The Wacker Neuson Exhaust Seal is a genuine OEM exhaust seal designed for the BFS 914A, BFS 914AB, BFS 935A, BFS 940, BFS 940A floor saws, and RD7Af HRC series. As a factory-sourced component, this seal is produced to the exact material grade and compression specification required for correct exhaust sealing on these machines. It is a direct-fit replacement for all listed BFS and RD7Af HRC models, including both the gasoline-powered BFS 940A and the BFS 935A Basic configurations.
Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compression rating and heat-resistant material grade required for exhaust applications on Wacker Neuson floor saws and compactors.
- Drop-In Exhaust Port Fit — Engineered to match the exact exhaust port geometry of compatible models, seating correctly without trimming or adaptation.
- Broad BFS and RD7Af Series Coverage — Fits BFS 914A, BFS 914AB, BFS 935A, BFS 940, BFS 940A, RD7Af HRC, and RD7Afb HRC machines across multiple build configurations.
- Sustained Engine Efficiency — A correctly sealed exhaust joint maintains proper back-pressure and prevents hot gas leakage, which can lead to power loss, overheating, and accelerated wear on surrounding components.
- Exhaust Leak Prevention — A failed or degraded exhaust seal allows combustion gases to escape at the joint, creating a safety risk for operators working in close proximity to the machine. Replacing with a genuine OEM seal restores the designed exhaust containment.
An exhaust seal sits at the junction between the engine's exhaust port and the exhaust system, creating a gas-tight barrier that keeps hot combustion gases routed correctly out of the machine. When this seal is intact, the engine runs at its intended efficiency and exhaust gases are safely directed away from the operator's environment. Over time, the repeated heating and cooling cycles of normal operation cause the seal to compress, harden, or crack, leading to exhaust leaks that reduce engine power, increase operating temperatures, and expose nearby workers to harmful fumes.
