This bag of 100 black Dowty washers is intended for use with M6 fasteners. The washers are designed to create a reliable seal in pipework, mechanical joints, and hydraulic assemblies, reducing the risk of fluid leakage where bolts or fittings are installed.
On site, these washers are fitted between the fastening head and the adjoining surface. Their construction, featuring a metal ring with an elastomer insert, delivers a secure seal when compressed, making them well suited for locations subject to vibration or movement.
