal.

Are the threaded sections metal?
Yes. The source description states that the fitting threads are nickel-plated brass.
Do NPT and BSPT versions include thread sealant?
Yes. The source description says tapered NPT and BSPT threads have pre-coated thread sealant.
How do parallel-thread versions seal?
The source description states that universal tri-thread and small parallel threads use an NBR O-ring seal.
What is the listed working pressure?
0–150 psi(g) / 10 bar(g).
Can they be used for vacuum?
The source specification lists vacuum duty to 29.5 inHg / 14 mbar(a).
Why choose plastic-body fittings?
They are compact, lightweight and well suited to general industrial pneumatic automation.
