Bomag 05542195 L-Union

The Bomag 05542195 L-Union is a genuine OEM hydraulic fitting designed for an exceptionally broad range of Bomag equipment, including BF-series pavers, BW-series single drum rollers, tandem rollers, and pneumatic tyred rollers, BC-series refuse/landfill compactors and soil compactors, BM-series cold milling machines, MPH/RS/BS-series recyclers and stabilizers, and BMP trench compactors. Sourced directly from Bomag, this L-Union matches the original component in thread specification, angle, and port geometry — no improvised adapters, no mismatched fittings. It is the correct replacement for part number 05542195 across every machine in its fitment list, giving technicians confidence that the hydraulic connection will seat and seal exactly as the factory intended.

Key Features

• Genuine OEM Hydraulic Fitment — Manufactured to Bomag's own thread form, port angle, and material specification, so the L-Union maintains rated pressure integrity across the full range of operating conditions.
• Angled Port Routing — The 90-degree union body routes hydraulic lines cleanly around obstructions in tight machine bays, connecting directly to factory hose and port interfaces without rerouting or adapting.
• Broad Cross-Fleet Coverage — A single part number 05542195 covers pavers including BF 300, BF 600, BF 700, BF 800, and BF 900 variants, BW-series tandem and single drum rollers, BC refuse/landfill and soil compactors, BM cold milling machines, MPH, RS, and BS recyclers/stabilizers, BMP 851 trench compactors, BW 850 TR and BW 85 T trench compactors, and the BP 50/55 HE vibratory plate.
• Leak-Free Hydraulic Integrity — A correctly installed L-Union maintains system pressure and prevents hydraulic fluid loss; a failed or worn fitting causes pressure drop, contamination risk, and loss of hydraulic function in actuators and drives dependent on that circuit.
• Direct OEM Replacement — As a genuine Bomag part, this L-Union carries the same part number referenced in Bomag service documentation, so technicians can cross-reference it against workshop manuals with confidence.

An L-Union is an angled hydraulic fitting — typically formed at 90 degrees — that connects two hydraulic lines or ports while changing the direction of flow to suit the routing constraints of a machine's hydraulic circuit. In construction equipment like pavers, rollers, and milling machines, hydraulic circuits power everything from drum drive heating, steering, and auxiliary functions, so every fitting in that circuit must maintain a leak-free seal under sustained pressure and vibration. When an L-Union fails — through thread damage, seal degradation, or corrosion — hydraulic fluid loss reduces system pressure and can cause erratic or complete loss of function in the affected circuit, making prompt replacement with a correctly specified part essential to keeping the machine operational and safe.
