It says 3/4 of a thread but I don’t know how much that really is...** A: Loctite 592 has a ribbon style nozzle, wide slot for discharge. The correct method is to hold the end of the nozzle up against the side of the fitting, so the width of the slot opening is across a few threads. As you squeeze the tube gently and dispense the sealant into the root of the threads, slide the nozzle around the fitting in order to go ¾ of the way around the tube. Feel free to go 360° around if you wish. That’s a little excess material but won’t really hurt. You end up with sealant in the root of the treads only, which is enough. Hope that helps. **Q: Is the "activator" necessary or will the sealant work without it?** A: While the manufacturer recommends cleaning with their cleaner (that just happens to be a primer and activator) I have used the 592 thread sealant and even the 518 gasket maker with other cleaners such as vm&p naphtha (that is not a primer or activator) with excellent results. A primer is recommended when both surfaces are considered "inactive". The Loctite primer defines what this is. **Q: How strong is the thread locker? Can fittings be removed?** A: This is not thread locker. This is thread sealant (like pipe dope). You will be able to remove the fittings. **Q: I have a brass engine coolant temperature gauge leaking. Do i have to drain the coolant before using and let dry completely?** A: The fitting must be clean and dry prior to applying the 592, and it should be allowed to cure for at least 24 hours (preferably 72) before adding the coolant back into the system.

Highly recommended. Goes on easily around the threads. It can be a tight fit if applied to the start of a thread application so it's recommended to have this applied towards the end. I used this for the installation of a Jagg Oil Cooler and it worked as it should. The instructions of the Jag Oil Cooler include the use of this thread sealant. No leaks and no complaints. I also recently applied to the end of the oil drain plug after an oil change to ensure there would be no leaks and it worked great. Of course the oil drain plug o-ring was still there so this was applied to the threads just before the o-ring. The o-ring has a tad bit of new oil put on it. ### ⭐⭐⭐⭐⭐ Hard to get in local stores *by on Reviewed in Canada 3 August 2023* Used it for threaded flange fittings. Two day shipping is rhe best. ### ⭐⭐⭐⭐⭐ The right stuff for the job *by on Reviewed in Canada 15 April 2021* Exactly what I wanted for my high performance built engine. One whole race season and the results are lasting. ## Frequently Bought Together - LOCTITE PST 592 Thread Sealant for Automotive: Low-Pressure, High-Viscosity, Anaerobic, Prevents Galling | Opaque, Off-White, 50 ml Tube (PN: 483630) - Slippery Pete 5cc Hand Pump Transfers Gear Oil, Transmission and Differential Fluids From Quart Bottles (Not for Red Line Quarts) (1) - Chrysler (68218057AC) Genuine Mopar Fluid ATF+4 Automatic Transmission Fluid - 1 Quart, 32 Ounces --- ## 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.sk/products/302072217-37397-592-thread-sealant-50-mililiter-tube](https://www.desertcart.sk/products/302072217-37397-592-thread-sealant-50-mililiter-tube) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-06*
