uxcell 5Pcs AS-249 O-Rings, Nitrile Rubber O-Rings 4-7/8" ID, 5-1/8" OD, 1/8" Width Round Sealing Gasket for Automotive Machine Plumbing Sealing Repair (70 Durometer, Black)

• 5pcs NBR O-rings, 4-7/8" ID, 5-1/8" OD, 1/8" Width
• Durable Material: These O-rings are crafted from high-elasticity nitrile rubber, delivering excellent wear resistance along with resistance to oils, acids, 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 -20°C to 80°C (-4°F to 176°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 nitrile rubber O-rings are suitable for low to medium pressure sealing applications and are widely used for sealing in pipelines, industrial equipment, food processing, automotive systems, and low-pressure hydraulic systems, such as pump covers, compressor housings, instrument housings, and coolant/air conditioning lines
