Great alternative to Balboa Heater Seals (These will last longer)

Seals for hot tub heaters: Gecko amongst many other brands and makes.

These seals flat on one side and have a ridge on the other, 1 side 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.

Fitting instructions:

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.

stopped the leak
Thursday, 18 May 2017  | 

My Bilbao heater was leaking from the end union. The original washer was a white rubber washer . This component was a clear silicone type material but it did the job and fitted well. I put some clear silicone on the flat face to aid the seal as I had an open tube handy but it would probably have sealed without as it was nice and flexible. On thing I cannot understand is that the washer that came out had a semi circular contour on one side only but the illustration on the website for the Bilbao part had a semi circular contour on both sides. This was why I ordered the Gecko seals rather than the Bilbao seals as they appeared to be a closer match to the washer I was replacing in respect of shape
