Description
Overview:
The Hydraulic Sealing Washer 3/8" BSP Bonded Rubber Centre is a bonded-seal washer designed to stop leaks on straight-thread hydraulic fittings and banjo bolts. It combines a rigid metal outer ring with a bonded rubber centre that compresses to create a secure face seal as the joint is tightened. Sized for 3/8 inch BSP threads (approx. 9.5 mm nominal bore), it is suited to use under bolt heads, adaptors, plugs, and hose tails on pumps, valves, cylinders, and manifolds. Built for demanding environments, it helps maintain system pressure and prevents weeps at static joints, keeping machinery efficient and clean. Durable construction supports reliable service in plant, agricultural, and industrial equipment. Manufacturer Part Number: 968 380.
Key Features:
- 3/8" BSP size (approx. 9.5 mm) for common hydraulic ports and banjo bolts
- Bonded rubber centre with a rigid metal washer for dependable flat-face sealing
