KQ2 one-touch, metric and inch size fittings 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. The KQ2 release collar releases both the chuck and collet to provide a low disconnection force for easy removal of the tubing. KQ2 fittings are available to order in multiples of 10.
