What are Sealing Washers (Shim Washers or Rubber Penny Washers)?

Situated underneath a nut, a joint or an axle bearing the purpose of a Sealing Washer is to soften rubbing, spread pressure, keep components apart, and prevent leakage or stop unfastening. To stop vibration from spreading or to ensure that a seal is stable a rubber compound may be the best solution for the application.

Sealing Washers are ideal for surfaces coated with paint, plating or enamel and suitable for use with water, mineral base oils and alkalis, or over a temperature range of -10°C to +80°C. Washers for screwed assemblies offer up to 200 lbf/in2 working pressure.

Sealing Washers are extensively used in Automotive & Motor, Water & Pump, Engineering, MRO, and Manufacturing Industries and are particularly useful on sumps, gearboxes, axles and drain plugs.

Examples of the production process:

• Heat Treatments: Hardening and tempering for alloy steels, annealing for copper, brass, aluminium, and brazing.
• Machine Processes: Blanking, bending, stamping, deep drawing, tapping.
• Finishes: Tumble finishing, deburring, polishing, assembly, packaging.

Some speciality Sealing Washers are certified by FDA, EC1935/2004 & EC2023/2006, WRC, WRAS, USP Class VI, 3-A 18-03 Sanitary Standards and KTW.
