The Bomag 05742003 O-Ring is a genuine OEM sealing component designed for Bomag BF 300-series pavers, BW-series tandem rollers, BW-series single drum rollers, and BW 11 RH-5 pneumatic tyred rollers. As an authentic Bomag part, this O-Ring is manufactured to the same material and dimensional standards as the original, ensuring a reliable hydraulic or fluid seal within the specific assembly it serves. Compatible machines include the BF 300 P, BF 300 C, BW 154 AD-5, BW 141 AD-5, BW 151 AD-5, BW 145 D-5, BW 177 D-5, and related variants across the BF 300 and BW families. When a worn or damaged O-Ring is the source of a fluid leak, replacing it with the correct genuine part number 05742003 restores the integrity of the sealed connection without guesswork.
Key Features
- Genuine OEM Sealing Material — manufactured to Bomag's original compound and durometer specifications, delivering the compression resistance needed to maintain a leak-free seal in hydraulic and fluid circuits
- Direct Drop-In Replacement — dimensionally identical to the original, this O-Ring seats fully in its groove and mates to mating surfaces without modification or fitting adjustment
- Broad Bomag Fitment — fits a wide range of Bomag equipment including BF 300 P and BF 300 C pavers, BW 154, BW 151, and BW 141 tandem rollers, BW 145 and BW 177 single drum rollers, and the BW 11 RH-5 pneumatic tyred roller
- Leak Prevention Where It Counts — a correctly seated O-Ring keeps hydraulic fluid, lubricant, or coolant contained, preventing pressure loss and protecting surrounding components from contamination or heat damage
- Fluid System Integrity — using the correct OEM O-Ring in fuel or hydraulic circuits is essential; an incorrect compound can swell, crack, or harden under pressure and temperature cycles, creating dangerous leak points
An O-Ring is a circular elastomeric seal installed in a machined groove between two mating surfaces or fittings. Its job is to deform slightly under compression and fill any gap between those surfaces, creating a barrier that prevents fluid or gas from escaping a pressurized circuit. On Bomag pavers, tandem rollers, single drum rollers, and pneumatic tyred rollers, O-Rings appear throughout hydraulic systems, engine assemblies, and fluid passages — making them small but critical components. When an O-Ring degrades, hardens, or is cut during reassembly, the result is a visible external leak or internal bypass that starves downstream components of pressure, leading to erratic machine behavior or accelerated wear on pumps and motors.
