The Wacker Neuson Sealing Ring is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard configurations and models equipped with Traction Control. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It is a direct-fit replacement for all listed RD27 series variants, covering a wide range of serial-number configurations across the RD27-100 and RD27-120 families.
Key Features
- OEM-Grade Sealing Integrity — Manufactured to the original material and dimensional spec, ensuring the sealing ring maintains correct compression and fluid containment within the hydrostatic drive system.
- Direct-Fit Replacement — Engineered to seat and seal exactly as the original, with no reworking or adapting of surrounding components required during installation.
- Broad RD27 Series Coverage — Compatible with multiple build configurations of the RD27-100 and RD27-120, including standard hydrostatic and Traction Control-equipped models.
- Protects Hydrostatic System Performance — A correctly seated sealing ring prevents fluid bypass and pressure loss that would otherwise compromise drum drive response and compaction output.
- Fuel and Fluid System Safety — A failed or degraded sealing ring can allow hydraulic fluid leaks that create slip hazards and potential system contamination; replacing promptly with a genuine OEM part restores safe operation.
A sealing ring creates a pressure-tight barrier between mating components in the hydrostatic drive or hydraulic circuit of the roller. Its primary job is to contain hydraulic fluid under pressure, preventing internal or external leaks that would reduce system efficiency or cause component damage. When a sealing ring wears, hardens, or deforms, the resulting fluid bypass leads to sluggish drum response, reduced compaction force, and — if left unaddressed — accelerated wear on pumps, motors, and surrounding seals.
