Our soft annealed Copper Crush Washers are ideal for sealing steel or stainless steel brake unions. Both the fitting and mating port must have adequately large flat sealing surfaces to ensure a reliable seal. This 10mm size has a slightly smaller OD and is thicker than our standard 3241-3/8 washer. It can be used with either 10mm or 3/8" fittings.
Sold individually.
