(DISCONTINUED BY MANUFACTURER)

SEE REPLACEMENT PART: OBSOLETE

The AquaStar Gasket [2-3/8" ID x 3-7/16" OD] is used to help seal a connection point, cover, lens, housing, tank, or equipment interface where water-tight performance is required. A worn or flattened gasket can lead to leaks, air intrusion, pressure loss, or improper equipment operation, making replacement an important part of routine service. Match the gasket by part number, dimensions, shape, and application rather than appearance alone, since similar gaskets may have different thicknesses or profiles. Clean mating surfaces before installation and avoid pinching or over-tightening so the new seal can seat correctly. Key details from the item listing include 2-3/8" ID x 3-7/16" OD. Manufacturer or brand reference: ProStar by AquaStar. Part number: 20GASKET.
