The Wacker Neuson O-Ring 17 X 1.1 is a genuine OEM seal designed for the RD7H-ES and RD 7ES tandem roller series. Sourced directly from Wacker Neuson, this O-ring meets the exact material and dimensional standards specified for these machines, ensuring a proper seal every time. It is a direct-fit replacement for the original component, compatible with the RD7H-ES Tandem Roller and RD 7ES models.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's specified compound and durometer rating for this application, delivering the compression and chemical resistance required in roller hydraulic and fluid systems.
- Exact Dimensional Fit — At 17 x 1.1 mm, this O-ring matches the original groove dimensions precisely, seating correctly without adjustment or trimming during installation.
- Confirmed Fitment — Verified for the RD7H-ES Tandem Roller and RD 7ES series, so you can order with confidence knowing this is the correct part for your machine.
- Leak-Free Performance — A correctly seated O-ring maintains system pressure and prevents fluid ingress or loss; a worn or damaged seal can cause leaks that affect hydraulic function and contaminate surrounding components.
- Genuine Wacker Neuson Part — Carries the full backing of Wacker Neuson's OEM supply chain, ensuring consistent quality across every unit.
An O-ring is a precision sealing element that sits within a machined groove to create a pressure-tight barrier between mating components. In compaction equipment like the RD7H-ES Tandem Roller, O-rings are used throughout hydraulic circuits, fluid passages, and mechanical assemblies to prevent leaks and maintain correct operating pressure. When an O-ring degrades — through heat cycling, chemical exposure, or compression set — it loses its ability to seal, leading to fluid leaks, pressure loss, and potential damage to surrounding components. Replacing a worn O-ring promptly with the correct OEM part restores the integrity of the seal and keeps the system operating as designed.
