The Wacker Neuson is a genuine OEM O-Ring designed for a broad 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. Sourced directly from Wacker Neuson, this O-Ring matches the exact material grade, durometer, and dimensional tolerancing of the original component. It installs as a direct drop-in replacement with no modification to mating surfaces or hardware. Whether you're servicing a pump, heater, roller, or rammer, part number ensures a proper seal the first time.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and hardness specifications, ensuring correct compression and long-term sealing integrity under pressure and temperature cycling.
- Direct Drop-In Replacement — Matches the original O-Ring's cross-section and inner diameter exactly, seating cleanly into existing grooves without reworking any mating surfaces.
- Wide Cross-Machine Fitment — Confirmed for HSH350 hydronic surface heaters, PT2H and PT3H trash pumps, RD7H tandem rollers, and DS70 diesel rammers — one part number covering multiple machine families.
- Leak Prevention Where It Counts — A correctly seated O-Ring maintains fluid and pressure containment in pumps, heating circuits, and hydraulic passages; a worn or cracked ring causes fluid loss, pressure drop, and potential machine shutdown.
- Fluid System Safety — Proper sealing in fuel, hydraulic, and heating circuits prevents unintended fluid contact with hot surfaces or electrical components, supporting safe machine operation.
An O-Ring is a molded elastomeric seal that sits in a machined groove between two mating surfaces, creating a pressure-tight barrier against fluid or gas leakage. In equipment like trash pumps and hydronic heaters, O-Rings are critical to maintaining system pressure and preventing fluid loss at connection points, port faces, and housing joints. When an O-Ring degrades — through heat cycling, chemical exposure, or simple age — it loses its ability to compress and seal evenly, leading to visible leaks, reduced system efficiency, or contamination of surrounding components.
