Description
Overview:
This Seal Bonded 1/8" BSP is a genuine Altrad/Belle OEM sealing washer designed for leak-free hydraulic joints on compactors and trench rammers. Built as a bonded seal (steel washer with a moulded elastomer lip, typically nitrile rubber), it provides a reliable static seal under bolt heads and hydraulic adaptors. The 1/8" BSP size (approx. 3.18 mm nominal designation) suits common BSP hydraulic fittings used on site machinery. It is engineered for demanding use on equipment such as the RTX Trench Rammer and Bulldog Power Pack, helping to maintain system pressure and reduce fluid loss. Durable materials and accurate dimensions allow consistent performance during vibration and temperature changes. Manufacturer Part Number (MPN): 5/0018.
