EPDM, a synthetic rubber, is known for its excellent resistance to heat, ozone, and numerous chemicals, making it an ideal material for manufacturing washers used in fastening systems. The addition of a washer to a fastener significantly enhances its functionality by distributing the load evenly, preventing damage to the mating surfaces, and ensuring a tight seal. The EPDM washer, with its resilient nature, adds an extra layer of protection against leaks and environmental ingress.
