Tested to OEM standards, it resists friction modifiers that degrade typical RTVs, seals leak paths traditional gaskets miss, and cures quickly for efficient maintenance. Non-toxic and sensor-safe, it’s trusted by professionals for reliable, long-lasting sealing performance. ## 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: 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. Review: Succeeded where a traditional gasket failed. - I bought an aftermarket differential cover for my Silverado, and after trying two different OEM gaskets, it would still leak. I ended up buying this product to get a good seal, and it worked exactly as it should. No leaks, no slow dripping, just a total seal when the gasket couldn't get the job done. I also didn't need to wait the full 24 hours for the RTV to fully cure. I followed the instructions as listed, but I gave it 5 hours to cure. I think the 95 degree Texas heat probably helped speed up the curing process. Regardless, this is a great product and it does what it's supposed to do. ## Features - Specially formulated to withstand the harsh gear oil environment found in differentials and transfer cases - Specialty silicone does not break down against gear oil friction modifiers - Seeks and seals leak paths that cut gaskets cannot - Tested to Original Equipment Manufacturer (OEM) specifications to ensure complete sealing power - Sensor safe, non-toxic, and non-flammable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0023GM2KK | | Brand | Permatex | | Brand Name | Permatex | | Compatible Material | Gear Oil | | Container Type | Tube | | Customer Reviews | 4.8 out of 5 stars 2,108 Reviews | | Flash Point | 200 Degrees Fahrenheit | | Global Trade Identification Number | 00686226811820 | | Included Components | Item | | Item Form | Oil | | Item Type Name | 81182-CAN | | Item Weight | 109 g | | Liquid Volume | 3 Fluid Ounces | | Manufacturer | Permatex | | Material | Silicone | | Material Type | Silicone | | Model Number | 81182 | | Number of Items | 1 | | Package Information | Tube | | Part Number | 81182 | | Recommended Uses For Product | Fleet and plant maintenance. | | Specific Uses For Product | Fleet and plant maintenance. | | UPC | 686226811820 | | Unit Count | 3.0 Ounce | | Viscosity | Paste | ## Product Details - **Material:** Silicone - **Brand:** Permatex - **Package Information:** Tube - **Liquid Volume:** 3 Fluid Ounces - **Item Weight:** 0.24 Pounds ## Images ![Permatex 81182 Gear Oil RTV Gasket Maker, 3 oz. - Image 1](https://m.media-amazon.com/images/I/71CbZTL0iXL.jpg) ![Permatex 81182 Gear Oil RTV Gasket Maker, 3 oz. - Image 2](https://m.media-amazon.com/images/I/81JWRXyeLRL.jpg) ![Permatex 81182 Gear Oil RTV Gasket Maker, 3 oz. - Image 3](https://m.media-amazon.com/images/I/41tn8wUN5WL.jpg) ## Questions & Answers **Q: Is one tube enough or front and rear differentials of Permatex 81182 Gear Oil RTV Gasket Maker, 3 oz?** A: More than likely but it also depend upon the size of the differential housing(s) and how you apply it. If you apply a 1/8" or 3/16" wide bead, probably so! **Q: Can it be used in transmission pan too ? Or is just for diffs and transfer case ?** 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Snelle levering *by R***S on 3 January 2026* Snelle levering, product doet wat het behoort te doen.
