Bomag 05542191 L-Union

The Bomag 05542191 L-Union is a genuine OEM hydraulic fitting designed for an exceptionally wide range of Bomag equipment, including BF-series pavers, BM-series cold milling machines, BW-series rollers, BC-series compactors, BPR and BPH reversible vibratory plates, and RS and MPH recycler/stabilizers. As a direct-sourced OEM component, this L-Union is manufactured to Bomag's exact specifications, ensuring the correct thread form, port angle, and pressure rating for each application. Confirmed fitment spans models including the BF 600 P-3 S 500, BM 1000/35, BW 213 D-3, BC 772 RB, and BPR 75/60 D-3, among many others. When a hydraulic fitting fails or begins to seep, replacing it promptly with part number 05542191 keeps fluid circuits sealed and operating pressures stable across the machine.

Key Features

• OEM Hydraulic Integrity — Manufactured to Bomag's exact thread pitch, port angle, and pressure specification, so the fitting seats and seals correctly without improvisation.
• Angled Port Design — The 90-degree L-profile routes hydraulic lines in tight or obstructed spaces, allowing clean hose routing without sharp bends or stress on adjacent fittings.
• Direct-Replacement Fit — Threads straight into the original port; no adapters, thread chasing, or rework needed to mate with existing hydraulic lines.
• Broad Multi-Machine Coverage — Confirmed fitment across Bomag pavers, cold milling machines, single drum rollers, tandem rollers, pneumatic tyred rollers, refuse and landfill compactors, soil compactors, reversible vibratory plates, and recycler/stabilizers — including the BF 300 C, BM 2000/60, BW 177 DH-3, BC 672 RB, and RS 500.
• Leak-Free System Pressure — A correctly seated L-Union maintains full hydraulic circuit pressure; a worn or cross-threaded fitting causes fluid loss, pressure drop, and potential system damage across affected circuits.

An L-Union is an angled hydraulic union fitting — typically bent at 90 degrees — used to connect two hydraulic lines or a line to a component port where a straight fitting would conflict with surrounding structure or require an awkward hose bend. By redirecting flow at a precise angle, the fitting protects hose integrity, reduces stress at connection points, and allows compact hydraulic routing inside crowded equipment housings. When this fitting corrodes, cross-threads, or begins to weep fluid, system pressure drops and contamination risk rises, making timely replacement with a correctly specified part essential for uninterrupted hydraulic performance.
