The Bomag 05548309 Angular Flange Union is a genuine OEM hydraulic fitting designed for an exceptionally broad range of Bomag heavy equipment, including BM-series cold milling machines, BW-series tandem rollers, BC-series refuse and landfill compactors, BF-series pavers, and MPH-series recyclers and stabilizers. Sourced directly from Bomag, this fitting matches the original part in geometry, thread specification, and angle orientation — ensuring a leak-free, code-compliant connection every time. This angular flange union installs directly into the existing hydraulic circuit without rework, making it the correct choice for fleet maintenance and machine rebuilds alike. Confirmed fitment spans models including the BM 1000/35, BM 2500/75, BW 120 AD-5, BC 772 RB, BF 300 P-2 S340-2 TV, and MPH 122, among many others.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original thread form, wall thickness, and angle specification, delivering the sealing performance expected from a factory-sourced hydraulic fitting
- Angled Orientation for Tight Routing — the angular flange design allows hydraulic lines to change direction within confined machine cavities, replacing the original fitting with identical geometry and port alignment
- Broad Cross-Family Fitment — confirmed for BM cold milling machines, BW tandem rollers, BC refuse and landfill compactors, BF pavers, and MPH and RS recyclers and stabilizers, covering an extensive range of Bomag heavy equipment
- Leak Prevention at High Operating Pressure — a correctly seated angular flange union maintains hydraulic circuit pressure and prevents fluid loss that would otherwise cause erratic system response or component damage
- Fuel and Fluid System Safety — as a hydraulic line fitting, proper torque and OEM-spec sealing surfaces are critical; using the correct part number 05548309 ensures the joint meets the pressure ratings of the original circuit design
An angular flange union is a rigid hydraulic connector that joins two fluid lines at a fixed angle, allowing the circuit to be routed around structural members and adjacent components within the machine's frame. It uses a flanged sealing face rather than a simple threaded joint, which distributes clamping load evenly and maintains a reliable seal under sustained hydraulic pressure and vibration. When this fitting corrodes, cracks, or develops thread damage, the hydraulic circuit can lose pressure, introduce air, or leak fluid — any of which will degrade steering, drive, or auxiliary system performance until the fitting is replaced.
