Bulkhead Union KQ2E (Interchangeable With KJ), One-Touch Fitting KQ2 Series
Product Description
One-touch fitting used to connect tubing through a panel, etc.
[Features]
· Compact, lightweight type with improved tube insertion and removal.
· Suitable for use with nylon and urethane. The chuck provides secure retention and the collet increases the holding force on the tube.
· Can be used for a wide range of pressures from a low vacuum up to a pressure of 1 MPa.
· The use of a special profile ensures sealing and reduces resistance when the tube is inserted.
· Piping workability can be improved by changing to a face seal structure.
· When the fitting is removed from the tube, the chuck and collet are released, thus preventing them from biting into the tube excessively.
[Applications]
Use to connect two pieces of tubing through a panel, etc.
