The Wacker Neuson 5100011664 is a genuine OEM Hose Fitting designed for the RD18, RD24, RD27, and RD28 series tandem rollers. Sourced directly from Wacker Neuson, this fitting matches the exact specifications of the original component installed at the factory. It covers an extensive range of configurations across the RD series lineup, including Open Roll, Combination, and US-market variants. When a hydraulic or fluid line connection needs servicing on your tandem roller, the 5100011664 ensures you're reinstalling the correct fitting the first time.
Key Features
- Genuine OEM Fluid-Path Integrity — Manufactured to Wacker Neuson's original thread form, bore size, and sealing geometry so fluid pressure and flow rate are maintained exactly as the system requires.
- Direct-Connect Replacement — Mates to existing hose ends and port connections without rework, matching the original fitting orientation and torque specification of the RD series roller.
- Broad RD Series Coverage — Confirmed fitment across RD18-80, RD18-100, RD24-100, RD27-120, and RD28-120 tandem rollers in Open Roll, Combination, SE, and US-market configurations.
- Leak-Free System Performance — A failed or cross-threaded hose fitting causes pressure loss, fluid contamination, or complete hydraulic failure; this OEM fitting restores the sealed connection the roller depends on for consistent drum drive and vibration output.
- Hydraulic System Safety — Correct fitting material grade and thread specification prevent fitting pull-out or burst failure under operational pressure — a critical consideration on a machine compacting asphalt under load.
A hose fitting is a threaded connector that joins a hydraulic or fluid hose to a port on a pump, valve, or actuator within the machine's fluid circuit. On tandem rollers like the RD18, RD24, RD27, and RD28, these fittings carry hydraulic fluid that powers the drum drive motors and the eccentric vibration system responsible for compaction force. When a fitting corrodes, strips, or cracks, the resulting leak starves downstream components of pressure, causing erratic drum behavior, loss of vibration, or a full hydraulic shutdown — all of which halt production on the paving crew. Replacing a damaged fitting promptly with the correct OEM part restores circuit integrity and prevents collateral damage to hoses and connected components.
