O-Ring kits are the most widely used elastomer in sealing applications. Made from a copolymer of butadiene and acrylonitrile, NBR oring are highly regarded for their excellent mechanical properties, including outstanding resistance to oils, fuels, and other petroleum-based fluids. These properties make them the default choice for a wide range of applications, especially in hydraulic and pneumatic systems.

FKM (Fluorocarbon) o ring kit are widely used in industries where performance under extreme conditions is critical, such as aerospace, automotive, and chemical processing. FKM rubber has excellent resistance to heat, ozone, oxygen, mineral oils, synthetic hydraulic fluids, fuels, and many organic solvents, making it the first choice for sealing solutions in harsh environments.

NQKSF offering a wide range of standard and custom NBR o ring kits and FKM o-ring kits. See our size chart for sizes.
