The Wacker Neuson Rubber Bleeder Valve is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including traction control-equipped variants. As a direct factory replacement, part is manufactured to the same specification as the original, ensuring a correct, trouble-free installation with no guesswork. This valve fits across a wide range of RD27 machine configurations, making it a reliable sourcing choice whether you are servicing a standard or traction control model.
Key Features
- Genuine OEM Rubber Compound: — Produced from the same rubber formulation as the original, ensuring consistent compression, sealing performance, and resistance to hydraulic fluid exposure over time.
- Drop-In Replacement: — Engineered to match the original bleeder valve port geometry on RD27 rollers, so it seats and seals correctly without modification.
- Broad RD27 Series Coverage: — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across multiple machine numbers, including both standard and traction control configurations.
- Maintains Hydraulic System Integrity: — A correctly functioning bleeder valve allows trapped air to be purged from the hydraulic circuit; a failed or cracked valve compromises system pressure and bleeder procedure effectiveness.
- Fuel and Fluid Resistant: — The rubber construction is compatible with the hydraulic media used in RD27 hydrostatic drive systems, resisting swelling and degradation under normal service conditions.
A bleeder valve provides a controlled point in a hydraulic or fluid circuit where trapped air can be released during system servicing or after component replacement. On hydrostatic vibratory rollers like the RD27 series, purging air from the drive circuit is essential — air in the system causes inconsistent drive response, reduced compaction force, and potential damage to hydraulic components. When the rubber bleeder valve cracks, deforms, or fails to seal properly, the bleed procedure cannot be completed correctly, leaving air in the system and compromising roller performance and control.
