Hello Mike, the end caps are easy to locate on the www. If you are going to do the replacement of endcaps. Do replace both endcaps due to inner gasket fatigue becoming brittle from heat and chemicals. The price for the set will be over $200. The lifetime of a heater assembly is rated at around 4 years. I replaced the small endcaps only to have the large end failed a month later due to brittle gaskets. Backyardplus.com 805.541.9000

Trouble shooting found the small end cap with a sizable housing crack plus brittle rubber gaskets. This Watkins 240V6KW heater has been functioning fine new since 2013. I can find replacement endcaps and rubber gaskets for both ends for over $120. The heater ohms out 10 ohms. Should I gamble just replacing the rubber gaskets and endcaps or bring a new heater into the game at $250. I am going with the new heater.

Today I noticed a leak occurring on Jetsetter spa after being away for a week. Lifted spa cover to find water level has dropped below filter gate. Removed side panel to exposed power and heater. Found water leaking from the smaller, double barrel end cap of the 240V6KW heater assembly. I will see what I can do for repairs but I do like your style.
