Description
Overview:
The 1/8"-1" BSP Bonded Seals Assorted Box (65 pieces) is a workshop kit of one-piece sealing washers for British Standard Pipe fittings. Each bonded seal combines a metal backing washer with a bonded rubber sealing lip to create a reliable face seal under bolt heads, banjo bolts, adaptors and plugs. Used widely on hydraulic and plumbing circuits, they help prevent leaks at high and low pressures without extra sealant. This compact set covers common BSP sizes for maintenance and repair on plant, agricultural machinery, pressure washers, compressors, generators and general industrial equipment. The organised box makes it easy to select the right size on site, reducing downtime and improving the quality of pipework and hose connections.
