Bonded EPDM washer engineered for superior sealing performance in demanding applications. The 6.0mm inner diameter and 25mm outer diameter provide optimal coverage for medium-duty fastening tasks. EPDM bonding ensures excellent resistance to weathering, UV exposure, and chemical degradation, making it ideal for outdoor installations and industrial environments. The elastomeric seal maintains integrity across a wide temperature range, preventing leakage and corrosion around fastener points. Essential for plumbing, HVAC, and electrical installations where reliable waterproofing is critical.
