Product details

The Sta-Rite 178745Z is the genuine 12.5 in. tank lid for the Posi-Clear RP cartridge filter in the 150 and 200 sq ft sizes. A lid that has cracked from sun and pressure, or whose sealing edge has worn, will weep at the clamp or fail to hold pressure. This replaces it with the same Pentair part the filter came with.

What you get

The lid alone. The tank o-ring, air relief valve and pressure gauge are separate parts, and it is worth checking each while the filter is open.

Fit

Made for the Posi-Clear RP 150 and 200 sq ft models. Measure your existing lid at 12.5 in. to confirm before ordering.
