Product Description

The Sealey 250 Piece Copper Sealing Washer Assortment provides a comprehensive selection of metric copper washers for plumbing, automotive and hydraulic applications. This workshop-essential assortment includes 16 different sizes ranging from 5mm to 20mm internal diameter, offering tradespeople and mechanics immediate access to commonly required copper sealing washers without the need to source individual sizes. Copper sealing washers are valued for their superior sealing properties and resistance to high temperatures, making them ideal for fuel systems, brake lines, hydraulic connections and plumbing fittings. The malleable nature of copper allows these washers to conform to mating surfaces, creating reliable fluid-tight seals that resist vibration and thermal cycling. The assortment arrives in a partitioned storage box that keeps each size organised and readily identifiable in the workshop or van. With 250 pieces in total, this Sealey AB020CW washer set provides sufficient stock for both routine maintenance tasks and emergency repairs across automotive, plumbing and general engineering applications.
