I would buy this again!

This adapter solved my problem and allowed me to get everything hooked back up before we got hit with a decent snowfall. The tech guys were great to deal with and helped me get the right parts to finish my repairs.

Worked perfectly

Old pump wet end had 2 1/2"" threads (as well as the Unions) - this allowed me to hook up the existing plumbing to my new 2"" pump's threaded wet end.

ordered a new wet end for my spa. the person on the other end informed me to order an adapter that I did not know about so everything would fit correctly. The tech support was second to none. He stayed on the line and talked me through the install.

Adaptor was a perfect fit and solved my problem. Just wish I had figured out I needed it before I started my project. Added a few additional days to get my hot tub back up and running again.

Spa Depot recommended this thread adapter. Without it my spa wouldn't have worked. These guys were able to look at my pictures and made outstanding recommendations.

Worked perfect, good quality gasket

Used it to fit a different used pump on my tub. Saved me $100 from buying a new pump!

Just what I needed

This adapter was just what I needed to for the input side of my pump. For some reason my input is 1/2 an inch bigger than the output. I emailed customer service and told them what my problem was and they send me the link for this adapter which worked perfectly.
