Ideal for maintenance, refurbishment, or when installing a carburetor kit, this O-ring installs quickly during the disassembly of the float. Check the condition of the O-ring during each intervention (cracks, flattening, or hardening) and replace it if worn to avoid gasoline drips or localized pressure loss.

Workshop tip: before installation, clean the seating surfaces and lightly lubricate the O-ring with a suitable silicone grease to facilitate assembly and prevent pinching. A simple yet crucial spare part to maintain the sealing of the Mikuni carburetor.
