Product overview
4CH-949 is an aftermarket pleated hot tub filter cartridge, 4-15/16 in. in diameter and 13-1/2 in. long, with 50 sq ft of filter area. Top: v-groove semi-circular handle. Bottom: 2" female SAE thread.
It interchanges with Pleatco PWW50L and Filbur FC-0172.
OEM cartridges it replaces: Waterway 817-4050.
Fitment notes: For use on 1-1/2" male SAE stand pipe. Master Spas: Replacement for 5" OD Eco-Pur filtration systems; must verify OAL for correct Unicel replacement. Replacement for Rising Dragon, Waterway, Custom Molded Products.
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-949 replace?
POOLPOINT 4CH-949 is an aftermarket replacement cross-referenced to 817-4050, FC-0172 and PWW50L. Those numbers identify fitment only — the part is manufactured by POOLPOINT, not by Unicel.
Is 4CH-949 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-949?
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.
