Permatex 81182 Gear Oil RTV Gasket Maker is a 3 oz specialty silicone sealant engineered to withstand harsh gear oil environments in differentials and transfer cases. Tested to OEM standards, it resists friction modifiers that degrade normal RTVs, sealing leak paths beyond traditional gaskets. Sensor-safe, non-toxic, and non-flammable, it’s the trusted choice for professional-grade vehicle maintenance.

Snelle levering
Snelle levering, product doet wat het behoort te doen. Gebruikt voor de dichting van een differentieel huis van een BMW E46 sedan bij het vervangen van de rear diff bushing.

Works Great, Follow Instructions
When you work on your differential, you must decide three things: gasket or no gasket, RTV or no RTV and which RTV is best? My preference is to first stick the gasket to the cover with a small bead of this RTV. Then, apply a small bead of this RTV to the differential housing. This way prevents an accidental transfer of RTV from the cover to the ring gear if the cover touches the gear. Using only the socket and your hand, tighten the bolts in a crisscrossing star pattern until they are as tight as you can get them. The RTV package says let it cure for 1 hour, so let it cure for 1 hour. Then, using a torque wrench, slowly increase the bolt torques using the star pattern until all bolts are properly torqued. Let it cure for 23 hours before introducing the gear oil. Following this approach, I have never had a leak. Nice product. Does what it says, but you must follow the instructions.
