Premium Material - Made of Buna-N (Nitrile) rubber, offering excellent resistance to oils, fuels, hydrocarbons, and industrial fluids like ammonia or Freon. Durable Hardness - 70A Durometer provides optimal balance of flexibility and penetration resistance for long-lasting seals. Precision Dimensions - 2" Inner Diameter (ID), 2-1/4" Outer Diameter (OD), and 1/8" Cross-Section (Width) ensure perfect fit for cylindrical surfaces. Wide Temperature Range - Performs reliably in extreme conditions from -40°F/-40°C to 248°F/120°C. Versatile Seal - Round cross-section design creates effective pressure sealing for hydraulic, pneumatic, and industrial applications. This 226-size Buna-N O-Ring (Pack of 10) is engineered for professional-grade sealing performance. The nitrile rubber construction delivers superior compatibility with petroleum-based fluids, solvents, and gases while maintaining elasticity across a broad temperature spectrum. Its standardized AS568-226 sizing (2" ID x 2-1/4" OD x 1/8" width) makes it ideal for maintenance, manufacturing, and automotive applications where leak-proof sealing is critical. The 70A durometer rating ensures durable compression resistance without sacrificing conformability. Each O-ring undergoes quality inspection to meet industrial standards for dimensional accuracy and material integrity.
