SMC KQ2 Series Straight Threaded Adaptor, R 1/8 Male to Push In 3/16 in, Threaded-to-Tube Connection Style

The KQ2 one-touch male straight adaptors are used to pipe in the same direction from a female thread and are suitable for use with nylon and polyurethane tubes. The special profile design of these fittings provides positive sealing under pressure without reducing the flow. When the adaptor is removed from the tube, the chuck and collet are released, thus preventing them from biting into the tube excessively.

The Uni thread is suitable for common applications for Rc, G, NPT and NPTF.
