It works especially well on sealing thread that are not tapered pipe threads. I use this on my harley fluid drain plugs **Q: Does this product solidify after 72 hrs as cited in the tds? after being applied for 52 hrs it remains a soft tacky paste.** A: Hello. I use this product quite often. It holds very well, seals very well. I just put some on my differential fill plug and seals it great. To answer your question, this product, when first put on threaded hardware will be wet and soft and be able to seal low pressure and intermediate pressure. Parts can be readjusted, torqued, etcetera with in 24 hours of application. 72 hours just means it is fully cured and can withstand higher pressures. But, once applied, it holds very well within hours. Definitely within 24 hours. It does not solidify, it stays wet and soft. It's good stuff. Hope this helped. BJ **Q: I was told i could use this on an oil pressure sending unit and seen on websites it could be used. so someone just told me I shouldn't. So can i?** A: Yes, it works great. I use it on oil and brake system components exposed to high pressures and temperatures. No leaks, ever. Make sure it is applied to clean Dry threads. Use a solvent to clean threads, let dry, then apply the permatex. Be careful not to cross thread. Don't overtighten!! Cheers **Q: Will this work on differential bolts that thread through into the case and are exposed to differential fluid?** A: Hello Michal. Yes this thread sealant does work on sealing differential fluid. I have used and know for sure it works on sealing the differential fill plug. If your referring to the cover bolts, you need a gasket or gasket maker to seal the cover. I'm not sure what bolts your referring to, but yes this sealant will seal differential fluid. Hope this helped. ## Customer Reviews ### ⭐⭐⭐⭐⭐ If you need it, you need it! *by I***N on April 14, 2026* Permatex always makes solid products, and this high-temperature thread sealant is no exception.

Somewhat slow drying so that you can make adjustments, it can be a little messy but wipes up easily and it viscosity is not to thick. ## Frequently Bought Together - Permatex 59214 High Temperature Thread Sealant, 6 ml Tube, Pack of 1 - 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 81182 Gear Oil RTV Gasket Maker, 3 oz (Packaging May Vary) --- ## 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.pt/products/3775982-59214-high-temperature-thread-sealant-6-ml-tube](https://www.desertcart.pt/products/3775982-59214-high-temperature-thread-sealant-6-ml-tube) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-27*
