Aladdin G-359 Square Cut Ring Gasket Lid Seal

Product Description

The ALADDIN G-359 is a square cut ring gasket designed to seal pump lids and strainer basket housings in pool and spa circulation equipment. This O-ring style lid seal maintains a watertight barrier between the pump housing and its lid, preventing air leaks that can disrupt prime and reduce system efficiency. Pool service technicians and equipment installers rely on replacement gaskets like the G-359 to restore proper sealing after a lid seal has become worn, cracked, or compressed beyond its serviceable range.

The G-359 is suited for use in residential and light commercial pool and spa systems where strainer pot lids or pump lids require a square cut ring seal. It is a direct OEM-style replacement part intended for routine maintenance and service calls. Pool technicians typically keep lid gaskets on hand as a standard service item given how frequently these seals require replacement during seasonal startups and equipment inspections.

Key Features

• Square cut ring profile provides consistent sealing contact around the lid perimeter
• Designed as an OEM-style replacement for pool pump and strainer housing lid applications
• Compact form factor fits standard strainer pot and pump lid grooves
• Resists degradation from chlorinated and chemically treated pool water

Compatibility

Designed as an OEM-style replacement lid gasket for pool pump strainer housings and basket pot lids in residential and light commercial pool and spa equipment.

Installation Notes

Installation should be performed by a qualified pool equipment technician. Before replacing the lid gasket, shut off the pump and relieve any system pressure by opening the air relief valve on the filter. Remove the old gasket, clean the lid groove of debris and old lubricant, then seat the new G-359 gasket evenly in the groove. Apply a thin coat of silicone-based pool gasket lubricant before reassembling the lid to extend seal life and prevent binding.
