Description
Overview:
This Exhaust Gasket is a genuine Briggs & Stratton replacement for sealing the joint between the cylinder head/exhaust port and the muffler or exhaust manifold on larger petrol engines. Manufactured from heat-resistant composite materials designed to cope with thermal cycling and vibration, it helps maintain a gas‐tight seal, reducing exhaust leaks, noise, and loss of performance. It is engineered for Briggs & Stratton V‐Twin engines used in professional turf and machinery applications, including the 543477-3035-J1 31 HP (approx. 23.1 kW) and 613777-0116-J1 36 HP (approx. 26.8 kW) variants. As a Genuine Part referenced by OEM No. 809872, it matches the original dimensions and bolt-hole spacing for straightforward installation and reliable service life in construction and garden equipment.
Key Features:
- Genuine Briggs & Stratton part for assured compatibility with specified engines (OEM No. 809872)
- Heat‐resistant composite construction helps prevent blow‐by and exhaust leaks under high temperature loads
- Precise cut-outs and hole spacing for accurate alignment and a consistent seal
- Supports correct exhaust back pressure, aiding stable idle and overall engine efficiency
- Durable against thermal cycling, vibration, and exhaust moisture for long service life
- Direct replacement part that fits without modification, helping minimise downtime
- Suitable for heavy‐duty use on commercial turf and plant machinery where reliability is critical
- Supplied as a single gasket; replace whenever the exhaust joint is disturbed for best results
Typical Applications:
Used on Briggs & Stratton V‐Twin engines powering ride‐on mowers, zero‐turn mowers, garden tractors, chipper/shredders, stump grinders, and other compact plant and landscaping equipment. Ideal when refitting a muffler, servicing the exhaust, or resolving exhaust leak noises, fumes, or soot traces at the manifold joint.
