Permatex Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker is a fast-curing, sensor safe, low odor, non-corrosive formula that retains high flexibility, and oil resistance properties through use of a patented adhesion system. This gasket maker meets performance specs of OE silicone gaskets and is OEM specified. For dealership warranty requirements it also ensures extended drivetrain warranty compliance. Temperature range -65 degrees fahrenheit to 500 degrees fahrenheit intermittent; resists auto and shop fluids and vibration. These gasket makers offer significant performance advantages, excellent torque retention and hi-temp, sensor-safe properties. Extended warranties, engine sensors and new component materials such as aluminum, bi-metal alloys and high-tech plastics, have created the need for superior RTV silicone gasket makers in both OEM production and service applications. Permatex always has the right gasket maker for your application.
I've used different silicone gasket makers before, but Permatex Ultra Black is definitely among the best. The 5 oz tubes are just right for my needs, and the oil resistance is top-notch. I keep a pack handy for any future repairs.

Perfect for DIY enthusiasts
As someone who loves working on various DIY projects, this RTV silicone gasket maker is a lifesaver! The oil resistance is phenomenal, and the six-pack is super convenient. I've used it for my motorcycle and other appliances around the house with great results.

Not what I expected
I was a bit disappointed with the Permatex Ultra Black. It looks great in the tube, but it didn't cure as quickly as I thought it would. Had to wait longer for it to set before I could put everything back together. Hopefully, it holds up!

Great for my car repairs
I used the Permatex Ultra Black RTV for sealing a leaking oil pan, and it worked like a charm! The oil resistance is legit, and I love that it comes in a pack of six tubes. It's enough for multiple projects, which is great since I tend to work on my cars often.

Decent product but tricky to apply
This Permatex gasket maker does a good job at resisting oil, but I found the application a bit messy. The silicone is thick, so getting an even bead took a few tries. I did get it to seal well eventually, so it does its job!
