Thanks all.

I think everyone is fine if someone does not want to use a sealant on their lines, copper flares should seal almost all of the time if done right, good luck.

The Nylog is not a thread sealant, though works great as a thread sealant, rather it is designed to seal more than that.
It looks and feels like snot, and it does not dry ever, and does not blow out. This is not a glue, but more of a gasket that remains tacky and liquid, but will restrain very high pressures.
Adding Nylog to a connection that does not require a sealant is harmless, and will ensure you have the best and most long lasting seal possible.

I have been able to re-use crush washers because of Nylog with no leaks.

On my current new copper piping the Nylog even held pressure with just a hand tightening of the flare nuts, something that could never ever happen without it.

I highly recommend using this product on your pipe fittings.

There are two types, Red and Blue. I use the Red for this application.

It is also "food safe" and used in the refrigeration industry on large units.

I do not work for or represent the brand, but just sharing good info.
I got mine on Ebay for about $9. thanks

I have a an OLD Marshall reg that comes apart and I've made new viton internal parts to keep it working but a couple of weeks ago, I thought it was finished. I smelled mercaptan and I soaped it repeatedly and I couldn't see bubbles but when I rinsed it off and watched a little longer, I finally saw a TINY bubble in the water, on the bonnet of the low tank gauge. The bubble was too tiny to show through the soap. Water actually worked better than soap, that time. I checked the gauge diaphragm and all I had to do was tighten the bonnet nut a little tighter. Maybe I'll get another 20 years out of it. Craig

There is no such thing as a completely sealed LP system. The system will leak down the LP in the system when the Tank is turned off over days/weeks.
YOU NEVER USE OR NEED TO USE ANY SEALANT ON A FLARE FITTING. NEVER!
If a flare leaks FIX the copper flare, do not attempt to use sealant. PIPE fittings, you use sealant/teflon tape. Doug
Thank you for this information. I have always wondered about the leakdown after storage.
I agree no sealant to be used on a flare.

I put a new hose from the tank to the regulator. Soaped it up and no bubbles on the hose crimp, or the connection at the reg. No bubbles anywhere.
Everything is new except the furnace.
The Nylog means the flare fittings are not leaking too.
The only thing unknown is the furnace solenoid gas valve. No propane smell though.

So, the pressure dial still goes down in pressure within hours. Is this normal, again??
