Bulkhead Union KQ2E


The KQ2E one-touch bulkhead unions are used to connect tubes through a panel and are suitable for use with nylon and polyurethane tubes. The special profile design of these bulkhead unions provide positive sealing under pressure without reducing the flow. When the connector is removed from the tube, the chuck and collet are released, thus preventing them from biting into the tube excessively.
