Permatex 81160 High-Temp Red RTV Silicone Gasket, 3 oz

Flawless victory. No really, used the product to make a needed RTV seal for a furnace blower install and did the job perfectly. This one sets immediately so be quick on the install.

Works well. Can withstand 15 psi for 20 minutes under heat for many uses. I never had to repair it after many uses. Dries well. It can be a little messy but I use gloves. For what I need to seal you do not need a lot to get job done.

I'd like to start by saying that I use this specifically to fill the grooves for response systems in YoYo's, but it's fantastic for this. It's a little thicker than the clear flowable silicone, but that makes it a little easier to work with as well admittedly. You just have to make sure that you use an old card or something when you are done to smooth out the top layer, then let it set and you are good to go. Good response and grip to the string, and lasts much longer than the flowable, with minimal extra effort. All in all, works great, would recommend!

Product does what it is supposed to. My only complaint, is that the lid broke... This is probably my own fault being that I was messy and replaced the plastic white lid to the bottle without wiping down the treads. Because the treads were covered with the silicone and I screwed the lid on while it was covered, the lid melded to the metal. The next time I went to take the plastic lid off it cracked because it has sealed so tightly to the bottle.... I guess it did what it was supposed to do, but I was bummed because I was now lid-less. I had to toss the cap. I did find somewhat of an easy solution though to being lidless... I just squeeze out an extra blob and use it as a makeshift lid. When it dried it sealed the the exit hole nicely without ruining the rest of what is in the bottle. I then just reuse the blob each time, resealing it to the bottle... My advice to you though, save yourself the trouble and wipe down the metal treads before screwing the plastic cap back on. :-)

Works really good put it directly where the exhaust manifold mounts to the engine sealed up the gap checked it right after it had been running it’s really high temperature good stuff

Worked very well for sealing up connections on our interior pipes for our pellet stove

First thing to be aware of: this silicone is a bit thicker than colorless RTV silicone. I'd describe its consistency as being more paste-like than gel-like. It's also nearly odorless compared to general-purpose colorless RTV silicones.It does hold up well at high temperatures. I've used and abused this stuff at temperatures that I know were in excess of its rated continuous-duty temperature, and it held up regardless.Although my application was not automotive, this product would definitely be suitable for automotive applications downstream of the exhaust headers. If you have an installed turbo, it could be used downstream of the turbo...perhaps even at the turbo outlet.

I bought this specifically to bleed the abs unit on my 2005 Chevrolet Silverado of which the 99-05 model years are generally considered the same (or GMC Sierra). My brake lines rusted through from the master cylinder to the abs unit. Upon repairing the lines I bled the brakes til' my face turned blue to no avail. After googling and finding the abs unit needs to be bled I went directly to smile.amazon.com to find an affordable tool that would do the job and save money and time from taking it to a shop. The menus were ok to go through and I almost didn't think this had abs bleed for a moment but then fiddled a second and got to the special function. I am happy to report that this works as indicated for this particular function. As I have not attempted any other vehicle I cannot report either way on another make and model. I did not try any other functions at this time but will add to this review as I use the tool more. A shop would easily charge what this cost just to bleed the abs/brakes alone without the repair. And unless you wanted to risk driving on faulty brakes the tow would cost what this tool cost as well. I recommend giving it a go!
