Radium 8An Dry Break 27Mm Fitting Inner WRX11X it inherently suffers from fuelWhen separating two hoses, dry break fittings permit a leak free disengagement while retaining pressure. Radium dry break couplers use a bayonet style lock that will not leak when disconnected nor introduce air upon reconnection. Simply push and twist the knurled machined surface. They are designed for use in fuel or oil applications and are available in 6AN and or 8AN flare fittings. The couplers have been successfully tested on Radium's test bench
