ProAqua Spa Filter PWW50L 4CH-949 FC-0172

ProAqua hot tub filter is a compatible replacement for the Pleatco PWW50L, Unicel 4CH-949 and Filbur FC-0172.

Details:

• Diameter: 5.0"
• Length: 13 1/16" (does not include handle)
• Top Hole: Handle
• Bottom Hole: 1-1/2" FEMALE SAE Threaded (threads measure slightly larger inside diameter)
• Brand: Pro Aqua by Magnum Filters

Please note:
Unicel and Pleatco brands of this filter use threads on the bottom that are inside a raised hole. The ProAqua filters have a new design for the bottom made with stronger ABS plastic, which leads to a more rigid filter and requires less threads to seat properly. The new ABS plastic ends are designed to last longer under the harsh conditions of spa water and though it looks a bit different is cross compatible with the older style threaded PWW50L and 4CH-949 filters. See below for close up of the new style threaded bottom.
