Description
Overview:
The 1/8"-1" BSP Bonded Seals Assorted Box (100 pieces) is a mixed set of dowty type sealing washers for creating reliable, pressure-tight joints on BSP threaded fittings. Each seal combines a steel outer washer with a bonded rubber centre to provide a consistent, compressible sealing lip. This design helps prevent fluid leaks on hydraulic, pneumatic, and plumbing connections commonly found on plant, agricultural machinery, pressure washers, pumps, and workshop equipment. The assortment covers the most-used BSP sizes from 1/8 inch (approx. 3.2 mm) up to 1 inch (25.4 mm), making it suitable for maintenance, repairs, and installations. Supplied under MPN 105 143, it offers a practical selection for hose ends, adaptors, banjo bolts, valve blocks, and manifold ports.
