Replacement O-ring for the external male coupling on Frigoboat's quick disconnect fitting. Only one is required for each fitting. O-ring location shown in picture.

Internal, smaller O-rings are available, but not pictured. Replacing the internal O-rings requires a trained marine refrigeration professional to evacuate and recover the gas from your system and a complete disassembly of the fittings. Then the system needs to be recharged. It is rare the internal O-rings need replacing.
