The following are O-ring sizes that are used with Chemyx Stainless Steel syringes. The Chemyx O-rings are made with a copolymer of butadiene and acrylonitrile, the Buna-N/Nitrile/NBR seals offer compression-set resistance and are designed to resist most oils, lubricants, and hydrocarbon fuels.
Our most popular syringe pump seals, the Buna-N, 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.
To learn more about Chemical Compatibility, we have prepared a guide for common syringe assemblies. These are only general guidelines; we recommend checking online resources to confirm compatibility with your specific media. The following is a thorough chemical compatibility resource here.
O-rings made with any material with the following inner and outer diameters can be used with Chemyx Stainless Steel syringes.
