UMS 7-160cc TEFLON BUSH INLET PIPE ( X 10 QTY / Pack)

This is the teflon bush inlet pipe for the UMS 7-160cc engine, the seven-cylinder 160cc four-stroke radial from UMS.

The part itself is the PTFE (Teflon) bush in the inlet pipe, which allows the pipe to move without an air leak.

Why it is replaced: the bush is what keeps the joint sealed while isolating vibration, and a worn bush leaks air into the induction. Supplied as a pack of 10, which is how these small parts are normally bought — you rarely need just one.

Fitting note: Do not substitute a plain bush — PTFE is chosen for the temperature and for low friction.
