Product details
The Pentair 152516Z is the buttress thread closure o-ring for Triton II side mount sand filters. It is the genuine Pentair part and is also listed as 152516.
Where it sits
The closure threads into the top of the Triton II tank, and this ring is what seals it. A buttress thread carries load in one direction, which suits a pressure vessel, but the thread does not make the seal on its own. That job belongs to the o-ring.
When to replace it
Rubber hardens, flattens and takes a set. Once it does, the closure starts to weep under pressure no matter how firmly it is tightened. Clean the groove and the sealing face, fit a fresh ring with a light coat of silicone o-ring lubricant, and the leak goes away.
