The Wacker Neuson Cavity Plug is a genuine OEM component designed for RD27-100 and RD27-120 hydrostatic vibratory rollers. As a factory-original part, is manufactured to the exact specifications required for proper sealing and hydraulic system integrity on RD27-series tandem rollers. This plug is confirmed to fit across multiple machine configurations, including standard and traction control variants of both the RD27-100 and RD27-120.
Key Features
- Factory-Original Sealing Integrity — Manufactured to OEM tolerances, ensuring the cavity is sealed to the exact pressure and dimensional specification required by the RD27 hydraulic system.
- Direct Drop-In Fitment — Engineered to thread or seat into the designated cavity port without additional hardware, matching the OEM installation interface exactly.
- Broad RD27 Series Coverage — Confirmed fit across RD27-100 and RD27-120 configurations, including standard hydrostatic vibratory roller and traction control variants.
- Hydraulic System Protection — A properly seated cavity plug prevents fluid ingress, contamination, and pressure loss at unused or plugged ports — keeping the hydrostatic drive circuit operating correctly.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, ensuring the part number 5000162249 matches your machine's parts documentation without substitution risk.
A cavity plug is used to seal off unused ports or machined cavities within a hydraulic valve body, manifold, or housing. Its primary role is to block fluid flow through ports that are not in active use, preventing leaks, contamination, and unintended pressure paths within the hydraulic circuit. On a hydrostatic vibratory roller like the RD27-100 and RD27-120, where precise hydraulic pressure management governs both drive and vibration functions, a missing or damaged cavity plug can result in pressure loss, erratic machine behavior, or hydraulic fluid leaks that compromise both performance and safe operation.
