Part number 90-423-5360 (also known as O-330, 805-0360, or AS568 #360) is a generic Buna-N O-ring with a 5-7/8" inner diameter and 3/16" cross-section.
It is a very common seal used for the lids/volutes of various pumps, filters, and leaf traps in both pool and spa equipment.
The O-ring is used in components from major suppliers, and thus many hot tub manufacturers use this part in their spas:
Waterway Plastics: This O-ring (Waterway part #805-0360) is commonly used for their top-load filter lid assemblies.
Pentair (American Products/Sta-Rite/Rainbow): Used in the lid and volute of various pumps and filters, including the Dura-Glas Pump, Max-E-Glas Pump, Microstar Clear, RDC Series, and RTL Series top-load filters.
Cal Spas: Uses the Waterway or Pentair components that require this specific O-ring, sometimes referencing it with their own internal number (similar to 500-2510 or 5010 Cal Spa Special).
Coast Spas: Uses this O-ring (O-330) in specific pressure-type filter canisters.
Hayward: The O-ring is used in the lid of their W530/W540/W560 series leaf canisters.
Hydropool: Directly lists this generic O-ring as a replacement part on their website for use in their systems.
Jacuzzi / Carvin: Used in specific models of pumps and filters from these brands.
This O-ring is a highly standardized part found in filter and pump components across a wide spectrum of the hot tub and pool industry.
