Pair of Heater Seals
Made by Balboa
(1 Pair Genuine Balboa Heater Seals)
Seals for hot tub heaters: Balboa, Hydroquip, Gecko amongst many other brands and makes.
These seals have a ridge on both sides, 1 that fits into the plumbing tightly and the other that when the union is tightened compresses to give a compression seal that will last for years.
Note: Seals corrode quicker when the PH isn't maintained properly or high levels of chlorine or bromine.
When fitting a heater tube seal to your spa heater, make sure it has a little lubricant on its faces so it seats tightly (Vaseline is perfect for this). Never over tighten unions after fitting a new seal on your hot tub heater as this can lead to damage down the line.
We recommend to replace the seals on hot tubs and spas once a year.
