The Bomag 05742569 Sealing Washer is a genuine OEM sealing washer designed for Bomag BW 174, BW 161, BW 190, and BW 202 series tandem rollers. Sourced directly from Bomag, this component matches the original specification installed on these machines at the factory. This sealing washer is confirmed to fit the BW 174 AP-4, BW 174 AP-4 AM, BW 174 AP-4 PB, BW 174 AP-4 AM PB, BW 174 AP-4i, BW 174 AP-4i AM, BW 174 APO-4i, BW 174 ACP 4I AM, BW 161 AD-5, BW 161 AC-5, BW 161 ADO-5, BW 190 AD-5, BW 190 ADO-5, and BW 202 AD-5 tandem rollers. When a sealing washer fails, even minor fluid leaks can lead to contamination, pressure loss, and accelerated wear on surrounding components — replacing it with a genuine OEM part keeps the system tight and operating as intended.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material and dimensional specification, ensuring the correct crush and sealing performance for hydraulic and fluid connections on these tandem rollers
- Drop-In Replacement — designed to seat and torque exactly as the original, with no trimming, shimming, or adaptation needed at the connection point
- Broad BW-Series Coverage — fits the full range of BW 174, BW 161, BW 190, and BW 202 tandem roller variants, including AP-4, AP-4i, AD-5, AC-5, ADO-5, PB, and AM configurations
- Leak Prevention at the Source — a correctly fitted sealing washer maintains system pressure and keeps fluid where it belongs, protecting pumps, valves, and downstream hydraulic components from contamination
- Correct Part Number Confidence — ordering by part number 05742569 ensures you receive the exact washer specified for these machines, eliminating guesswork on size, material, and thread compatibility
A sealing washer creates a fluid-tight seal at bolted or threaded connection points in hydraulic, fuel, or fluid lines. It deforms slightly under torque to fill any microscopic gaps between mating surfaces, preventing leaks under operating pressure. When a sealing washer wears, cracks, or is reused past its service life, it loses that deformation capacity and allows fluid to seep past the joint — leading to pressure loss, external contamination, and potential damage to surrounding components. Replacing it with a properly specified genuine OEM washer restores the seal to its original integrity.
