Description
Overview:
The 3/8" BSP Bonded Seals - supplied in a pack of 100 - are used to create a reliable, leak-tight face seal on BSP fittings in hydraulic and pneumatic circuits. Each seal combines a rigid metal washer with a vulcanised rubber insert that deforms slightly under bolt or fitting load to close off potential leak paths. This gives a secure seal without over‐compression, helping protect threads and components. Suitable for construction and garden machinery, from excavators and loaders to mowers and compact tractors, these washers help maintain hose ends, adapters, and manifold connections. Size: 3/8" BSP (approximately 9.5 mm nominal). They are a practical choice for workshop maintenance and on-site repairs where consistent sealing performance and quick fitting matter.
Key Features:
- 3/8" BSP size (approximately 9.5 mm nominal) for common UK hydraulic and pneumatic fittings
- Bonded design with metal carrier and vulcanised elastomer insert for controlled compression and sealing
- Helps achieve leak-proof joints on flat-faced ports, banjo bolts, and adapters
- Suitable for high-pressure service when used with correctly matched BSP fittings
- Easy to fit: place under the fastener head or against the port face and tighten to the manufacturer's torque
- Reduces the risk of over-torquing compared with plain washers and fibre gaskets
- Resistant to common hydraulic oils and typical workshop conditions
- Consistent quality across a bulk pack of 100 for efficient stocking and repeat repairs
- Supports reliable maintenance routines on construction plant and garden machinery
- Cost-effective alternative to sealing compounds where a mechanical seal is preferred
Typical Applications:
Sealing BSPP/BSPT hose tails, adapters, banjo fittings, and manifold ports on hydraulic rams, pumps, valve blocks, power packs, and air systems. Commonly used on diggers, skid steers, telehandlers, compressors, log splitters, ride-on mowers, and compact tractors to prevent fluid leaks and maintain system pressure.
Also known as:
Bonded washers, BSP bonded sealing washers, captive seal washers, Dowty-type washers, metal-rubber sealing washers for BSP fittings, hydraulic sealing washers.
