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. Tube-to-tube fitting 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 Maximum operating pressure 10 bar Maximum vacuum operating pressure -100kPa Proof pressure 3MPa Ambient and fluid temperature -5 to +60°C (water 0 to 40°C) Note Models with a -X2 suffix in the Mfr Part No. are copper-free (electroless nickel plated).
