The Wacker Neuson is a genuine OEM O-Ring 62 X 3-70 Sh designed for the CT30, CT36, and CT48 series walk-behind concrete trowels. As a direct OEM part, the is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a proper seal wherever it is installed. This part fits an extensive range of CT series configurations including gas, diesel, electric, and variable-speed models across 30 in, 36 in, and 48 in trowel sizes.
Key Features
- OEM-Grade Elastomer Material — Manufactured to the correct durometer rating (70 Shore) and cross-section for consistent sealing performance in CT series trowel applications.
- Exact Dimensional Fit — Sized at 62 mm inner diameter with a 3 mm cross-section, matching the original groove geometry for a proper seat without modification.
- Broad CT Series Compatibility — Fits CT30, CT36, and CT48 walk-behind trowel models including gas, diesel, electric, and variable-speed variants in both standard and CE configurations.
- Sealing Integrity Under Operation — A correctly installed o-ring prevents fluid or lubricant ingress and egress at its respective joint; a deteriorated o-ring leads to leaks, contamination, and accelerated wear of surrounding components.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this part carries the correct part number 5000034321 and meets the specifications set for CT series concrete trowels.
An o-ring is a precision-molded elastomeric seal that sits in a machined groove and compresses between two mating surfaces to prevent the passage of fluids or contaminants. In a walk-behind concrete trowel, o-rings are used at key joints within the gear, lubrication, and hydraulic systems to maintain correct fluid levels and exclude debris. When an o-ring ages, hardens, or becomes damaged, it loses its ability to seal — resulting in fluid leaks, dry-running components, and potential damage to the assemblies it protects.
