Couplers

Cla-Val couplers are designed to provide safe and accurate connection during aircraft refueling.

The 353GF EI 1584 3rd Edition Pressure Coupler connects to a hydrant pit valve or hydrant pit adapter to allow pressurized fuel to flow from an underground pipeline and into the receiving aircraft.  It incorporates a Deadman operated, direct acting pressure regulator that protects the receiving aircraft from excess pressure and from damage caused by surges.

The 351GF-15 Hydrant Coupler connects to any EI-style hydrant pit adapter or hydrant pit valve to allow pressurized delivery of fuel to aircraft. Constructed of high-strength stainless steel and aluminum, the Hydrant Coupler conforms to EI Bulletin 1584.

The 346GF Emergency Breakaway Coupler cleanly comes apart and closes both separated halves when an excessive axial load is applied. This makes it possible for a pilot to safely drive/fly away from the refueling facility in case of emergency, virtually eliminates fuel loss and protects the environment in the event of a breakaway.
