Wacker Neuson 5000114393 Grease Fitting M6X1 90 Degree

The Wacker Neuson is a genuine OEM Grease Fitting M6X1 90 Degree designed for RD-series tandem rollers and RT-series vibratory trench rollers. This 90-degree angle fitting is a direct OEM replacement sourced from Wacker Neuson, ensuring the thread pitch, body geometry, and check-valve action match the original specification exactly. Compatible across a broad range of machines including the RD12, RD16, RD27, RT56, RT82, RTx, and RTLx series, part number covers an extensive lineup of walk-behind and ride-on compaction equipment. Having the correct fitting in place keeps lubrication intervals on schedule and protects critical pivot and bearing points from premature wear.

Key Features

• OEM-Spec Thread Engagement — M6x1 thread pitch matches the original tapped bore precisely, ensuring full thread engagement and a leak-free grease seal every time.
• 90-Degree Body Angle — The right-angle configuration allows grease gun access in tight, recessed lubrication points where a straight fitting simply cannot reach.
• Broad Roller Family Coverage — Fits RD12, RD16, RD27 tandem rollers and RT56-SC, RT82-SC, RTx-SC2, and RTLx-SC3 vibratory trench rollers across multiple machine numbers and configurations.
• Protects Bearings and Pivot Points — A functioning grease fitting delivers lubricant directly to wear surfaces; a damaged or clogged fitting starves those surfaces and accelerates bearing failure.
• Genuine Wacker Neuson OEM Part — Manufactured to the same material and dimensional standards as the original, so the check-valve seats correctly and grease flows at normal gun pressure without bypassing or blowback.

A grease fitting — also called a zerk or grease nipple — is the entry point through which lubricant is forced into a bearing, joint, or pivot under pressure from a grease gun. The spring-loaded check valve inside the fitting opens under pressure to admit grease, then closes to prevent contamination from entering the lubrication point. On tandem rollers and trench rollers like those in the RD and RT families, these fittings service drum bearings, articulation joints, and other high-load pivot points that must be lubricated on a regular maintenance schedule. When a fitting is stripped, corroded, or broken off, lubrication becomes impossible at that point — leading to accelerated wear, overheating, and eventual component failure if not addressed promptly.
