DOWTY WASHER 1/8BSP 10.4*15.9*2

A Dowty washer, also known as a bonded seal, is a sealing washer consisting of a metal outer ring bonded to an inner rubber sealing element. When compressed by a bolt or fitting, the rubber deforms to create a reliable, pressure-tight seal. The metal ring prevents over-compression, ensuring consistent sealing performance and extended service life. Dowty washers are widely used where fluids, oils, or gases must be contained under pressure.
