Key Features
- Genuine OEM Specification — manufactured to Bomag's exact tolerances and connection standards, ensuring correct port sizing, thread pitch, and pressure rating for hydraulic or diagnostic test points
- Direct-Install Replacement — this test connection integrates with existing ports and fittings on compatible machines without the need for adapters or modification
- Broad Bomag Fitment — fits BF 600 series pavers and an extensive range of BW tandem rollers, single drum rollers, and walk-behind rollers, including the BW 213 DH-4, BW 226 DH-4i, BW 154 AP-4 AM, BW 177BVC-5, BW 900-2, and BW 90 SL-5, among others
- Accurate Diagnostic Access — a correctly functioning test connection allows technicians to safely attach pressure gauges and diagnostic equipment to the hydraulic or fluid circuit, enabling precise system readings and faster fault diagnosis
- System Integrity Protection — a damaged or leaking test connection can compromise hydraulic circuit pressure readings and introduce contamination; replacing it with an OEM part restores proper sealing and measurement accuracy
A test connection is a dedicated diagnostic access point built into a machine's hydraulic or fluid system, allowing technicians to attach pressure gauges, flow meters, or other diagnostic tools without opening the circuit to the atmosphere. It provides a clean, repeatable measurement point that is essential for troubleshooting hydraulic faults, verifying system pressure, and performing routine service checks. When a test connection is damaged, corroded, or missing, accurate diagnosis becomes difficult and the risk of fluid contamination or pressure loss during testing increases significantly.
