The SMC KQ2 one touch fittings are applicable for both vacuum and positive pressure applications. The specially designed packing provides positive sealing under pressure without the reduced flow common with compression fittings. The KQ2 release collar releases both the chuck and collet to provide a low disconnection force for easy removal of the tubing.

Accepts nylon and urethane tubes
Maximum vacuum pressure of 1.0MPa
Compact and lightweight
RoHS compliant
