Should Sealant be Used on Propane Gas Line Fittings

Published 12/14/2016

Question:

I installed this device with no problems including testing it several times for leaks... no leaks. Many people keep telling me that I need to use the yellow PTFE tape on the threads to ensure I dont have any leaks. I know that I shouldnt use tape on the 1/4inch flared connection but what about the main two connections from the large female POL and Male ACME threads? Thanks for the advise.

Yes you should use some kind of sealant on threaded fittings whether it is the tape or pipe dope. We recently had a propane manufacturer visit us for training so I can say for sure that yes you should use a sealant on threaded fittings. No sealant though on the flare fittings just like you said.
