Review: Used it to replace tri-port gasket on pool filter. Perfect! - My pool filter has a triport gasket that began leaking after 10 years of use. I got a replacement gasket, opened up the valve, removed the old one, cleaned up the surface and put the new one in on a bed of Blue RTV. I let it get sticky for about 10 minutes which was on the instructions before putting the new gasket in place. What I didnt realize is that there is a right-side-up for that rubber gasket, and of course with Murphy's law, I had a 50/50 chance of getting it right -- which I did not! I had to disassemble the valve, remove the new/old gasket which had cured by this time. It came out perfectly and easily! A new bed of RTV went in, 10 minutes later the new/new gasket, and then 24 hours of cure time. Not a single leak and operates like new. Some people use superglue to hold in the gasket which would have been a disaster since you will have to replace it after either years or the realization you got it in upside down. The RTV came out like a dream and left no residue.
Review: You need it. - Keep some around at all times. Great for small engines and high heat area.
