Can I connect a brass pipe to a steel pipe on a gas line?

Hi Macoyo:

Here's the code in my area...

Threaded brass or copper pipe shall not be used with gasses corrosive to such material.

Corrosive is defined as a gas with an average hydrogen sulfide content of 0.03 grains per 100 SCF. Here, copper/brass can usually be used with propane gas, but not usually natural gas.

All that being said, I think this is a question that needs to be answered by a local plumbing/gas inspector... ;)

Let me know what they tell you, OK? I am always curious to hear what each town/city/state has to say in these things!

Thanks...

Mark
