Bonded EPDM washer engineered for superior sealing performance in demanding applications. The 6.0mm inner diameter and 25mm outer diameter provide optimal load distribution while the elastomeric EPDM material resists oils, weathering, and temperature fluctuations from -40°C to +120°C. Ideal for plumbing, HVAC, and industrial installations where reliable waterproofing is essential. Delivers consistent compression set retention and maintains integrity under sustained pressure, ensuring long-term leak prevention across diverse environmental conditions.
