"Does anyone know what this is called so I can find a replacement?"
Look up the manufacturer and model on the Internet and then look for a parts diagram to identify the parts. There are several hot tub dealers in the metro area.
Or you could just JB Weld the split and give it a try.....
And be sure to run plenty of disinfectant through the hot tub before jumping into a used one.....
no telling what has been festering in the tub and lines.......
I looked at the manufacturers website and they dont list the part. I would have to buy the whole unit for $300. I plastic welded the inside and epoxied the outside. Its probably the strongest part on the tub now.
My EDC: Handcuffs, Bandana, and Ball Gag.
If I'm ever at a party and the cops come to arrest people. Ill blindfold myself, throw the ball gag in, handcuff my hands, and hide in a closet. Police never arrest hostages!
