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, 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.
Key Features:
- 3/8" BSP size for common hydraulic ports and banjo bolts
- Bonded rubber centre with a rigid metal washer for dependable flat-face sealing
- Helps prevent fluid loss and air ingress in high-pressure hydraulic connections
- Quick to fit: sits under the fitting head; no sealant tape or paste usually required
- Compatible with typical mineral oil-based hydraulic fluids
- Metal support ring reduces rubber extrusion when clamped correctly
- Tolerates minor surface imperfections on mating faces for consistent sealing
- Compact, low-profile design to suit tight spaces around manifolds and valve blocks
Typical Applications:
Sealing face joints on BSP hydraulic fittings, including hose tails to manifolds, banjo bolts on pumps and cylinders, and adaptor plugs on valve blocks and reservoirs. Common across construction plant, materials handling equipment, compact tractors, log splitters, presses, and workshop hydraulic tools where reliable, leak-free connections are required.
