The Pentair IntelliFlo VS Drive Gasket is built for maintenance situations where matching the existing component can help avoid extra downtime. It is used for seal replacement and leak-prevention service and should be selected when the original part no longer performs as expected. This sealing component is used when an existing gasket or O-ring has flattened, cracked, swollen, or begun allowing water or air leaks. A fresh seal can help restore proper compression between mating parts, support more consistent equipment operation, and reduce nuisance leaks that often appear after routine service. Always clean the sealing surface and verify the original shape and size before installation. Before ordering, compare the part number 350108, visible shape, connection style, and model information with the component being replaced. This helps reduce returns, prevents mismatched repairs, and gives the installer a better starting point for restoring normal operation. Replacement sealing part for the specific equipment or valve family listed in the title. Helps reduce leaks by restoring compression between mating surfaces. Recommended when the old seal is flattened, brittle, stretched, cut, or swollen. Clean the sealing groove and mating surfaces before reassembly. Compare shape, size, and part number with the existing seal before ordering.
