Product details

The Pentair Rainbow R172214 is the locking ring that holds the lid on several pieces of Pentair equipment. It threads down over the lid to clamp it against the body and o-ring, and it is the part that gets cracked or stripped from years of opening and closing.

Fits

Pentair Rainbow HC-3315, HC-3330 and 3340 high capacity chemical feeders, Pentair Dynamic Series II cartridge filters, the Predator II inline cartridge filter and the Kreepy Krauly 179 leaf trap.

While you are in there

A ring that will not seal is often a tired lid o-ring rather than the ring itself. The lid o-ring and lock spring are separate parts, and it is worth checking both before reassembling.
