The Bomag 05740188 O-Ring is a genuine OEM sealing component designed for Bomag tandem rollers including the BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 131 ACW-2, BW 131 AD-2, and BW 80 ADS. Sourced directly from Bomag, this O-Ring is manufactured to the exact material compound, durometer, and dimensional tolerances of the original — ensuring a leak-free seal in the assembly it serves. When a worn or damaged O-Ring allows fluid or air to bypass the seal, it can compromise system pressure and lead to broader mechanical issues; replacing it with part number 05740188 restores the integrity of the sealing joint without modification.
Key Features
- OEM Material Specification — manufactured to the exact compound hardness and dimensional tolerances Bomag specifies for this sealing application, not a generic approximation
- Drop-In Seal Replacement — sized to seat correctly in the original groove without stretching, trimming, or adaptation
- Broad Tandem Roller Coverage — fits BW 80 AD-2, BW 80 ADS, BW 90 AD-2, BW 100 ADM-2, BW 131 ACW-2, and BW 131 AD-2 tandem rollers
- Leak Prevention — a correctly seated O-Ring maintains system pressure and prevents fluid ingress or egress that can damage surrounding components
- Genuine Bomag Part — supplied as authentic OEM, so the part number, cross-reference, and fitment records match Bomag's own service documentation exactly
An O-Ring is a precision loop of elastomeric material that creates a fluid- or air-tight seal between two mating surfaces or within a bore. In compaction equipment like Bomag tandem rollers, O-Rings appear throughout hydraulic circuits, water systems, and mechanical assemblies, where they prevent pressurized fluid from escaping a joint and contaminants from entering it. When an O-Ring degrades — through heat cycling, compression set, or chemical exposure — it loses its ability to seal effectively, resulting in leaks, pressure loss, and potential damage to the components it was protecting. Replacing a failed O-Ring promptly with the correct part keeps the surrounding assembly performing as intended.
