## Overview

Permatex 81182 Gear Oil RTV Gasket Maker is a high-performance silicone paste engineered specifically for differentials and transfer cases. It withstands harsh gear oil environments and friction modifiers that degrade standard RTVs, ensuring a durable, OEM-tested seal. With fast curing and sensor-safe, non-toxic properties, it’s the trusted solution for professional-grade leak prevention in automotive maintenance.

## Description

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.

Review: 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.
Review: Product works perfect in this intended application. - I've been using this exact product in all of my front and rear differentials. The manufacturer says this product is specifically made for differentials and in dealing with the differential oil characteristics. I've never had a leak or any issue with this product. I believe in the manufacturer's hype. My friend uses the Permatex "Red" gasket maker with great success but given enough time and or mileage the "Red" gasket maker will leak in a differential application whereas the "Green" gasket maker does not leak. I recommend this product for this application.

A: It is good for any kind of oil, diff, transmission or engine.

**Q: Can I use it for mustang gt?**
A: Yes, it is rated for Mustang GT

**Q: I have a small drip on a differential stud.. on a Tacoma will this be good to use as a dressing over the hex washer nut to stop the drip??**
A: First off i would remove the nut then spray that area with brake cleaner. Then let dry then apply the sealer around the stud then use a flat washer followed by a lockwasher then the nut and tighten. Give the sealant a chance to cure. Good to Go.

Used this sealant on the rear diff cover on my '21 F-250. It sealed just fine but I would rather have a gasket.
