OEM specified. Specially formulated to withstand the harsh gear oil environment found in differentials and transfer cases. Because gear oil has friction modifiers that break down normal RTV and cause leaking, this silicone has been tested to OEM specifications to ensure complete sealing. As a gasket maker, it seeks and seals leak paths that cut gaskets cannot.

      Comments about Permatex Gear Oil RTV Sealant (3 oz):

      Put it on gasket then put gasket on differential cover (Ford manual recommends using both) and the gasket literally wouldn't budge after 5 minutes. Let sit for an hour after thumb-tightening differential cover on to differential, then torqued to specs. Waited 24 hours, filled up... no leaks after test driving. Seems great so far, only more miles will tell if it holds up. Somewhat difficult to squeeze out of tube... I mean I really had to squeeze hard, but it's the only one specifically made for differential gear oil.

      Installed on 2001 RWD differential cover over 15 months ago and still no leaks. Apply Permatex gasket maker to both sides of gasket.

        Time has yet to tell, but this stuff is like ford or international grey silicone. It formed sucah a seal i had my diff cover misaligned just a hair and had to use a hammer to tap into place!! Only reason for a 4 star is I haven't had it more than a couple days...

        Was hard to get out of tube, but worth knowing it won't leak in a few months, as other rtv's have in past. worth the extra money.

            Works as designed. Some RTV sealants tend to leak even within short periods of time. I used this the same day I received it and it doesn't leak.

              Why don't the "advisors" answer the question asked instead of just copying and pasting the text from the specifications for this product? I hadn't noticed it before but see it happening everywhere on the QandA for a large number of products on this website now.
