Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's exact compound and durometer specifications, delivering the compression and chemical resistance this sealing application demands.
- Drop-In Replacement — Matches the original groove dimensions and cross-section profile, seating cleanly without trimming or adjustment.
- Broad Equipment Compatibility — Fits the RD12A-90 roller series, CRT36-26A and CRTv36-26A trowel series, BFS 2020AS saw, GS12Ai, and GPS9700A machines.
- Leak Prevention — A correctly seated O-Ring maintains fluid and pressure containment across its mating surfaces; a worn or flattened seal leads to leaks, pressure loss, and accelerated wear on surrounding components.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so part number 5000226549 carries the same quality assurance as the original component installed at the factory.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces, creating a pressure-tight or fluid-tight barrier when the joint is assembled. On construction equipment like compaction rollers, power trowels, and saws, O-Rings are used throughout hydraulic circuits, fuel systems, and mechanical assemblies wherever a leak-free connection is critical. When an O-Ring hardens, cracks, or becomes compressed beyond its service limit, it loses its ability to seal — allowing fluids to escape, contaminants to enter, and pressure to drop, all of which can cause secondary damage to pumps, cylinders, or other precision components if left unaddressed.
