The Wacker Neuson O-Ring is a genuine OEM component designed for the RD12-90 Double Drum Roller and CRT36-25 Ride-on Trowel series. As a direct factory replacement, this O-Ring is produced to the exact material and dimensional standards required by Wacker Neuson, ensuring a correct, leak-free fit every time. It covers both the standard and foldable ROPS configurations of the RD12-90, as well as all CRT36-25 variants including the Wheel Kit-equipped and CRT36-26A-WK models. When a seal needs replacing, using the correct OEM part like the protects the integrity of the hydraulic or fluid system it serves.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's exact compound and durometer specification, delivering the compression and chemical resistance this application demands.
- Drop-In Replacement — Matches the original groove dimensions precisely, seating cleanly without reworking the housing or mating surfaces.
- Broad Model Coverage — Fits RD12-90 Double Drum Rollers (standard and foldable ROPS) and all CRT36-25 Ride-on Trowel configurations, including Wheel Kit and CRT36-26A-WK variants.
- Leak Prevention — A correctly installed O-Ring maintains fluid containment and system pressure; a worn or damaged seal leads to fluid loss, contamination, and accelerated component wear.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so you receive the same part installed at the factory — not a generic approximation.
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or components, creating a pressure-tight barrier that prevents fluid or air from escaping. In compaction and finishing equipment like the RD12-90 roller and CRT36-25 trowel, O-Rings are critical wherever hydraulic fluid, oil, or coolant must be contained within a system. When an O-Ring hardens, cracks, or becomes compressed beyond its service limit, it loses its ability to seal — leading to fluid leaks, pressure loss, and potential damage to surrounding components. Replacing a failed O-Ring promptly with the correct OEM part restores the system to its designed operating condition.
