Specialist Material Washers 

Advanced Seals & Gaskets Ltd specialise in non-metallic washers, offering a massive choice of materials from the popular sponge, rubber and plastics, right through to specialist material washers for use within many industries.  The quality of the cut and finish of the washer is just as important as the material used, therefore we ensure our in-house manufacturing team follow our customer’s drawings or samples to create an exact match – from a one-off sample to multi-thousand runs, we have a machine to quickly and accurately produce perfectly formed washers in a range of sizes, these include a number of presses and CNC machines.


What are Specialist Material Washers?

Washers are a flat ring (comprising of an Outer Diameter (OD), Internal Diameter (ID) and the thickness) cut from a sheet or roll of material,  which is placed between two surfaces creating a level surface, acting as a spacer or between a nut/bolt to spread the pressure when tightenedMost of the materials we offer can be cut and used to convert into washers, whether it’s for sealing against harmful chemicals or to fill a gap avoiding the ingress of dust, we have a range of material types to choose from.


Material Types 

Other materials from which we can produce washers include a number of specialist types, these can include:

Leather is a material historically used as a sealing material. It is flexible, resilient and can withstand high levels of manipulation making it suitable for hydraulic gaskets, pipeline and air pump seals, etc. When prepared correctly, leather can be resistant to water, oil, salts, grease and detergents.

Post Office Sponge (orange open cell sponge) washers are resistant to ozone, oils, acids and alkaline.  This open cell sponge is designed to be absorbent and often used in packaging, labelling or other wet applications.

Abrasion Resistant Polyurethane washers are manufactured from one of the toughest and wear/abrasion-resistant materials on offer. This material has excellent electrical insulation properties, and resistance to high impact, weather, oil and petrol.
