The compact and lightweight KQ2 one-touch has metric- and inch-size fittings that are available in a wide variety of sizes, body styles and thread types. 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 collar is designed to release both the chuck and collet and provide a low disconnection force for easy removal of the tubing without damage. They accept FEP, PFA, nylon, soft nylon and polyurethane tubes.
