Interchangeable with Flight Refueling Couplers

Made entirely of stainless steel, these couplers are fully interchangeable with Flight Refueling models, as well as those available from A. Searle & Co.. Because we make the caps of aluminum, there is no possibility of thread galling as in other brands when the coupler is also aluminum. We used the Gammon tapered gland O-ring seal principle that has proven to be astonishingly reliable for the last 50 years in the Jet Test QD®.

In addition to the two basic models, we also offer each one with either BSP or NPT threads for installation on fueling nozzles. Refer to the chart below.
