Permatex82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, Sensor Safe And Non-Corrosive, For High Torque And Vibration Resistant Applications, 3 oz

Worked great on the threads of a PCV valve to seal it well.

great product.

If you're using this for a one-time application, you may want to opt for a smaller tube. However, if you use RTV a lot, this tube will last you a long time and the price is on-point. I saved quite a bit overall by just buying the bigger tube instead of smaller individual tubes. This is like that Granny's hot sauce- I use this s*** on everything!Very good stuff, you can cap the tube for reuse. Good high-temp RTV that resists oil and stuff. I've used it on applications like metal-to-plastic and the adhesion is great. The ease of use and thickness is also better than the smaller tubes in my opinion, because you can control the flow using any caulk gun of your choice.I recommend using a "finger" from nitrile gloves to cap the tube along with a wood screw or bolt.The only downside is it takes a while to cure compared to other similar RTVs (like "Great Stuff", etc).I used this to seal around a throttle body that had a snapped corner bolt on a bmw m50 motor, this was plastic-on-metal, and this RTV has held up for literally over 5 years so far with no signs of cracking or anything else. That's after hundreds or possibly thousands of heat cycles and exposure to CCV oils, etc.So yeah, It's very good.

Leak resistance quality

It is easy to use, it works, it is suitable for amateur and professional use, it achieves its purpose, just make sure the area you use it on is clean, there should be no oil or dirt, apply it only to two very clean metals, if the surface is oily and dirty, it will definitely not work, this information is for amateurs, professional friends already know, good luck

Used for my thermostat housing gasket to keep in place during install. Will also use on my timing cover for same purpose. The gasket doesn't always seal porous metal surfaces so a good idea to apply a light skin of this to seal up any irregularities.Let it skin over a bit and will seal/stick very well. Permatex quality cannot be beat. Just make sure you use the right "color" for the correct application!

Excelent product.
