Replacement silencer ring for the UMS 7-50cc, the seven-cylinder 50cc four-stroke radial from UMS.
Function: it is the silencer ring, which seals and locates the silencer at its joint.
The reason this ends up on an order: a failed ring is an exhaust leak that also lets the joint move and work loose.
Fitting note: Renew the ring whenever the silencer is removed and check the joint faces.
