SMC® KQ2H04-M3G One-Touch Pneumatic Connector With Gasket Seal, Connector, 4 mm x M3x0.5, Tube x MNPT End Style, Brass

KQ2 one-touch, metric and inch size fittings are available in a wide variety of sizes, body styles and thread types. The use of a special profile seal allows the KQ2 to be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa. The KQ2 release collar releases both the chuck and collet to provide a low disconnection force for easy removal of the tubing.
