Description
Overview:
The Seal Bonded Washer 1/2" BSP (12.7 mm BSP) is a genuine Altrad/Belle component designed to provide a secure, leak‐tight seal on pipe and hydraulic fittings. Built for demanding site conditions, it combines a rigid steel washer with a bonded elastomer sealing lip to stop fluid leaks at the joint face. This reliable sealing washer is commonly used on Belle floor saws and other construction machinery where hydraulic or fuel connections must remain leak-free under vibration and load. It is a direct match for 1/2" BSP fittings and is a suitable replacement for machines such as the Belle Compact X and Duo 350X. Using a genuine part helps maintain correct fit, performance, and service life.
