The Bomag 05544099 Test Connection is a genuine OEM service component designed for a broad range of Bomag tandem rollers, single drum rollers, and compactors. As an authentic Bomag part, this test connection is manufactured to the exact specifications required for accurate hydraulic system diagnostics across compatible equipment. It fits models including the BW 141 AD-5, BW 151 AD-5, BW 161 AD-50, BW 202 AD-50, BW 206 AD-5, BW 145 DH-5, BW 177 DH-5, BC 473 RB-4, BC 473 RS-4, and BC 473 EB-4, among others. When a hydraulic circuit needs to be checked, having the correct test connection — part number 05544099 — ensures readings are reliable and your diagnostic process stays on schedule.
Key Features
- OEM-Accurate Port Sizing — manufactured to Bomag's exact thread and port specifications, so pressure gauge and diagnostic tool connections seat correctly without adapters or improvised fittings
- Direct Service Fit — installs into the hydraulic test point as a direct replacement, matching the original connection geometry used across the BW-series tandem and single drum roller lines and BC-series compactors
- Wide Equipment Coverage — compatible with Bomag BW 141 AD-5, BW 151 AD-5, BW 154 AD-5, BW 191 AD-5, BW 206 AD-5, BW 145 DH-5, BW 177 DH-5, BW 177BVC-5, BC 473 RB-4, BC 473 RS-4, BC 473 EB-4, and additional BW and BC variants
- Diagnostic Integrity — a correctly functioning test connection delivers a leak-free seal at the test point, producing accurate pressure readings; a damaged or incorrect fitting can introduce measurement error or mask real hydraulic faults
- Genuine Bomag Part — sourced directly through authorized Bomag supply channels, ensuring the component you install matches the original part in material grade, thread form, and dimensional tolerance
A test connection is a small but essential hydraulic service fitting that provides a dedicated access point for connecting pressure gauges, flow meters, or other diagnostic instruments to a machine's hydraulic circuit. It allows technicians to measure system pressure at specific points in the circuit without opening lines or risking contamination. When a test connection is damaged, corroded, or missing, accurate hydraulic diagnosis becomes difficult — leading to misdiagnosis, extended repair time, or unnecessary component replacement. Using the correct OEM fitting, such as part number 05544099, ensures the connection interfaces properly with both the machine port and the diagnostic equipment.
