The Bomag 05553431 Angular Union is a genuine OEM component designed for a wide range of Bomag tandem rollers, vibratory plates, and reversible vibratory plates — including the BW 138 AD, BW 120 AD-5, BW 174 AP-4, BP 25/48 D, BPR 25/40, and BPR 40/45 D series, among many others. As a direct OEM part, this angular union matches the original specification exactly, ensuring a correct installation without the need for modifications or improvised fittings. Sourced directly through authorized channels, part number 05553431 is the right choice for operators who demand accuracy and dependability in their hydraulic or fluid connections.
Key Features
- Genuine OEM Specification — manufactured to Bomag's original design tolerances, ensuring the correct thread form, sealing angle, and connection geometry for this angular union application
- Direct-Fit Replacement — installs into the original port and connection point without rework, maintaining the integrity of the fluid circuit it serves
- Broad Fitment Coverage — confirmed fit across Bomag tandem rollers including the BW 80 AD-2, BW 100 AD-5, BW 138 AD-5, and BW 174 AP-4, as well as BP-series vibratory plates and BPR reversible vibratory plates such as the BPR 25/45 D-3 and BPR 40/45 D-3
- Fluid System Integrity — a correctly seated angular union maintains leak-free directional routing of hydraulic or fluid lines; a worn or incorrectly fitted union risks pressure loss and contamination ingress
- Genuine Part Traceability — part number 05553431 is the authoritative Bomag OEM reference, eliminating guesswork when cross-referencing against service manuals or parts catalogs
An angular union is a threaded fitting used to route a hydraulic or fluid line at a fixed angle — typically 45° or 90° — allowing hoses and tubes to change direction cleanly within confined machine spaces without stressing the line or the port. It forms a pressure-tight seal between two fluid circuit elements, and its geometry is critical: an incorrect angle or thread specification can cause leaks, restrict flow, or place mechanical strain on adjacent fittings. When an angular union fails or is replaced with an incorrect part, the result is often a slow hydraulic leak or intermittent pressure drop that affects machine control response and operational consistency.
