1 adapter (2 pieces)

Adapter for direct refueling G 3/4 UNF at 21.8.

G 3/4 UNF connections are usually on refillable gas cylinders with 80% fill stop and fuel gauge.

The adapter is screwed onto the filling hose connection of the gas bottle and, thanks to its W21.8mm outlet thread, allows Europe-wide direct refueling at filling stations with the help of the respective W21.8 tank adapter
