The Bomag 05541746 Union is a genuine OEM component designed for Bomag BW 12 R pneumatic tyred rollers and BW 170 AP AM, BW 174 AP, BW 174 ACP, BW 174 ACP-AM, and BW 174 AP-AM tandem rollers. Sourced directly from Bomag, this union delivers an exact match to the original specification, ensuring a correct, trouble-free installation without modification. When a union wears or fails, fluid or hydraulic circuit integrity is compromised — replacing it with a verified OEM part restores proper system function and protects connected components from damage.
Key Features
- OEM-Grade Sealing Integrity — manufactured to Bomag's original tolerances, ensuring the connection maintains full pressure without leaks across the fluid or hydraulic circuit
- Direct-Replacement Fit — threads and dimensions match the original installation point exactly, dropping in without reworking ports or adjacent fittings
- Broad Roller Coverage — confirmed fit across BW 12 R pneumatic tyred rollers and the BW 174 AP, BW 174 ACP, BW 174 ACP-AM, BW 174 AP-AM, and BW 170 AP AM tandem roller lineup
- Protects System Components — a correctly seated union prevents pressure loss that can stress seals, hoses, and downstream components, extending the service life of the surrounding circuit
- Verified Part Number Traceability — ordering by Bomag part number 05541746 confirms you receive the correct union for your specific machine, eliminating guesswork at installation
A union is a threaded fitting used to join two sections of pipe, hose, or hydraulic line in a way that allows the connection to be separated and reassembled without disturbing the rest of the circuit. On compaction rollers, unions appear in hydraulic, fuel, and cooling plumbing where serviceability is required — they hold the system under pressure while allowing straightforward disassembly during maintenance or repair. When a union corrodes, cracks, or develops thread damage, it introduces leaks that degrade system pressure and can lead to fluid loss, overheating, or hydraulic failure, making timely replacement essential to keeping the roller operating at full capacity.
