Pentair Locking Ring Assembly 59052900Z

The Pentair 59052900Z is the locking ring assembly that clamps the lid to the tank on Pentair Clean & Clear and American Products Predator cartridge filters, and on the Pentair EasyClean D.E. filter system. When the ring cracks, strips or will not hold pressure, this is the genuine replacement.

Size

The ring measures 12 in. inside diameter, 13 1/4 in. outside diameter and 2 1/4 in. high. Measure the ring on your filter before ordering. Pentair has used more than one ring size across the Clean & Clear line, and this one belongs to the filters that share the Predator and EasyClean tank.

While it is off

The tank body o-ring (AMP-051-1246) sits under this ring. If it is flattened or has taken a set, replace it at the same time so the seam seals when the new ring is tightened down.
