Product overview
4CH-24 is an aftermarket pleated hot tub filter cartridge, 4-5/8 in. in diameter and 9-3/4 in. long, with 25 sq ft of filter area. Top: molded cone handle. Bottom: 1-1/2" male thread/MPT.
It interchanges with Pleatco PGS25P4 and Filbur FC-0131.
OEM cartridges it replaces: Saratoga Spas 20254-238.
Fitment notes: Dream Maker Spas: Remove "pad adaptor" (if present) from skimmer before threading MPT directly into suction fitting. Replaces any cartridge that has an MPT fitting or a 1.9" id w/ disposable adapter.
Before ordering, measure the old cartridge — overall length, outside diameter and both end fittings. Some catalogs quote the length of threaded top-load cartridges with the thread and some without, so a quarter-inch difference between listings is common. We supply spa service companies, dealers and online retailers: MOQ 50 pcs per part, mixed cartons welcome, and single samples to confirm fit before a production order.

What OEM numbers does 4CH-24 replace?
POOLPOINT 4CH-24 is an aftermarket replacement cross-referenced to 20254-238, FC-0131, FC-0131-SC and PGS25P4. Those numbers identify fitment only — the part is manufactured by POOLPOINT, not by Unicel.
Is 4CH-24 a genuine Unicel part?
No. POOLPOINT manufactures compatible aftermarket replacement parts. We are not affiliated with, sponsored by or endorsed by Unicel; the brand name and OEM numbers are used to identify fitment only.
What is the minimum order quantity for 4CH-24?
MOQ is 50 pcs per part, and mixed cartons are welcome to reach the order minimum. Samples are a separate case — we supply single pieces so you can confirm fitment before committing to a production run.
