Replacement O-ring for the external male coupling on Frigoboat's quick disconnect fittings. One is required for each fitting.
Internal, smaller O-rings are available, but require the evacuation and recovery of the gas from your system, and the complete disassembly of the fittings. There is a #29 O-ring in each of the fittings. It is rare that these o-rings need replacing. Please contact us direct if you need further assistance.
