PSH - Great Giant Pre-filter Polycarbonate Lid - 4080311R

PSH – Great Giant Pre-filter Polycarbonate Lid

This is the genuine PSH replacement polycarbonate lid (cover) for the Great Giant series pre-filter, identified as position 66 in the official PSH exploded-view diagram. It provides a clear, durable seal over the pre-filter housing, allowing visual inspection of the basket without disassembly and protecting the internals from contamination. Sold individually as a direct OEM spare part.

Compatibility

Designed exclusively for the PSH Giant-series pre-filters, including the Great Giant pre-filter range. The Giant series is PSH’s high-flow commercial pump line built for public pools, saltwater pools, and aquariums. Always cross-reference the exploded-view reference (position 66) against your specific pre-filter model before ordering to ensure correct fitment.

Why Genuine Matters

The polycarbonate lid must form a pressure-tight seal with the pre-filter body to prevent air ingress and maintain pump prime. A genuine PSH lid guarantees the correct thread pitch, wall thickness, and material grade — polycarbonate offers superior impact resistance and long-term UV stability compared to generic alternatives — ensuring reliable performance in demanding commercial installations.

Installation

Replacement is straightforward: depressurise the system, unscrew the existing lid (wing-nut or threaded depending on variant), inspect the lid O-ring or gasket (sold separately), fit the new lid and hand-tighten firmly. Professional installation is recommended for commercial or high-pressure systems to ensure proper torque and system integrity.
