American Spa PartsJacuzzi Premium Hot Tub Retrofit 5 1/4" Jet Gray Power Pro Video How to

The direction suggests a resource fit ring glued to the fitting. If your jet is good all you need to do is remove the center white spinning part via two small tabs. Then re insert the new white plastic spinning part from the back and put back in the tub. All good no modification needed.

I ordered these jets to update my 2004 Jacuzzi J325 premium hot tub to the new style jets. The white glue in rings were too large to fit into my existing jet space. I purchased the jacuzzi brand jets for half the cost of these knock offs and they fit perfectly.

This fit my hot tub but I didn't think I would have to empty tub and glue it in. I will install it on the next drain and clean.

Terrible does not fit what it says.very disappointed in Amazon

Delivered quickly and it fits and functions perfectly!
