Check Valve Replacement Cartridges

OPTI-MAX® enables customers to perform check valve repair much more rapidly and reliably than with OEM rebuild kits. The same OPTI-MAX check valve cartridge can function in both inlet and outlet positions. Also, the same cartridge will work in multiple types/brands of HPLC systems, when used with the correct OPTI-MAX housing. Most OPTI-MAX check valve housings utilize our unique Free-Turn® two-piece swivel design which allows the check valve cartridge to be replaced without having to disconnect tubing from the housing. Should you need to outfit your pump with an OPTI-MAX housing, for the first time, please visit the Instrument Replacement Parts section of our website to find the correct housing + cartridge configuration for your pump.
