Description
Filbur PC1976 Pool Filter Cartridge, 7 in x 20 in, 80 Sq Ft
Crystal clear water, pleat after pleat.
The Filbur PC1976 (FC-1976) is an 80 square foot replacement filter cartridge that drops straight into the Pentair Clean & Clear Plus 320 and Waterway Crystal Water 325, four cartridges to a tank. It cross-references the Unicel C-7470, Pleatco PCC80, and Pentair R173573, so if any of those numbers are stamped on your old element, this is your replacement. You get reinforced PVC center cores and antimicrobial polyurethane end caps built to ride out years of salt and chlorine.
Why PST Customers Pick This
80 Sq Ft of Media
Roughly 170 deep pleats of spunbonded polyester give you the full 80 square feet of surface area, so the cartridge traps more debris and runs longer between cleanings.
Direct CCP320 Fit
Sized at 7 in by 20-1/16 in with 3 in open end caps to seat correctly in the Pentair Clean & Clear Plus 320 and Waterway Crystal Water 325 manifolds.
Antimicrobial End Caps
Reinforced polyurethane end caps resist bacteria growth and shrug off deterioration from salt and chlorinated water far better than bargain cartridges.
Reinforced PVC Core
A rigid PVC center core keeps the pleats from collapsing under flow, holding the filtration area open the way it was designed to run.
No-Tool Swap
Open the filter, lift the old element off the manifold, drop the PC1976 on, and reseat. No adapters, no proprietary hardware, no special tools.
Cross-Reference Match
Replaces Unicel C-7470, Pleatco PCC80, Pentair R173573, Waterway 817-0106, and Darlly 70804, one part number to memorize for the next reorder.

Frequently Asked Questions
How many PC1976 cartridges does my filter take?
The Pentair Clean & Clear Plus 320 and the Waterway Crystal Water 325 both use a set of four 80 sq ft cartridges to reach their full 320 sq ft rating. Replace all four at the same time so the set loads evenly and you do not leave one tired element dragging down the whole tank.
Will this replace my Unicel C-7470 or Pleatco PCC80?
Yes. The PC1976 is a direct cross-reference for the Unicel C-7470, Pleatco PCC80, Pentair R173573, Waterway 817-0106, and Darlly 70804. Same 7 in by 20-1/16 in body and 3 in open end caps, so it seats on the same manifold.
What pool filters does the PC1976 fit?
It is built for the Pentair Clean & Clear Plus 320 (CCP320), Waterway Crystal Water 325, and matching PacFab clamp-style cartridge tanks rated at 320 sq ft total. If your tank holds four cartridges and the old element measures 7 in across with 3 in open ends, this is the right one.
How do I know when to replace it?
Swap the cartridges when a fresh chemical clean no longer drops the filter pressure back to its clean baseline, or when the pleats are matted, frayed, or no longer spring back. As a rule of thumb, plan on a new set every two to three seasons depending on bather load and how often you rinse them.
Can I install it myself?
Yes. Shut the pump off, bleed the filter air relief to zero pressure, open the tank, lift the old cartridges off the bottom manifold, set the new PC1976 elements onto the same manifold posts, reseat the top, and reassemble. No tools or fittings required beyond what came with the filter.
