A o-ring (sealing ring) to suit the UMS 7-50cc — the seven-cylinder 50cc four-stroke radial from UMS.
On this engine the component is a general-purpose sealing ring used at several joints on the engine.
Why this part matters: O-rings are consumables and harden with heat, so they are renewed rather than reused.
Fitting note: Match material and size to the application — not all O-rings are fuel or oil resistant.
