Seals should be replaced if a leak occurs, if seals become pinched or cut, or every two years. 2. Sealing surfaces should be cleaned of any contamination or old lubricant. 3. The new O-ring and gasket should be lubricated with silicone grease before installation. This makes it much easier to assemble and disassemble the filter housing.
