This premium RTV gasket maker exceeds manufacturers' performance requirements, featuring maximum vibration resistance and outstanding resistance to oils, cooling and shop fluids. Non-corrosive and low-odor. OEM specified, with a temperature range of -65 degrees fahrenheit to 500 degrees fahrenheit, intermittent. Permatex always has the right gasket maker for your application. Review: Super sealant! - Great RTV sealant for 2006 Corolla. Used in timing chain area—the split between the timing block and the engine block—when replacing engine gasket to prevent oil leaks. Car runs better than new! Quantity is more than enough for several vehicles. Water and oil resistant. Let it dry and the adhesion will last a lifetime. Thick but liquid for flow. Review: Works great to clean up a mess - Used Ultra Gray gasket maker on a job that was “definitely not that bad” and somehow leaking from everywhere. Slapped this stuff on, bolted it together, and now it’s tighter than my budget after buying tools I didn’t need. It sticks, it seals, and it doesn’t care how confident you were before you realized the gasket was toast. Oil stays in. Coolant stays where it belongs. No drips, no excuses. If you enjoy products that quietly make you look like you know what you’re doing, Ultra Gray is the hero you didn’t know you needed. Five stars. ## Features - Designed specially for high-torque and high vibration applications - Maximum vibration resistance, with outstanding resistance to oils, cooling and shop fluids - Low odor and non-corrosive formula - Suggested Applications: Valve covers, oil pans, intake manifold end seals, timing covers, water pumps, thermostat housings ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000HBGI8K | | Best Sellers Rank | #789 in Automotive ( See Top 100 in Automotive ) #2 in Gasket Sealers | | Brand | Permatex | | Brand Name | Permatex | | Color | Ultra Gray | | Customer Reviews | 4.8 out of 5 stars 5,389 Reviews | | Global Trade Identification Number | 00686226821942 | | Included Components | Unit^Instruction Guide | | Item Shape | Round | | Item Thickness | 5 Inches | | Item Type Name | 599B U-GREY RTV | | Item Weight | 4.16 ounces | | Manufacturer | Permatex | | Material | Silicone | | Material Type | Silicone | | Model | 82194 | | Part Number | 82194 | | Pressure | 5 Inches of Mercury | | Shape | Round | | UPC | 686226821942 686226001139 | | Unit Count | 99 Grams | | Upper Temperature Rating | 500 Degrees Fahrenheit | | Warranty Description | LIMITED WARRANTY | ## Product Details - **Brand:** Permatex - **Color:** Ultra Gray - **Item Thickness:** 5 Inches - **Material:** Silicone - **Upper Temperature Rating:** 500 Degrees Fahrenheit ## Images ![82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, 3.0 oz. - Image 1](https://m.media-amazon.com/images/I/811ISBbKpxL.jpg) ![82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, 3.0 oz. - Image 2](https://m.media-amazon.com/images/I/81KIFlXwFdL.jpg) ![82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, 3.0 oz. - Image 3](https://m.media-amazon.com/images/I/81i-psqQnHL.jpg) ![82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, 3.0 oz. - Image 4](https://m.media-amazon.com/images/I/81SMFyiPRBL.jpg) ![82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, 3.0 oz. - Image 5](https://m.media-amazon.com/images/I/71XPCTZTLBL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Hello. Does this sealer is suitable for my scooter oil krancase gasket( to sealed it) ?** A: The Ultra Gray is the BMW Motorrad replacement gasket material for case applications. If it's recommended for BMW motorcycles it's probably great for a scooter. **Q: Can ultimate grey be used to hang a rear view mirror to the windshield. Mine falls off every few months.** A: I used high temp double sided epoxy tape. Wash the windshield and the mating surface on the mirror with detergent and rinse. Do not get any finger oil where you will be adhering. using 600 grit sandpaper, lightly abrade an area of the windshield that will be hidden by the mirror trim. Do the same for the mating surface. Apply the tape (or this adhesive) per manufacturer's instructions. Do it late in the day or in a garage so it's not in a baking car. Give it a chance to cure. If possible, bend a coathanger or something to give the mirror support while it's curing. **Q: can this be used on water pump Bolt threads?** A: You bet. Just follow the instructions on the tube precisely. **Q: Will it help on a valve cover gaskets?** A: Yes, just make sure you have a uniform thickness on the contact surface. I will usually only put it on the valve cover and not on the head. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super sealant! *by M***T on May 2, 2026* Great RTV sealant for 2006 Corolla.

Long-lasting if you cap the tube after use. *by D***G on March 2, 2025* If you're using this for a one-time application, you may want to opt for a smaller tube. However, if you use RTV a lot, this tube will last you a long time and the price is on-point. I saved quite a bit overall by just buying the bigger tube instead of smaller individual tubes. This is like that Granny's hot sauce- I use this s*** on everything! Very good stuff, you can cap the tube for reuse. Good high-temp RTV that resists oil and stuff. I've used it on applications like metal-to-plastic and the adhesion is great. The ease of use and thickness is also better than the smaller tubes in my opinion, because you can control the flow using any caulk gun of your choice. I recommend using a "finger" from nitrile gloves to cap the tube along with a wood screw or bolt. The only downside is it takes a while to cure compared to other similar RTVs (like "Great Stuff", etc). I used this to seal around a throttle body that had a snapped corner bolt on a bmw m50 motor, this was plastic-on-metal, and this RTV has held up for literally over 5 years so far with no signs of cracking or anything else. That's after hundreds or possibly thousands of heat cycles and exposure to CCV oils, etc. So yeah, It's very good. ## Frequently Bought Together - Permatex 82194 Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker, Sensor Safe And Non-Corrosive, For High Torque And Vibration Resistant Applications, 3 oz - Permatex 85080 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker, Sensor Safe And Non-Corrosive, For High Flex And Oil Resistant Applications 9.5 oz - Permatex 81630 Ultra Red High Temperature Gasket Maker, 3 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/3665369-82194-ultra-grey-rigid-high-torque-rtv-silicone-gasket-maker](https://www.desertcart.com.br/products/3665369-82194-ultra-grey-rigid-high-torque-rtv-silicone-gasket-maker) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-21*
