S-90130A140 0.99" ID x 2" OD Rubber Sealing Washers

Key Features & Benefits at a Glance

• Superior sealing performance with EPDM rubber construction that maintains integrity under compression
• Excellent temperature resistance from -20°F to 212°F for reliable operation in extreme environments
• Optimal hardness (Durometer 55A) provides perfect balance between sealing force and material flexibility
• Weatherproof and corrosion-resistant properties ensure long-term durability in outdoor and harsh conditions
• Precise dimensional compatibility with 1" screw size (0.99" ID) for secure fit and effective sealing
• Environmentally compliant with RoHS 3 standards for safe use in regulated industries
• Consistent thickness range (0.110-0.140") ensures uniform compression and reliable sealing performance

Professional Applications & Engineering Value

These EPDM rubber flat washers deliver exceptional sealing performance in demanding industrial environments where temperature fluctuations and exposure to elements compromise ordinary washers. The 2" OD x 0.99" ID dimensions provide optimal surface coverage for 1" screw size applications, creating reliable seals in plumbing systems, HVAC installations, and industrial equipment. The Durometer 55A hardness ensures sufficient compression without permanent deformation, while the EPDM material maintains flexibility across the entire temperature range from -20°F to 212°F. This combination addresses common failure points in weatherproof sealing applications where thermal cycling and environmental exposure typically degrade performance, making these washers ideal for corrosion-resistant solutions in construction, manufacturing, and maintenance operations.
