Contact the gas supplier and find out what makes them happy.

Is it Pex or is it polyethylene gas line?

Or is there a Pex approved for gas?

Poly gas line usually runs from the utility which also can be Poly to the house underground and then stubbed out outside the house to black iron (sched 40) and then possibly CSST (corrugated stainless/bonded), copper or brass. Poly, rubber, cast iron, galvanized and plastic is not allowed inside the house in most (if not all) areas . CSST needs to be run through "strike plates". Copper and brass are not allowed if the gas contains more than 0.3 grains of hydrogen sulfide per 100cu ft (generally referring to propane).

There's also a host of other bonding, support, shut-off valve and drip-leg regulations.

I came to a stop sign and a skanky tweaker chick in a tube top climbed out of the brush and propositioned me.  She looked like she didn't have any teeth so I counted that as a plus.

Time for a story.

I grew up in the country.  A neighbor had a couple of oil wells drilled on their property, either through a lease or sale of mineral rights.  They had the right to use the head gas for their personal dwelling.  The well was finished in the fall, so they ran some polyethylene gas line on top of the ground, into the basement, through the basement window.  They planned to bury it in the spring. 

That winter we had a bad case of freezing rain, on top of a about 3 feet of snow.  This put the weight of the snow at dangerous levels, so people were shoveling off their roofs.  The man of the house unknowingly dropped a large piece of ice on the polyethylene gas line.  The gas flowed through the basement window, where the polyethylene gas line entered.  However the gas was not there for long, only long enough to hit the furnace pilot!  We lived 1/2 mile away and the explosion rattled our windows a bit (granted, we did not have modern, tight, double insulated windows).  

They were extremely lucky.  The kitchen was an add-on.  The explosion separated the kitchen from rest of the house.  No one was killed or seriously injured.  There was enough snow on the ground such that the man who was blown off the roof had a soft landing with minor injuries.  The rest of the family was in another part of the house and they escaped relatively unharmed.  I cannot remember if they were treated at the hospital or not.
I tried not believing.  That did not work, so now I just believe

Just run garden hose.  To hell with all those building codes and material certification standards and proper sizing charts and such.

Bad experiences come from poor decisions. So do good stories.

I'm sure it has been done.   What I saw with theft of electricity, I would bet the garden hose is not the worse.  Roly

Quote:Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links. It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and insulation for high tension (high voltage) electrical cables. It is also used for natural gas and offshore oil applications, chemical transportation, and transportation of sewage and slurries.

I would guess the reluctance to use this material in a house would be the fire threat from leakage caused by damage or poorly done connections.

I should have paid attention when they fused the new connection in my backyard.

BTW, my line was only about 6" deep. I am glad I never put a shovel into it.

Yep I think the OP wanted a certain response to the question instead of what might be safe.

When I built my current house eight years ago the plumber used some kind of flexible plastic tubing or pipe. On each end before it came out of the ground he transitioned to metal.

That's poly gas pipe. Only rated for the utility side of the home... underground, not exposed.
