Description
Overview:
This 100-pack of 1/4" BSP bonded seals is a practical sealing solution for hydraulic, plumbing, and pneumatic connections. Each seal combines a metal washer with a bonded elastomer lip that compresses under bolt or fitting torque to create a reliable, leak-tight joint on flat-faced ports and under banjo bolts. Suitable for use on plant, agricultural equipment, compressors, pressure washers, and general workshop machinery, they help prevent fluid loss and contamination. The size suits 1/4" BSP threads (approximately 13.16 mm outside diameter; 19 TPI), with 1/4 inch equal to 6.35 mm as a nominal reference. Designed for use with straight or parallel threads, these seals are often preferred over plain copper washers where consistent, repeatable sealing is needed.
Key Features:
- Bonded metal-and-elastomer washer design delivers a dependable, low-leak seal on flat faces
- Suits 1/4" BSP fittings (approx. 13.16 mm OD; 19 TPI), common across hydraulic and pneumatic systems
- Pack of 100 provides ample stock for service kits, maintenance vans, and site repairs
- Helps prevent leaks under vibration and thermal cycling when correctly installed and torqued
- Works well beneath banjo bolts, adaptors, test points, and BSPP port fittings
- Typically compatible with hydraulic oils, diesel, air, and water-based fluids (check elastomer compatibility)
- Clean, easy fitment with no sealant required on the sealing faces
- Consistent performance on machined flat surfaces, even where minor surface marks exist
- Useful upgrade over plain fibre or copper washers for repeatable assembly results
- Generally replaced at each service or disturbance to maintain sealing reliability
Typical Applications:
Sealing hose tails, adaptors, and banjo fittings on excavators, loaders, tractors, forklifts, compressors, and pressure washers. Common around pumps, valves, cylinders, manifolds, test points, and filter heads in hydraulic and pneumatic circuits. Suitable for workshop plumbing tasks using BSP connections where a flat-face seal is required.
Also known as:
Rubber-to-metal sealing washers, hydraulic seal washers, BSP port sealing washers, banjo bolt sealing washers, metal-backed elastomer washers, flat-face sealing washers, parallel thread sealing washers.
