Product details
The Jandy R0405200 is the tank retaining ring, the clamping ring that holds a filter tank closed. It is the genuine Jandy part.
What it does
A filter tank is built in two halves with a seal between them. The retaining ring draws those halves together and keeps that seal compressed against operating pressure. Everything the filter does depends on that joint staying closed, which makes the ring one of the few filter parts that is genuinely safety relevant.
Checking the fit
This ring is carried under the Jandy DEV series DE filters, models DEV48 and DEV60. Jandy uses rings of similar appearance across several filter families, so confirm R0405200 against the parts breakdown for your specific filter rather than going by look.
When to replace
Replace a ring that is cracked, distorted, badly corroded, or whose hardware has stripped. Do not try to compensate by overtightening. While the tank is open, look at the tank seal as well, because a fresh ring will not stop a leak caused by a tired o-ring.
