Looking for a dependable sealing solution that can handle tough industrial applications? These Buna-N O-rings are engineered to provide reliable performance in a wide variety of environments where secure fluid containment is crucial.
Manufactured from high-quality Buna-nitrile rubber, these O-rings feature a 70A durometer rating that provides an optimal balance between flexibility and rigidity. This hardness level ensures the rings can maintain their shape under pressure while still conforming to mating surfaces for an effective seal. The material offers impressive tensile strength and exceptional resistance to abrasion, tearing, and compression set, making these rings perfect for applications where mechanical stress is a concern.
These O-rings perform reliably across an extensive temperature range, from -30°F (-34°C) up to 250°F (121°C). This broad thermal capability makes them suitable for both cold storage environments and high-temperature industrial processes. The Buna-nitrile formulation provides excellent compatibility with petroleum-based fluids, HFA/HFB/HFC hydraulic fluids, vegetable oil, alcohol, acids, and aliphatic hydrocarbons. Note: They should not be used with acetone, ethers, esters, ozone, or in applications with UV light exposure.
Whether you're maintaining equipment in automotive repair shops, industrial facilities, or hydraulic systems, these O-rings meet Aerospace Standard AS568A specifications for consistent quality. The pack of two ensures you have replacements ready when needed. Their 8" inside diameter, 8-1/2" outside diameter, and 1/4" width make them ideal for standard sealing applications in engines, faucets, flanges, valves, and various cylindrical components.
These rings are designed to provide long-lasting sealing performance in demanding conditions, helping prevent leaks and maintain system efficiency. Their circular cross-section creates a uniform seal between overlapping mating surfaces, ensuring reliable pressure containment for your critical applications.
