For anyone who needs a good pipe dope
From SG. Does its job really well. Use it with teflon tape and I guarantee there’s no way it will leak even if u pressurised it immediately

Reliable Sealant That Gets the Job Done!
The RectorSeal No. 5 Pipe Thread Sealant is hands down one of the best sealants I’ve used. It applies smoothly, spreads evenly, and seals perfectly every time. I’ve used it on both metal and PVC threads with zero leaks — even under pressure. It stays pliable without hardening or cracking, which makes maintenance easy. The 4-ounce can is the perfect size for both professionals and DIY jobs, and a little goes a long way. Cleanup is simple, and the consistency is just right — not too thick, not too runny. If you’re looking for a dependable thread sealant that works across plumbing, gas, and industrial applications, this is the one. RectorSeal never disappoints! 💪🧰

Great product
Do not waste your time with gas tape. This does the job. Overpriced by about $15. Local hardware stores carry for much less.
