Hydrant Coupler

Hydrant Coupler: 


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

Military Aircraft Underwing Refuelling Nozzle:


The Cla-Val Model 341GF-D3 Nozzle is an “underwing” refuelling nozzle for pressure fuel servicing of a wide range of military aircraft and for bottom loading of tank trucks. The Model 341GF-D3, fitted with the D-3 Swivel Inlet, replaces both the D-1 and D-2 nozzles. The 341GF-D-3 Nozzle is equipped with a unique inlet assembly that adjusts to connect to adapters located on the fuselage and/or under wing. By twisting the inlet assembly, it quickly and easily changes from 0° to 45° configurations, or any configuration in between.
