- Accurate System Diagnostics — a properly functioning test connection allows technicians to obtain precise pressure or flow readings, enabling correct fault diagnosis and preventing unnecessary component replacement
- Part Number Confidence — ordering by Bomag part number 05544022 ensures you receive the exact connection specified for your machine, eliminating the risk of a mismatched port size or fitting standard
A test connection is a dedicated diagnostic access point built into a machine's hydraulic or fluid system. It provides a secure, leak-free port where a technician can attach a pressure gauge, diagnostic tool, or test instrument to measure system pressure, verify flow, or check fluid condition without disassembling lines or components. When a test connection is damaged, corroded, or missing its sealing surface, readings become inaccurate or impossible to obtain, which can lead to misdiagnosis, extended service time, and the risk of operating a machine with an undetected hydraulic fault. Replacing a worn or leaking test connection restores the ability to perform fast, accurate on-machine diagnostics and keeps service procedures running efficiently.
