Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's specified compound and durometer rating, delivering the compression and chemical resistance required for this application.
- Drop-In Replacement — Matches the original groove dimensions exactly, seating flush without adjustment or trimming during reinstallation.
- Broad Model Coverage — Compatible with the BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series, making it the correct choice across multiple Wacker Neuson pump platforms.
- Leak-Free Performance — A correctly seated O-Ring maintains internal pressure and prevents fluid or air ingress; a worn or damaged one can cause immediate loss of system integrity and operational failure.
- Genuine Wacker Neuson Part — Sourced directly through the OEM supply chain, part number 5100067191 is traceable and verified for these specific models.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or around a shaft or port. Its job is to prevent fluid, air, or pressure from escaping the sealed joint under both static and dynamic conditions. When an O-Ring hardens, cracks, or deforms over time, the seal breaks down — leading to leaks, pressure loss, and potential damage to surrounding components if left unaddressed.
