Hy-Lok Q Series quick-couplers are used for quick production of a reliable, gas-tight connection. The advantages compared with a conventional screw connector are the quick and simple use without twisting and screwing and the avoidance of damage to threads caused by over-tightening. With Hy-Lok quick-couplers, the medium loss during disconnection and the air trapping during connection is minimised.
Hy-Lok Q Series quick-couplers with full passage minimise machine stoppages, can be operated without tools and are available in a wide range of versions, connections, body fittings and protection devices.
Temperature dimensioning: -23°C to 204°C (-10°F to 400°F) with FKM O-ring
Fields of application:
Hy-Lok Q Series quick-couplers are available with single-end (SESO) and double-end (DESO) shut-off. Encoded quick-couplers help to prevent accidents. They are interchangeable with comparable Swagelok, Parker, Hoke or TOMCO components.
