It works fine, but gunks up the threads (when the paste dries). If you want to re-use the fittings a few months down the road, you will need to take time to clean them with a little metal pick or tiny screwdriver. Bottom line is that it does a great job of sealing. **Q: can you loosen the joint once it has been applied?** A: Non-hardening gray paste seals and lubricates threaded joints It's not a cement. **Q: can this be used used to seal the drain plug in the bilge of my fishing boat? Can the plug be removed after the fishing season?** A: It may be worth a try. This pipe fitting is not suppose to harden so I would think you'd be ok in removing the plug at the end of fishing season. **Q: I put a splitter for the water hose and washing machine with plumbers tape and still leaks. Will this stop the leak?** A: Most hose bibs, hose splitters, washing machine hose, and garden hoses use rubber gaskets to seal all connections. I would replace and/or make sure those are installed. I will say however that in my experience, this paste performs better than tape on imperfect connections. ## Frequently Bought Together - Oatey 31231 Pipe Joint Compound, 8 oz, White - Simmons 1695 Malleable Point Well Drive Cap, 1-1/4 in - 5PCS For MFG DRCOUP 125 1-1/4" Female Well Point Drive Coupling --- ## 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.ec/products/21346200-31231-pipe-joint-compound-with-ptfe-with-brush-8-fl](https://www.desertcart.ec/products/21346200-31231-pipe-joint-compound-with-ptfe-with-brush-8-fl) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-22*
