Backed by 40 years of successful performance all over the world, the Jet Test QD® is a proven concept in Quick Disconnect Couplers for performing tests for dirt, water, and pressure regulation during the refueling of jet aircraft.

The Jet Test QD® is so small that it can be installed permanently on the underwing fuel nozzle. Prior to the introduction of this product, a pressure or contamination test at the nozzle could not be performed without considerable fuel spillage while a connection was fabricated at the plugged port.

The exposed portion of the Jet Test QD® coupler is no larger than a standard hex head pipe plug, yet it contains an inner or primary seal as well as an outer secondary seal which is created by the dust plug.
