Bomag Angular Flange Union | Part 05548305

The Bomag 05548305 Angular Flange Union is a genuine OEM hydraulic fitting designed for a wide range of Bomag pavers, tandem rollers, walk-behind and light rollers, single drum rollers, cold milling machines, trench compactors, and reversible vibratory plates. Sourced directly from Bomag, this angular flange union meets the exact specifications of the original component it replaces. Compatible machines include BF-series pavers, BW-series tandem and walk-behind rollers, BM-series cold milling machines, BMP and BW trench compactors, and BPR reversible vibratory plates — making part number 05548305 one of the most broadly applied hydraulic fittings in the Bomag lineup. Ordering the correct OEM part ensures a proper hydraulic seal and connection geometry matched to the original system design.

Key Features

• Genuine OEM Hydraulic Sealing — manufactured to Bomag's original material and dimensional standards, ensuring the angular seat forms a leak-free connection under operating pressure
• Correct Flange Angle and Port Geometry — the angled flange orientation matches the original routing and port alignment exactly, allowing this fitting to bolt into place without reworking hydraulic lines
• Broad Cross-Equipment Coverage — fits BF-series pavers, BW tandem and walk-behind rollers, BM cold milling machines, BMP and BW trench compactors, and BPR 75/60 D-3 and BPR 75/60 HD-3 reversible vibratory plates
• Hydraulic Circuit Integrity — a properly seated angular flange union maintains full system pressure and flow; a worn, cracked, or improperly fitted union causes hydraulic fluid loss, pressure drop, and risk of machine shutdown
• Direct OEM Replacement — part number 05548305 cross-references directly to the original assembly, eliminating guesswork when ordering for service or scheduled maintenance

An angular flange union is a hydraulic fitting that connects two fluid lines at a fixed angle, allowing circuit designers to route hoses and pipes cleanly around structural members without bending or stressing the lines themselves. The flange mounting distributes clamping force evenly around the port face, creating a robust, vibration-resistant seal that is especially important on compaction and milling equipment where constant mechanical vibration is present. When this fitting develops a leak or the sealing face is damaged, hydraulic pressure in the connected circuit drops, reducing actuator force or drive performance and potentially causing hydraulic fluid contamination of surrounding components.
