COMPATIBILITY & APPLICATIONS
FOS Series Filter Housing Seal
This Buna-N gasket is engineered as a direct replacement seal for Shelco FOS Series filter housings. Buna-N offers excellent resistance to water, mild acids, and petroleum-based fluids, making it suitable for municipal water treatment, industrial process filtration, and aquatic applications where temperatures remain below 250°F. Regular gasket replacement during routine maintenance ensures housing integrity and prevents contamination from bypass or external leakage. Always inspect gaskets for compression set, cracking, or wear during cartridge changeouts.
💧 Replace housing gaskets at every third cartridge change or annually, whichever comes first, to maintain proper seal integrity and prevent costly system downtime from leaks.
