The Wacker Neuson Sealing Ring is a genuine OEM component designed for the RD18-80, RD18-100, and RD18-100 C tandem roller series. Sourced directly from Wacker Neuson, this sealing ring meets the exact material and dimensional standards of the original part fitted at the factory. It is confirmed compatible across multiple build variants including US and SE configurations of the RD18-80 and RD18-100 series, as well as the RD18-80.3 and RD18-100.3 models. When it comes to sealing components on compaction equipment, using a genuine OEM part ensures the integrity of the system is maintained and costly fluid loss or contamination is avoided.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material specification, ensuring correct compression characteristics and resistance to hydraulic fluid, heat, and operating pressure found in tandem roller applications.
- Direct Drop-In Replacement — Dimensionally identical to the original, this sealing ring seats correctly in its housing without the need for additional machining or adaptation.
- Broad RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100 C variants across standard, US, SE, and .3-series configurations, covering a wide range of Wacker Neuson tandem roller builds.
- Prevents Fluid Leakage and Contamination — A worn or damaged sealing ring allows fluid to escape or contaminants to enter, which can accelerate wear on surrounding components and lead to more extensive repairs.
- Genuine Wacker Neuson OEM Part — Part number 5100011554 is an authorized Wacker Neuson component, giving you confidence that you are installing the correct part for the application.
A sealing ring forms a pressure-tight barrier between mating components, preventing hydraulic fluid, lubricants, or other fluids from leaking past joints, fittings, or moving assemblies. On a tandem roller like the RD18 series, maintaining effective seals is critical to keeping hydraulic systems operating at the correct pressure and protecting internal components from contamination. When a sealing ring deteriorates — through heat cycling, compression fatigue, or chemical exposure — it can allow fluid to bypass the seal, leading to pressure loss, visible leaks, and accelerated wear on the parts it was protecting.
