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.

Key Features:
- Genuine Stihl part for correct fit and reliable sealing
- FPM 80 fluoroelastomer for resistance to fuel, oil, heat and ozone
- Size: 35 x 3 mm (1.38 x 0.12 inches) to Stihl specification
- Withstands high temperature and pressure cycles in engine and blower systems
- Helps prevent air and fluid leaks for consistent starting and running
- Suitable for E5/E10 pump fuels and mixed two-stroke environments
- Smooth round cross-section seats cleanly in grooves and recesses
- Simple to replace during regular maintenance with basic tools
- Widely used across Stihl blowers, vacs, brushcutters, hedge trimmers, pole pruners, sprayers and cut-off saws

Typical Applications:
Replacement O-ring for sealing covers, housings, manifolds, carburettor interfaces and pump bodies on Stihl hand-held machines. Ideal when curing fuel seepage, vacuum leaks or pressure loss that affect starting, idle quality or performance. Use during routine overhauls, filter or hose changes, and when refitting components after inspection or cleaning.
