Reliable high-torque RTV silicone — my husband’s go-to gasket maker
My husband picked up this Permatex 82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker for some repair projects. It does exactly what it’s supposed to — forms a strong, durable seal.What works well:• Stays flexible enough to handle vibration and temperature changes but cures rigid.• Good for making custom gaskets on oil pans, valve covers, water pumps, and similar automotive/equipment parts.• Easy to apply from the tube and cleans up nicely before it sets.• Trusted Permatex quality at a fair price for the 3 oz tube.He’s used Permatex products for years and this one performed as expected. Solid choice if you need a high-performance silicone gasket maker for mechanical repairs.

Metal tube that actually seals
Mostly grabbed this for my old Honda valve cover, because shop quotes were silly. I’m a freelance designer but i wrench on weekends. Tube opens clean, spreads smooth, and cures firm without feeling brittle. Did a hard freeway pull after 24 hours and the gasket line stayed bone dry, which made me really glad I did it myself adn saved the cash.

Fast to cure with no odor and lasts indefinitely.
I was a bit surprised to receive such a heavily damaged item, but since the product in the tube wasn’t damaged, I didn’t worry too much about it. This product is quick curing and has a very low odor. It’s easy to apply and creates a long-lasting, waterproof seal. The price is very reasonable for such a quality product.

No leaks, no issues—just did its job.Sets up nicely and feels solid once cured. Definitely gave me confidence in the repair.Overall, great stuff and I’d use it again without hesitation.

Cant go wrong with Permatex gray RTV gasket maker
Permatex ultra great is the best RTV gasket maker i have used, can be mess to work with unless you have lots of room to work. The adhesion is very good along with the appearance. made for all type of material, great fit

Super sealant!
Great RTV sealant for 2006 Corolla. Used in timing chain area—the split between the timing block and the engine block—when replacing engine gasket to prevent oil leaks. Car runs better than new! Quantity is more than enough for several vehicles. Water and oil resistant. Let it dry and the adhesion will last a lifetime. Thick but liquid for flow.

used it for a car water pump change.
used it for a car water pump change it does the job like other RTVs I tried , other reason because it says " it's save for sensors ".

Recommended
Used on a Toyota Yaris as similar to Toyota oem. Worked very well on timing chain cover and sump. It’s at a good price point, created a great seal when used to recommended bead size torque on a challenging sump pan ( the one with 2 bolts inside bell housing)
