Product details

The Pentair 39010200Z is the genuine tank o-ring for the Clean and Clear Plus cartridge filters, the Nautilus FNS Plus DE filters and the American Products RPM filters, both the Titan RPM DE and the Quantum RPM cartridge. It measures 20-7/8 in. across the inside with a 7/16 in. cross section.

What it does

The o-ring sits in the joint between the two tank halves under the clamp. Every time the tank is opened to clean cartridges or grids, that seal is disturbed, and an o-ring that has flattened, cracked or stretched will weep at the seam once the system is back under pressure.

Before you order

Measure the old ring if you can: 20-7/8 in. inside diameter and 7/16 in. thick. This is the OEM Pentair part; a generic in the same size is also available if you would rather not pay for the name.
