Bomag 05742825 O-Ring

The Bomag 05742825 O-Ring is a genuine OEM sealing component designed for a wide range of Bomag tandem rollers, single drum rollers, pneumatic tyred rollers, and pavers — including BW 141 AD-5, BW 151 AD-5, BW 154 AD-5, BW 145 D-5, BW 177 D-5, BW 177 DH-5, BW 11 RH-5, BF 300 C-2 S340-2 TV, BF 300 P-2 S340-2 TV, and BF200C 2 models, among others. Sourced directly from Bomag, this O-Ring meets the same material and dimensional standards as the original, ensuring a dependable seal every time. If your machine is showing signs of fluid weeping, hydraulic seepage, or pressure loss, replacing the O-Ring with part number 05742825 is the correct, factory-sourced fix.

Key Features

• Genuine OEM Sealing Material — manufactured to Bomag's original compound and durometer specifications, so the O-Ring maintains its compression set resistance across operating temperatures and pressures
• Drop-In Dimensional Match — molded to the exact cross-section and inner diameter of the original, so this O-Ring seats cleanly in its groove without shimming or modification
• Broad Bomag Fitment — confirmed for BW-series tandem rollers (including BW 141 AD-5, BW 151 AD-5, BW 151 AC-5, BW 154 AD-5, BW 154 AP-4i, and BW 154 AP-4i AM), single drum rollers (BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, BW 177BVC-5, and PL variants), BW 11 RH-5 pneumatic tyred rollers, and BF-series pavers (BF 300 C-2 S340-2 TV, BF 300 C-2 S340-2 V, BF 300 P-2 S340-2 TV, BF 300 P-2 S340-2 V, and BF200C 2)
• Leak Prevention at the Source — a correctly seated O-Ring maintains hydraulic or fluid circuit integrity, preventing pressure loss that can cause erratic compaction performance or paving inconsistencies
• Fuel and Hydraulic System Safety — a failed O-Ring in a fuel or hydraulic line creates a fire and environmental hazard; replacing it promptly with the correct OEM part restores safe, contained operation

An O-Ring is a circular elastomeric seal fitted into a machined groove between two mating surfaces or around a port, valve, or fitting. Its job is to prevent fluid — whether hydraulic oil, fuel, or coolant — from escaping the circuit under pressure. When an O-Ring ages, hardens, or is nicked during assembly, it loses its ability to conform to the groove walls and leaks begin. Left unaddressed, even a small leak can starve a hydraulic system of pressure, contaminate surrounding components, or create a safety hazard on the machine. Replacing a worn O-Ring with the correct Bomag part number 05742825 restores the seal to its original condition quickly and at minimal cost.
