Sealant application

When applying the sealant on the metal gas pipes, does it really matter if the sealant travels to inside the pipes i.e. beyond the threads. Would it not harden up and cause the semi blockage of the gas down the road.

Also it is a metal sealant which says it is combustible. Does it need be used at all being combustible. I am not sure allowing this to be used, although on the bottle it says it lubricates and seals all the gas connections etc.

What type/brand sealant are you using. No you don't want to put on too much and allow any to get into the inside of the gas line. Orifices are not forgiving.

The end two threads should be left bare. Make sure the sealant is listed for the type of gas (natural or LP) you are using. A non-hardening, soft-set pipe sealant is preferred for gas piping. The most commonly used one around here is RectorSeal #5.

For your own safety, call a gas fitter.
