More features

• Package Contains: 100pcs NBR O-rings, 3/8" ID, 9/16" OD, 3/32" Width
• Durable Material: These O-rings are made of high-elasticity nitrile rubber, offering excellent wear resistance. 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 90, they withstand high loads and exhibit outstanding extrusion resistance. 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: Suitable for high-pressure environments such as hydraulic systems, pneumatic tools, fuel injection systems, and compressors. Commonly used in injection molding machines, automotive braking systems, and industrial valve sealing applications
