Tubing Cap KQ2C


The KQ2C one-touch tube caps are used to plug unused nylon and polyurethane tubes. The special profile design of these fittings provides positive sealing under pressure. When the tubing cap is removed from the tube, the chuck and collet are released, thus preventing them from biting into the tube excessively.

The special profile design of the seal provides positive sealing under pressure without reduced flow
Release button allows tube to be removed easily without damage
