Product overview

C-7350 is an aftermarket pleated hot tub filter cartridge, 7 in. in diameter and 10-3/4 in. long, with 50 sq ft of filter area. Top: semi-circular handle. Bottom: open (2-11/16" ID). Center opening: 2-11/16 in.

It interchanges with Pleatco PCD50N and Filbur FC-3963.

OEM cartridges it replaces: Caldera 1019401, 73532.

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.

Sourcing questions

What OEM numbers does C-7350 replace?

POOLPOINT C-7350 is an aftermarket replacement cross-referenced to 1019401, 73532, FC-3963 and PCD50N. Those numbers identify fitment only — the part is manufactured by POOLPOINT, not by Unicel.

Is C-7350 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 C-7350?

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.
