RTV Silicone Sealant and Gasket Maker: Up to 500 Degree F Heat, High Temp Silicone Sealant, 3 oz/85g Tube - Black

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.

Keep some around at all times. Great for small engines and high heat area.

Worked great as expected and easy to use

Take this review with a grain of salt. I’m a little bit of an idiot with repairs. I am unclear what RTV silicone gasket maker is still apparently vs ge silicone. I thought I needed this for a hot tub light gasket. Turned out I made it way more complicated than needed but I did use a little on it. I played with it quite a bit. It really seems like silicone caulk to me. However this is water resistant and high temp, which high temp I thought I needed. Ge silicone is waterproof. I guess depends on what you need. Both seem to home well and be flexible. I did use it to help seal an annoyingly loose seal gasket for a portable water pump. Doesn’t look so good but does stay in place now. It was spraying out from the sides previously at a certain level. It is easier to use than caulk gun I think. Easier without the small pointed tub piece, but that makes it more exact. Still a hard to get perfect Wear gloves. I also recommend having a paper clip andor tooth pick ready so you can clean out and also perfect some fine points. The tub will get full and hard to reuse without cleaning out.

Good product, just applied, let it set for a few and it has held up no issues

Worked great to repair a dishwasher gasket. Highly recommend.

Used this to reseal a water pump. It’s a little different than what I’ve been using before. You apply it and let it sit for about 10 minutes and then assemble the parts. Torque lightly and let it cure. I left it alone for 24 hours and didn’t retorque. It’s leak free. I probably could have used it sooner, but I had time, so I let it cure completely and now the water pump is leaking free. It was actually easy to spread. I applied liberally and flattened it out using a spatula. I let it sit and assembled.

Cannot add value on product as it was retuned. Did not realize this wasn’t a sealer but a gasket creator.
