SMC one-touch tube fittings come in metric and inch size pneumatic fittings and are available in a wide variety of sizes, body styles and thread types.  The specially designed packing provides positive sealing under pressure without the reduced flow common with compression fittings.  SMC offers one-touch tube fittings in several special environments such as anti-static, flame resistant, clean room, DOT, and food service fittings.

The 25A- series variations are designed using material compatible with secondary battery applications and are able to be used in low dew point environments.  The variations eliminate copper (Cu) and zinc (Zn) material where possible, making them compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types.
