End Cap, Heater 2 Barrel 78077, black

fixed the leak without having to buy a whole new unit at £400. however it need some additional tightening with a g clamp.

Great price great fit did the job very well very pleased.

Fit my hot tub heater perfect.

Saved me a $1500 hottub repair bill with these parts .. fit perfect, bit of a pain to get at the screws but is what it is.

This product was a perfect replacement for the cracked one on my spa. Fit was perfect and instructions were more than adequate. I spent more time taking off stuff that was blocking my access to the heating unit, than I did replacing the cracked unit. But after it was replaced, my spa has worked perfectly, without leaking one drop of water.

So my spa heater was leaking very, very slowly. I took a picture and sent to the spa company who said likely a heater replacement! Well, it seemed that all I needed was a new cap and washer kit. So glad I found this and the fix itself is really easy. The cap and washers fit like a glove on my Caldera spa!! Very happy.
