If you have searched for a Polaris part and found it listed under Zodiac, or a Jandy number that turns up as Fluidra, you have run into one of the pool industry's more tangled corporate histories.

Same part, different badge
Zodiac acquired Jandy and Polaris. Fluidra then merged with Zodiac. The result is a single parts catalogue wearing four names, and part numbers that cross freely between them — R-prefixed numbers in particular.
Shaft seal listed for Polaris, Jandy, Zodiac, Fluidra and Hayward is a good example: a single seal listed against several brands because it genuinely fits all of them.
Common items
The R0586300 Tri-Lobe seal for Nature2 Fusion and Vision Pro is another that appears under Jandy, Zodiac and Fluidra simultaneously — and note it is an FKM part, because it sits in a chemical feeder. See why feeder seals need FKM.
Practical advice
Search the number, not the brand. If a listing shows your part number under a different badge in the same group, it is the right part. When in doubt, send us the number and the equipment model.
Before you reassemble

Seat every o-ring with a thin film of food-grade silicone. Dry rings pinch and take a set. Aqua Flex Food Grade Silicone Lubricant is what ships in our kits.
O-rings only. Never lubricate the polished faces of a mechanical shaft seal.
