The Wacker Neuson Test Fitting With Metal Cap is a genuine OEM component designed for RD-series tandem rollers and RT-series vibratory trench rollers, including the RD12, RD12A, RD16, and RD27 families as well as RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 models. As a direct OEM replacement, the is manufactured to Wacker Neuson's exact specifications, ensuring a correct connection to the hydraulic or fluid circuit test port every time. This fitting ships with its protective metal cap intact, keeping the test port sealed and contamination-free during storage and whenever diagnostic access is not required.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's precise thread form and pressure ratings, so the fitting seats and seals exactly as the original did on the production line.
- Integrated Metal Cap — The included metal cap threads securely onto the fitting to block dirt, moisture, and debris from entering the test port between service intervals.
- Broad Cross-Family Fitment — Compatible with RD12, RD12A, RD16, and RD27 tandem rollers as well as RT56-SC, RT56-SC2, RT82-SC, and RT82-SC2 vibratory trench rollers, covering a wide range of Wacker Neuson compaction equipment.
- Accurate Diagnostic Access — Provides a clean, leak-free connection point for pressure gauges or test equipment, supporting accurate hydraulic system readings during servicing.
- Contamination Control — A missing or damaged test fitting cap allows particulates into the hydraulic circuit; replacing this assembly restores the system's first line of contamination defense.
A test fitting with metal cap is a threaded port fitting installed in a hydraulic or fluid circuit to allow technicians to connect diagnostic equipment — such as pressure gauges or flow meters — without permanently opening the system. The metal cap seals the port whenever the fitting is not in active use, preventing contaminants from entering the hydraulic circuit. When this fitting is cracked, cross-threaded, or its cap is lost, the test port is left exposed, which risks hydraulic fluid contamination and makes accurate pressure testing impossible — both of which can lead to undiagnosed system faults on the roller or trench roller.
