The Bal Seal provides consistently low friction for more than 1 million cycles to meet demanding PM requirements. Precision-machined from PTFE or polyethylene materials, our seal is compatible with the wide variety of solvents and buffers used in (U)HPLC equipment. The seal’s Bal Spring energizer, with its individual canted coils, provides consistent force that promotes even wear, prolongs service life, and minimizes flow path contamination.
