The Wacker Neuson is a genuine OEM O-Ring 132 X 3 designed for the CT30, CT36, and CT48 series walk-behind concrete power trowels. As a direct OEM replacement, meets Wacker Neuson's original material and dimensional specifications, ensuring a correct seal wherever this ring is installed in the trowel's fluid or air circuit. This part covers an extensive range of CT series configurations, including gasoline, diesel, electric, variable speed, and CE-certified variants across the 30-inch, 36-inch, and 48-inch trowel families.
Key Features
- Correct Elastomer Dimensioning — Sized at 132 x 3 to match the original groove geometry in Wacker Neuson CT series trowels, ensuring full contact compression and a leak-free seal.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this O-ring is manufactured to the same material compound and cross-section tolerance as the original, not an approximated substitute.
- Broad CT Series Coverage — Fits CT30, CT36, and CT48 walk-behind trowel models in gasoline (AGP, AGT), diesel (ADP, ADT), electric (EDT), variable speed (AVP, AVT), and BDT configurations, including CE-certified variants.
- Leak Prevention — A properly seated O-ring maintains fluid or pressure integrity within the trowel's system; a cracked or compressed-out ring leads to leaks, contamination, and accelerated wear on surrounding components.
- Drop-In Installation — Seats directly into the original groove without machining or modification, making it suitable for field replacement or scheduled maintenance intervals.
An O-ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or along a shaft passage, preventing fluid or air from escaping under pressure. In a walk-behind concrete trowel, O-rings are used throughout the engine, gearbox, and hydraulic or fuel circuit interfaces to keep lubricants and fluids contained and contaminants out. When an O-ring ages, hardens, or sustains physical damage, it loses its ability to compress evenly in the groove, allowing leaks that can lead to oil loss, overheating, or premature wear of the components it protects.
