Syringe O-Ring Replacements

Made with a copolymer of butadiene and acrylonitrile, the Chemyx Buna-N/Nitrile/NBR seals offer compression-set resistance and are designed to resist most oils, lubricants, and hydrocarbon fuels. Our most popular replacement syringe pump seals, the Buna-N syringe O-ring replacements, are effective from -22°F to 250°F (-30°C to 121°C), offer superior abrasion and tear resistance, and are best for heavy-duty industrial applications, for use with and sized according to our Chemyx Stainless-Steel Syringes.
