PSH - Giant Series Pre-filter Lid Gasket (Pack of 2) - 4001310R

PSH – Giant Series Pre-filter Lid Gasket (Pack of 2)

This is a genuine PSH replacement lid gasket designed to maintain a watertight seal between the transparent cover and the body of PSH Giant-series pre-filters. Supplied as a pack of two, it is the correct spare for exploded-view position 65 and is an essential consumable for any routine pre-filter service. Replacing a worn or damaged gasket promptly prevents air ingestion, pressure loss, and potential pump damage.

Compatibility

These lid gaskets are specified for the full PSH Giant pre-filter range, including the Small Giant and Great Giant models used in commercial and high-flow pool installations. Always cross-reference your pre-filter model and exploded-view diagram (position 65) before ordering to confirm fitment. This part is not intended for PSH pre-filter families outside the Giant series.

Why Genuine Matters

Genuine PSH gaskets are manufactured to the exact material specification and profile of the original, ensuring a reliable compression seal against the pre-filter lid. Third-party seals may differ in hardness, cross-section, or chemical resistance, risking leaks or premature failure in pool-chemical environments. Choosing an authentic PSH part protects your equipment warranty and keeps your filtration system running at full efficiency.

Installation

Before fitting, clean the lid groove and seating face thoroughly to remove any debris, old seal material, or scale. Seat each new gasket evenly in the groove without stretching, then close the lid finger-tight using the stainless-steel wing nuts in a cross pattern to ensure uniform compression. No tools or lubricants are required for a standard gasket swap, though a pool-safe silicone grease may be applied sparingly to aid seating and extend service life.
