(1 Pair Gecko Heater / Pump Seals)
Fit any 2" plumbing tail pieces on either heaters or pumps
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.

Hot Tub Heater Guides
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
