PACETAP 1 1/2" SAE Thread Screw in Spa Hot Tub Filter Replacement 2 Pack Compatible with Pleatco PWW50P3, for Unicel 6CH-940, for Filbur FC-0359, for Waterways 817-0050, for Viking spa Filter

As measured from the outside of the threads, this filter is actually 1 7/8” across (not the 1 1/2” shown in the image). Yes, it’s probably considered a 1 1/2” SAE course thread fitting, but the image with the measuring lines is misleading. In our case, that’s a GOOD thing that it’s larger, since we’ve been trying to find a filter to fit our Platinum Spas Barcelona hot tub. This is a tiny bit shorter in height but works fine. So far so good in terms of it being a filter!

Fit my Viking spa perfectly for less than half of what the hot tub store in my town charges.

Great filter of a fraction of the cost of oem filters. Appears to be well made.

Great fit for our hot tub! Easy to clean works like expected

works as it should, no issues

The thread pattern has changed and no longer will fit my hot tub. Worthless.

Showed up on time, intact and exactly as advertised. I have bought these twice now and appreciate that they are in stock and easy to order.

I can’t seem to get the right size! I’ve ordered 2 different sizes Ava still it didn’t fit!
