Joint compound on brass fittings for natural gas?

larrycassidy · 07-13-2009, 02:05 AM

Hi,
I recently had my bbq converted to natural gas. The gas is coming in on a black iron pipe with a shutoff valve and a 1/2 inch flare. I need to split the line using a T-connector (to run gas to main grill and a separate side burner). Should I use joint compound on my connections?

Thanks in advance!

Use pipe dope for non-flared fitting. Flared fittings need nothing.

I'd use pipe dope on all black pipe connections. Make sure you use the one that is specifically for gas.

Flare fittings are machined and need no joint compound on them.

This is correct... It just gives me that warm fuzzy feeling to use it on flared fittings

Gives me the warm fuzzies too. Just remember that on compression and flared fittings the threads are NOT what causes the gas/water tight seal. On compression it is the ferrule and on the flared fitting it is the mating surfaces themselves. The use of the pipe dope on ferrules and mating surfaces doesnt hurt and well I love those warm fuzzies.
