The Wacker Neuson Test Fitting with Cap is a genuine OEM component designed for the RT82-SC2, RTx-SC2, RTLx-SC3, RTKx-SC3, and RTL82-SC3 remote-controlled trench roller series, as well as the RD7 and RD27 tandem roller families. As a direct OEM replacement, part ships exactly as specified by Wacker Neuson, ensuring it integrates correctly with existing hydraulic or pressure test points on your machine. This fitting is built to the same standards as the original, supporting accurate on-machine diagnostics without the risk of mismatched threads, incorrect pressure ratings, or fluid contamination introduced by an ill-fitting substitute. Whether you are servicing a trench roller fleet or maintaining RD27 ride-on rollers, having the right test fitting with cap on hand keeps your service workflow moving.
Key Features
- Genuine OEM Thread and Pressure Integrity — Manufactured to Wacker Neuson's exact thread form and pressure-rating specification, so test port readings are accurate and leak-free every time.
- Protective Cap Included — The integrated cap seals the test port between service intervals, preventing contamination, moisture ingress, and hydraulic fluid weepage at the fitting.
- Broad Roller Family Coverage — A single part number serves the RT82-SC2, RTx-SC2, RTLx-SC3, RTKx-SC3, and RTL82-SC3 trench roller lines, plus RD7 and RD27 tandem roller models, simplifying inventory management across a mixed fleet.
- Drop-In Service Port Replacement — Replaces the original fitting at the same test point location with no rework to surrounding hardware, keeping scheduled hydraulic system checks on track.
- Hydraulic System Safety — A correctly seated test fitting with cap prevents unintended pressure release and fluid exposure during routine inspections — critical when working with high-pressure hydraulic circuits on compaction rollers.
A test fitting with cap provides a dedicated access point on a machine's hydraulic circuit, allowing technicians to connect a pressure gauge or diagnostic tool and read system pressure without opening the circuit completely. The protective cap covers the port when not in use, keeping contaminants out of the hydraulic system and maintaining circuit integrity between service intervals. When this fitting is missing, damaged, or incorrectly threaded, accurate pressure diagnostics become unreliable and the exposed port becomes a potential entry point for dirt and moisture — both of which can cause accelerated wear or failure in hydraulic components.
