The Wacker Neuson O-Ring is a genuine OEM seal designed for the CRT36-25 and CRT36-26A-WK 915mm ride-on trowel series, including Wheel Kit-equipped configurations. Sourced directly from Wacker Neuson, this O-Ring meets the exact material and dimensional specifications of the original part installed at the factory. Keeping the correct seal in place is critical to maintaining fluid integrity and preventing contamination in the systems that keep your trowel running at full performance.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compound and durometer specifications, ensuring the correct compression set and resistance to fluids encountered in trowel operation.
- Drop-In Seal Replacement — Matches the exact cross-section and diameter of the original, seating cleanly into the same groove without reworking the mating surfaces.
- Confirmed CRT36-25 Series Fitment — Verified for the CRT36-25 and CRT36-26A-WK ride-on trowels, including standard and Wheel Kit variants across multiple build configurations.
- Leak-Free System Integrity — A properly seated O-Ring prevents fluid bypass and contamination ingress; a failed or hardened seal can lead to pressure loss, fluid leaks, and accelerated wear on surrounding components.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, so you receive the same part used in original production — not a generic substitute.
An O-Ring is a precision-formed loop seal that sits in a machined groove between two mating surfaces or around a moving shaft, creating a pressure-tight barrier that keeps fluids in and contaminants out. On a ride-on trowel like the CRT36-25, O-Rings are used throughout hydraulic, lubrication, and fluid management circuits where maintaining a leak-free connection is essential to consistent machine operation. When an O-Ring ages, hardens, or becomes pinched during servicing, it loses its ability to seal effectively — resulting in fluid seepage, pressure drop, or contamination that can damage the components it was protecting.
