Pneumatic fittings are parts used to connect sections of pipe, tube, and hose in pneumatic (pressurized gas) systems. Compared to hydraulic fittings, pneumatic fittings are typically characterized by tighter seals and lower pressure requirements. They are frequently used in pneumatic logic control systems and instrumentation.
This is 6mm PU6 Union Straight Pneumatic Fitting which is widely used in pneumatic circuit. Both end fitting is push-to-connect tube (6mm) connection. The hose body is Acetal & Brass Nickel Plated Finish Resin provides very strong material for high pressure up to 1Mpa.
