uxcell 10Pcs AS-225 O-Rings, EPDM O-Rings 1-7/8" ID, 3-21/32" OD, 1/8" W

Key features

• Package Contains: The package includes 10 pcs of AS-225 O-rings, sized with 1-7/8" inner diameter, 3-21/32" outer diameter, and 1/8" width. (Please confirm the size and material before placing your order.)
• Durable Material: These O-rings are crafted from EPDM, delivering excellent resistance to ozone, weathering, water, steam, and a wide range of polar chemicals and mildly corrosive media. They maintain flexibility while ensuring a tight seal, resisting deformation or cracking even under long-term use
• Reliable Performance: The uniform circular cross-section design ensures even pressure distribution, and with a durometer of 70, these O-rings provide excellent flexibility and sealing performance for medium-pressure applications. The operating temperature range of -40°C to 120°C (-40°F to 248°F) makes them suitable for both cold and hot environments
• Easy to Install: Clean the mounting surface, then smoothly fit the O-ring into the groove without twisting or overstretching. Lubricants (such as silicone grease) are recommended to extend service life. After installation, check that the sealing surface is fully seated
• Versatile Applications: These 70 durometer EPDM O-rings are suitable for sealing applications requiring excellent weather and chemical resistance. They are widely used in automotive cooling systems, potable water installations, HVAC equipment, electrical enclosures, and outdoor industrial assemblies, such as radiator connections, pump housings, coolant lines, weatherproof junction boxes, and solar thermal system seals
