The Wacker Neuson is a genuine OEM O-Ring designed for a wide range of Wacker Neuson equipment, including HSH350 hydronic surface heaters, PT2H and PT3H centrifugal trash pumps, RD7H series tandem rollers, and the DS70 vibratory rammer. As a factory-sourced component, it is manufactured to the exact material and dimensional specifications required for a proper, leak-free seal. This O-Ring is a direct-fit replacement that restores the fluid or pressure seal at its intended joint without additional modification. Keep a spare on hand — this is the kind of small part that stops a machine cold when it fails.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact elastomer compound and dimensional tolerances, ensuring consistent compression and sealing performance at the intended pressure and temperature range.
- Cross-Family Compatibility — A single part number that serves multiple machine families: HSH350 hydronic surface heaters, PT2H and PT3H trash pumps, RD7H tandem rollers, and the DS70 diesel rammer — simplifying parts stocking across your fleet.
- Drop-In Replacement — Seats directly into the original groove without trimming or stretching, maintaining the correct compression ratio for a positive seal on reinstallation.
- Protects Against Fluid Loss and Contamination — A failed or aged O-Ring allows fluid leakage or contaminant ingress, which can lead to pump cavitation, hydraulic pressure loss, or overheating in heating equipment. This replacement restores the barrier that keeps those systems running correctly.
- Critical Fluid System Component — In pump and heating applications especially, O-Ring integrity is directly tied to system pressure and safe operation. Using the correct OEM-spec O-Ring ensures the seal performs within the system's designed pressure envelope.
An O-Ring is a small but essential sealing component used at joints, ports, and connections throughout fluid-handling and hydraulic systems. Its job is to create a pressure-tight barrier between two mating surfaces, preventing liquid or gas from escaping the system. Over time, heat cycling, chemical exposure, and mechanical compression cause O-Rings to harden, crack, or flatten — once the seal is compromised, the machine will leak, lose pressure, or allow contamination into sensitive passages. Replacing a worn O-Ring promptly with the correct part is one of the most cost-effective ways to prevent larger mechanical failures downstream.
