232239 76 Description O Ring Drain Plug

The Mikuni HSR drain plug O-ring is a specialized seal for the float bowl drain plug on HSR series carburetors. This O-ring prevents fuel from weeping out of the drain port, ensuring the fuel system remains sealed and safe. Constructed from fuel-resistant material, it is designed to withstand constant exposure to gasoline without degrading or losing its sealing properties. Replacing this O-ring during routine maintenance or whenever the drain plug is removed is a simple way to prevent leaks and maintain the integrity of a Mikuni HSR42, HSR45, or HSR48 carburetor.
