- Automotive A/C HNBR Assortment – 200 Pieces / 12 Sizes Includes 200 green HNBR O-rings in 12 commonly used AS568 sizes for automotive air conditioning and sealing repairs.
- Premium HNBR (HSN) Material for R-134a Systems Made from highly saturated nitrile (HNBR/HSN) 70 durometer, engineered for excellent resistance to R-134a refrigerant and the synthetic compressor oils used in modern A/C systems.
- High-Temperature & Ozone Resistance vs Standard NBR HNBR provides greater thermal stability, tensile strength, wear/extrusion resistance, and improved resistance to ozone and oxygen compared to standard Buna-N.
- Wide Service Temperature Range Reliable sealing from -40°F to +300°F, allowing long-term performance in high-heat engine bays and pressure-cycling A/C circuits.
- Organized Case for Fast Service Work Seals arrive sorted in a labeled organizer case, making it easy to grab the correct size during A/C line, fitting, and compressor service.
