Pneumatic Connectors, Fittings & Hose
We provide an extensive range of connectors, fittings, and hoses. Partnering with leading brand SMC, we offer hundreds of push-in, tube-to-tube, and threaded-to-tube fittings, along with a wide variety of couplings and adapters designed to suit nearly every pneumatic application.
What are pneumatic fittings used for?
Pneumatic fittings are essential components used to join lengths of tubing, pipes, and hoses within pressurized pneumatic systems. Compared to hydraulic fittings, they generally feature tighter seals and operate under lower pressure requirements. These fittings are commonly found in industrial robotics on production lines, as well as everyday devices like vacuum cleaners and tire pressure gauges.
Types of pneumatic fittings
Pneumatic fittings are mainly manufactured from three materials: plastic, stainless steel, and polymer. Stainless steel and polymer fittings are preferred in the food and beverage sector due to strict hygiene standards, but all three materials are suitable for a wide variety of other applications.
How do pneumatic fittings work?
Pneumatic fittings function through various connection methods and come in multiple configurations:
- Threaded-to-tube adaptors and fittings: These feature a quick-fit push-in connection on one end and a tapered or parallel threaded connection on the other. They come in multiple tube and thread sizes and are also available as elbow and Y adaptors.
- Tube-to-tube adaptors and fittings: Designed with quick-fit push-in connections, these fittings connect tubes of various sizes and can also adapt from one tube size to another.
- Threaded adaptors and fittings: Equipped with tapered or parallel threads on all connections, these fittings come in forms such as bulkhead adaptors, threaded bolts, elbows, crosses, and manifold fittings.
How to measure pneumatic fittings
To determine the correct thread size for a pipe fitting, measure the inner diameter of the threaded hole where the fitting will connect or the outer diameter of the threaded section on your existing fitting.
