Actually, Rectorseal would probably be one of the BEST products to use in this situation. The product description states that it can be used on PVC and CPVC. Rectorseal is a tan-colored, thick paste that acts as a lubricant and sealant on threaded connections. It is NON-hardening, so it STAYS as a paste. Since the PVC clean-out is a threaded connection, it should work just fine, without hardening or deforming your PVC pipe. **Q: The picture and the description both say 4 oz (1/4 pint). the technical details say 8 ounces. which is it?** A: It is 4 oz as described on the bottle.I do apologize for any confusion.Thank you! **Q: Can we use for natural gas black pipe fitting or its only for brass fitting like valve etc. thanks** A: Use it on black iron or galgalvanized. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Never A Leak *by C***S on 7 April 2025* ### ⭐⭐⭐⭐⭐ good for keeping fittings easy to change *by A***R on 15 May 2019* ### ⭐⭐⭐⭐⭐ For anyone who needs a good pipe dope *by F***G on 13 July 2024* ## Frequently Bought Together - Rectorseal 25631 4-Ounce No. 5 Pipe Thread Sealant , Yellow , 4 fl. oz. - VOTMELL 4 Rolls 1/2 Inch(W) X 520 Inches(L) Teflon Plumbers Tape,Pipe Sealing & Plumbing Thread Tape,PTFE Water Sealant Seal for Shower Head,White - Harvey 017065 Gas Line PTFE Thread Seal Tape --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/416884044-rectorseal-25631-4-ounce-no-5-pipe-thread-sealant](https://www.desertcart.co.th/products/416884044-rectorseal-25631-4-ounce-no-5-pipe-thread-sealant) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
