I know if you put it on a airhose fitting and then pressurize it right away, it won't hold and start to push it out of the threads. I think it takes 24hrs to setup fully. **Q: Use on drinking water systems?** A: Not sure, I used it on air lines outside. I would use Teflon tape on water. **Q: Can one use teflon tape, then apply this product on top of the tape (for water pipe threads)?** A: You would use one or the other, you wouldn't use both... this would take the place of teflon tape. **Q: Can this be used on a high pressured air mattress hose? I need something to seal the threads, but not close off the intake/outtake capacity of hose.** A: Yes, you should be able to use it on air mattress hose, as long as they're threaded and not just push-on type connections ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality. *by V***O on 14 April 2025* Good quality. ### ⭐⭐⭐⭐⭐ Product satisfaction *by D***N on 28 August 2025* Very good product ### ⭐⭐⭐⭐⭐ Permatex white thread sealant *by P***E on 6 April 2024* Make sure that you read instructions for useage. this item is not applicable to all type of thread sealing applications. ## Frequently Bought Together - Permatex 80631 Thread Sealant with PTFE, 1 oz. , White - RUXIFEY Single Side 3rd Third Brake Light Seal Gasket Compatible with Silverado GMC 1500 2500HD 3500HD 2014 to 2018 High Mount Stop Lamp Assembly, 2nd Gen - Permatex 80050 Clear RTV Silicone Adhesive Sealant, 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.hk/products/255417978-permatex-80631-thread-sealant-with-ptfe-1-oz-white](https://www.desertcart.hk/products/255417978-permatex-80631-thread-sealant-with-ptfe-1-oz-white) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-16*
