Description
Overview:
The 3/4" BSP Hydraulic Sealing Washer (MPN 968 340) is a bonded seal designed for reliable, leak-free joints in hydraulic systems. It consists of a rigid metal washer with a bonded rubber centre that compresses under torque to create a positive seal at the connection face. Sized for 3/4 inch BSP fittings (19.05 mm), it is suitable for use across plant, agricultural and industrial hydraulics, including excavators, loaders, tractors, log splitters, compressors and hydraulic power packs. The washer helps maintain system pressure and fluid integrity by preventing seepage at static joints, especially where BSP parallel threads rely on face sealing. It is a practical, cost-effective part for routine maintenance and repairs by tradespeople and DIY users who need dependable sealing performance.
Key Features:
- 3/4" BSP size (19.05 mm) for standard British Standard Pipe parallel fittings
- Bonded rubber centre compresses to form a secure, uniform seal
- Metal backing ring supports the rubber insert to resist extrusion under load
- Helps prevent fluid loss and pressure drop at static face joints
- Suitable for common hydraulic oils and typical workshop environments
- Simple to fit: place between mating faces and tighten to specified torque
- Aids vibration resistance compared with plain copper or fibre washers
- Useful for banjo bolts, adapters and BSPP port connections
- Compact, flat form factor for tight spaces and easy storage
- Supports efficient maintenance routines and reduces rework from leaks
Typical Applications:
Used to seal flat-face joints on 3/4" BSP (19.05 mm) hydraulic connections in plant machinery, farm equipment, material handling machines, industrial presses and mobile hydraulic systems. Common at hose adapters, valve blocks, pumps, cylinders and banjo fittings where dependable face sealing is required to prevent leaks and maintain operating pressure.
