PSH - Diffuser Gasket for Micro Pool Pump (Pack of 25) - 4054810R

PSH – Diffuser Gasket for Micro Pool Pump (Pack of 25)

This is a genuine PSH replacement diffuser gasket (exploded-view position 60) designed specifically for the PSH Micro pool pump. It seals the joint between the diffuser and the pump body, preventing air ingress at this critical interface and ensuring the pump maintains prime and delivers consistent water flow.

Why This Gasket Matters

A worn or compressed diffuser gasket is a leading cause of chronic loss of prime in pool pumps — air is drawn in through the failed seal faster than the impeller can sustain vacuum, resulting in reduced flow and pump strain. Replacing this gasket with a genuine PSH part restores the airtight seal between the Noryl fiberglass-reinforced diffuser and the polypropylene pump body, returning the Micro pump to full performance.

Compatibility

This gasket is a direct OEM fit for the PSH Micro pool pump range — a self-priming centrifugal pump designed for small, removable, and spa-type pools, available in 0.25, 0.33, and 0.50 HP variants. Always cross-reference the exploded-view diagram (position 60) with your specific pump serial number before fitting, particularly for units manufactured before 2015.

Installation

Replacement is straightforward: disassemble the pump, remove the diffuser from the motor assembly, slip off the old gasket, seat the new one firmly to the stop, and apply a thin coat of approved lubricant before reassembling. Sold in a trade pack of 25 pieces, this product is ideal for service technicians and pool professionals carrying out planned maintenance across multiple units.
