About this item:
Permatex Gear Oil RTV Gasket Maker is specially formulated to withstand the harsh gear oil environment found in differentials and transfer cases. Gear oil has friction modifiers that break down normal RTV and cause leaking, but this specialty silicone has been tested to Original Equipment Manufacturer (OEM) specifications to ensure complete sealing power. As a gasket maker it seeks and seals leak paths that cut gaskets cannot. Suggested Applications: Differentials and transfer cases.

5.0 out of 5 stars Works great
Goes on easy and makes a good seal.
5.0 out of 5 stars Used this to seal up a rear differential on a 2019 F150 after changing the gear oil.
The media could not be loaded. Changed the rear differential gear oil on my 2019 F150 by removing the rear differential cover. Used this after cleaning the mating surfaces to seal up the cover and it's been leak free since refilling and driving about 800 miles. A few things to note 1) before opening the rear differential, be sure to first open the fill port. It wouldn't be very fun to remove the rear cover and then discover the fill port is frozen solid. 2) This gasket maker recommends 24 hours to set up before filling with oil. After about 4 hours, the squeeze out was pretty solid, but this series of services performed, and doing this at home made planning for the 24 hours possible. It would be my recommendation to wait, at least over night for this to cure fully. works as described, definitely recommend.
5.0 out of 5 stars Great to use when doing a transfer case
Absolutely love this product, used the ultra grey while doing a sye install and when fluid was added it leaked a lot. When I used their gear oil sealant it worked flawless.
5.0 out of 5 stars So Far, So Good
Used this for the diff covers on my 4WD F250. Easy to work with and has created a leak proof seal so far. Just follow the directions. This was enough to do the front and rear diff covers, with a little bit left over.
4.0 out of 5 stars So far so good
Seems to work well. No leaks so far.The only negative is that the RTV is very thick and takes quite a bit of pressure to get out of the tube.

5.0 out of 5 stars Great seal. No leaks. Follow directions exactly.
Used on my F350 sterling rear end. Worked perfectly
5.0 out of 5 stars No leaks, good quality sealant.
Used this product on a 2010 ford f150 diffrential. I've used this several times with no issues. One bit of advise, many videos out there on YT and many apply the sealant on the diffrential cover but when you're on your back trying to put it in place, one tend to touch the sealant smearing it. It is much easier to put the sealant on the differential housing first and then putting the cover. It avoids touching the bead of sealant.
Great product.
Fast shipping and worked like advertised. Did both front and rear differentials with some left in the tube's. No leaks
No leaks where I used this!
Used this to seal the differentials on my Land Rover - works perfectly, as I expected it to do. It's specifically designed to seal compartments containing gear oil. I used Blue Hylomar - a good sealant, but not specific to gear oil sealing - on some other gearbox components & I do have a few small leaks. Well, it's a Land Rover, they do leak - but I think this Permatex Gear Oil sealer is most likely to minimize them! Recommended!
Silicon magnifico
lo use para sellar la trasmisión de mi auto y funcionó perfectamente...
