Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact thread form and material spec required for a secure, leak-free hydraulic or fluid connection on these roller models.
- Direct Screw-In Replacement — Threaded fitment matches the original port geometry, allowing straightforward installation without reworking fittings or adapters.
- Broad RD-Series Compatibility — Fits the full RD40-130 and RD45-140 family, including standard, C (combination), O (open-drum), US, DPF, and .3 series tandem rollers.
- Maintains System Pressure and Flow — A correctly seated screwed socket preserves the integrity of the fluid circuit; a damaged or incorrect fitting can cause pressure loss, leaks, or system contamination.
- Verified by OEM Part Number — Sourced directly from Wacker Neuson, so the thread pitch, hex size, and sealing surface match what left the factory originally.
A straight screwed socket is a threaded fitting used to connect hydraulic lines, hoses, or fluid passages within a machine's plumbing circuit. It provides a sealed, pressure-rated junction point that keeps fluid routed correctly between components such as pumps, valves, and cylinders. When a socket becomes cracked, stripped, or corroded, the connection can weep fluid or lose pressure entirely, compromising the hydraulic system's ability to drive drum vibration or propulsion — making prompt replacement essential to keeping the roller operating at full capacity.
