Wacker Neuson 5100034682 Union Nut

The Wacker Neuson Union Nut is a genuine OEM component designed for the RC110 and RC110p series ride-on compactors, covering ROPS and CAB configurations across both standard and US-spec variants. As a direct OEM part, it is manufactured to the exact tolerances and thread specifications required by Wacker Neuson, ensuring a clean, secure connection every time. This union nut fits across the full RC110 and RC110p lineup, including Compactor RC110 US ROPS, Compactor RC110p US ROPS, Compactor RC110 US CAB, and Compactor RC110p US CAB models. When you need a part that installs correctly the first time without guesswork, sourcing genuine OEM is the straightforward choice.

Key Features

• OEM Thread Integrity — Manufactured to Wacker Neuson's exact thread profile and torque specification, so the union nut seats and seals as intended — not close enough, but exactly right.
• Drop-In Replacement — Matches the original mounting interface on RC110 and RC110p compactors, threading directly into the existing connection point without rework or adaptation.
• Broad RC110 Series Coverage — A single part number covers standard, US-spec, ROPS, and CAB variants of both the RC110 and RC110p, keeping your parts inventory simple.
• Secure Fluid or Line Connection — A correctly torqued union nut maintains a leak-free joint in hydraulic or fuel line connections; a worn or damaged nut risks loosening under vibration and causing fluid loss or pressure drop.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson's OEM parts program, carrying the same part number — 5100034682 — used by authorized dealers and service centers.

A union nut is a threaded fastening component used to join two sections of pipe, tubing, or fittings in a way that allows the connection to be made and released without rotating the pipes themselves. On ride-on compactors like the RC110 series, union nuts are typically found in hydraulic or fluid line assemblies where a secure, vibration-resistant connection is critical to system pressure and performance. A cracked, stripped, or missing union nut can result in fluid leaks, pressure loss, or line separation — any of which will take the machine out of service until the fitting is replaced.
