Good To Know

Q: Should I apply lubricant to this diaphragm gasket during installation? A: Yes, applying a thin layer of silicone-based pool gasket lubricant helps seal the connection and prevents the rubber from pinching during assembly.

Q: What are signs that my filter gasket needs to be replaced? A: Common symptoms include pool water leaking from the filter housing flange, a drop in overall pool pressure, or DE powder returning back into the pool.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
