APC APCC7688 85 Sq Ft Spa Filter Cartridge
Clean water, sharper pleats, longer runs.
The APC APCC7688 is an 85 square foot pleated replacement cartridge built to drop straight into Diamante Spas and U.S. Tooling filter housings. It crosses directly to Unicel 8CH-852, Pleatco PUST80-F2M, and Filbur FC-0518, so if your old element carries any of those numbers, the APCC7688 is a one-for-one fit. You get 85 square feet of reinforced polyester media on a rigid PVC core, a closed handle top for easy lift-out, and a standard 2 inch MPT bottom that threads right onto the manifold.
Why PST Customers Pick This
Exact 8CH-852 Replacement
Matches the Unicel 8CH-852, Pleatco PUST80-F2M, and Filbur FC-0518 footprint exactly. Same 8 inch diameter, same 12-3/4 inch length, same 2 inch threaded base, so it seats and seals like the original.
85 Sq Ft Of Surface
A full 85 square feet of pleated media gives your pump less restriction and your water more contact area, which means stronger flow between cleanings and fewer pressure spikes during heavy bather loads.
Reinforced Polyester Media
The pleats are spun-bonded polyester that rinses clean under a hose and holds its shape soak after soak. It traps fine debris, body oils, and scale without the fuzzing you see on cheaper paper elements.
Rigid PVC Core
A molded PVC center core resists collapse under suction so the cartridge keeps its round profile and even pleat spacing through hundreds of filter cycles. No deforming, no channeling.
Closed Handle Top
The injection molded top handle lets you lift the element out of a deep canister with one hand, even when it is wet. The closed top also forces all flow through the media instead of bypassing it.
Standard 2" MPT Base
An open 2 inch male pipe thread bottom mates with the standard Diamante and U.S. Tooling manifold ports. No adapters, no shimming, just thread it down and you are filtering.

Frequently Asked Questions
Will the APCC7688 replace my Unicel 8CH-852 or Pleatco PUST80-F2M?
Yes. The APCC7688 is a direct, one-for-one replacement for the Unicel 8CH-852, Pleatco PUST80-F2M, and Filbur FC-0518. It shares the same 8 inch diameter, 12-3/4 inch length, closed handle top, and 2 inch MPT bottom, so it drops into the same housing with no modification.
What size pump and spa does this 85 sq ft cartridge fit?
This element is sized for Diamante Spas and U.S. Tooling filter canisters that take an 8 by 12-3/4 inch cartridge. The 85 square feet of media suits typical residential spa pumps. If your current cartridge measures 8 inches across, about 12-3/4 inches tall, and has a threaded bottom, this is your part.
How often should I replace it, and can I just clean it instead?
Rinse the pleats with a garden hose every two to four weeks and deep soak it in a cartridge cleaner whenever flow drops. Most polyester elements last 12 to 24 months with that care. Replace it once the pleats stay gray after cleaning, the fabric tears, or the end caps separate.
Can I install this cartridge myself?
Yes. Shut off the pump, relieve pressure, open the canister lid, lift the old cartridge out by the handle, and thread the APCC7688 down onto the 2 inch MPT port until snug. Reseat the lid, restart the pump, and check for the normal clean pressure reading. No tools or plumbing changes are required.

Let customers speak for us
Loved how fast it got here. It has small wiring and I was glad it was in a protective envelope and it arrived without breaking.
just as listed. well packeged, fast ahip, works fine. purchased to remedy issue with heater and ozone injectorboth operating together. might have been able to just bend old switch a bit but did not try that.
Great customer service and knowledge of product. Asked of compatibility and they had the answer. My intouch2 was not working so I researched new intouch3 from Spa Dealer and they wanted $75 just to come out, then $125 for up to an hr...just to confirm what I already knew. Contacted PST and they had the product and confirmed compatibility. Saved me some $$.Thanks PST.
