Doing a job on a gas meter rack. For several reasons, taking everything apart and using all new piping is not an option. I have isolated two small leaks and used ordinary pipe dope to reseal and it helps some, but two tiny leaks still remains when pressure tested. Is there a non-BS product that really forms a tough tight bond that will likely do the trick?

The problem isn't the pipe dope 99.99999% of the time. If you are using a dried out crumbly sealant, that is most of the problem. If the dope is good, you aren't getting it tight.

good product ..... still swear by permatex pipe joint compound

its only downside is its 'messiness' and virtual impossibility to clean off one's hands

it is black - stinky - sticky - gooey - clingy - oozy - and penetrating .... all at the same time

it never COMPLETELY hardens but does FIRM UP soon after application making the best pipe thread sealant I have found in 40 years

I don't use it on everything because it is sooooooooo messy

Permatex, non-hardening type ---- Used on US Navy ships ---- good enough for me. (Yes it is messy.)

Therefore, it depends on who you ask

Thanks guys. Looks like Permatex gets the most votes but if someone feels there is something better, please chime in. Thanks.

I still think if you have a leak, redoped the pipes, and still have a leak, you don't need different dope. You need new pipe, or need to tighten it down properly. There isn't a situation where you need to try to slide a little something on the leak because "all new piping is not an option" You are messing with GAS! Leaks can be fatal in multiple ways.

KCRoto has some very important words which I will take the liberty to repeat " You are messing with GAS! Leaks can be fatal in multiple ways.".

I don't agree with the 99.9999% ... percentage however it do agree with the basic concept and will give it in the 90% plus range.

Whatever kind/brand of sealant you use be sure to read the label to make sure it is designed for gas (natural?) (propane?) recognizing that not all sealants are the same.

Ok, so perhaps a slight exaggeration to prove a point.

Thanks KCRoto for the free tummy/stomach exercises .... that was good My stomach is still moving up and down from laughing. Yup

90%, 95%, 99.9999% what the heck .... we got the idea and that was the most important thing and you were absolutely right on.

it's important to remember that it's the threads that make the joint.
make sure you have a quality threader with good dies and somebody who
knows what is right.

If you have leaks you may have bad threads.
