Description
Overview:
The O-Ring 35x3-FPM 80 is a genuine Stihl sealing ring designed for a dependable, leak-free joint in fuel, air and fluid systems across a wide range of Stihl machines, including the SH55 and SH85. Made from FPM 80 (fluoroelastomer), it offers strong resistance to petrol, oils, solvents, heat and ozone, helping maintain stable performance under demanding use. Its size is 35 x 3 mm (1.38 x 0.12 inches), matching Stihl specifications for a precise fit. Use it to restore sealing integrity around housings, caps, manifolds and covers where a round-section O-ring is specified. As a genuine Stihl part, it supports reliable operation, reduces the risk of air leaks and pressure loss, and is suitable for routine servicing or repairs.
