This part fit perfectly onto my Spa. I was able to connect it without any problems. I have a Sundance Spa Tacoma model, but these are universal and should fit most spas. No leaks after installing them.

I am not well versed on hot tub repair. This appeared to be a fairly universal part. Came fast and worked. My vacation rental lost just one hot tub fee, so speed and accuracy was the ticket.

Worked well on the repair. Will buy again. Use a hair dryer to warm the flex tube, this will allow you to spin the nut on. Some petroleum jelly worked well on the threads too.
