The Bomag 05815701 Seal Kit is a genuine OEM component designed for BW 120 AD and BW 138 AC tandem rollers, as well as BW 1050 T, BW 850 TR, and BW 85 T trench compactors. As a factory-sourced assembly, this seal kit matches the original specifications for material grade, geometry, and compression characteristics — so it installs correctly the first time without guesswork. Verified fitment spans the full range of compatible machines listed above, making part number 05815701 the right call when a hydraulic or fluid-circuit seal service is due.
Key Features
- Genuine OEM Sealing Materials — sourced directly from Bomag, this kit uses the same compound grades and durometer ratings as the original seals, maintaining proper compression and fluid retention across the service life of the assembly
- Complete Kit Format — all seals needed for the service interval are included in one package, so technicians can complete the job without hunting down individual components separately
- Direct-Fit Replacement — profiles and dimensions match the original housings exactly, allowing straightforward installation into the hydraulic or fluid-circuit assembly without modification
- Broad Confirmed Fitment — verified for the BW 120 AD and BW 138 AC tandem rollers and the BW 1050 T, BW 850 TR, and BW 85 T trench compactors, covering both equipment classes in a single part number
- Leak Prevention at the Source — worn or hardened seals allow fluid to bypass, causing pressure loss, contamination, and accelerated wear on surrounding components; replacing them with this kit restores a proper fluid barrier
- Fluid-System Safety Compliance — hydraulic leaks on compaction equipment create slip and fire hazards on the jobsite; using the correct OEM seal kit ensures the system meets original pressure-retention requirements
A seal kit contains the complete set of elastomeric rings, lip seals, and gaskets required to restore fluid-tight integrity to a hydraulic or fluid-circuit assembly. Seals degrade over time through heat cycling, pressure fluctuation, and chemical exposure, eventually hardening or cracking and allowing fluid to escape past mating surfaces. When seals fail, the machine loses hydraulic pressure, fluid contaminates surrounding components, and continued operation risks damage to pumps, cylinders, or motors — making timely seal replacement one of the most cost-effective preventive maintenance tasks on any compaction machine.
