Yellow Pex or CSST outdoor NG generator
Which is better more flexible for a 35 foot Ng line to outside for a portable generator. I see different types of Yellow Pex, it needs to be flexible at the generator. I don’t know anything about this. It’s a pro converted Honda Eu2200 that came with a1/2” propane tank line. I have the NG regulator. Not using Black pipe.

You should use black pipe, or galvanized pipe and have a flexible connector at the generator.
If you use black pipe it should be cleaned and painted.
I've never seen pex used for natural gas. I have heard of using polyethene but it needs to be 100% buried and not exposed to sunlight in any way. Polyethene also cannot enter a building from what I recall, so you're still back to black pipe or galvanized pipe.
If you don't know anything about this why are you considering doing it?
EDIT : I see this is a portable generator.
You would still need a hard piped connection at your house, but you can probably use a natural gas hose with quick disconnects as used on gas grills. But again, this needs to be installed by someone that knows exactly what they're doing. This is NOT a wing it and hope for the best project.

This is how gas is done around here. I used this kit for my shop supply from the house.

They sell quick connect kits for those, probably similar to ones for natural gas grills. You still need a proper gas service to the quick connect, you should not run the yellow, or the CSST directly to the unit. You should install the new gas line properly, size for the unit, yellow underground with proper risers for coming out of the ground on either end, and black pipe built out from each riser as needed, valves for service, and then attach your quick connect kit between the black pipe and the generator, if your gas service is already properly regulated you won't need an additional regulator. Consider sizing the new gas line for a whole house unit as you may wish to upgrade in the future. and please contact a pro to install this, messing with gas can be a big safety issue and sometimes you just don't know what ya don't know.

Is that polyethene?

looks like it, SDR-11 MDPE gas pipe more than likely. We sell mountains of it

I like that it comes with the metal ends and all. I need to run about 100' of underground gas pipe in the near future, probably 1". That would come in handy.

The pipe is inexpensive, the risers on the other hand are pricey. there are a few styles available, and those poly couplings shown are actually pretty decent. We started selling them about 3 years ago after they had been out in the market for a bit. Less expensive than the big metal compression couplings and you don't need to wrap them.

Pex is not allowed on gas. CSST is junk. I would use pipe or poly. Gas is dangerous and has to be treated as such

We just call it "Poly-Pipe" all NYS utilities use it. If equipment is within a short distance from home or building, hard pipe is the way to go. CSST and poly-pipe need protection. Mad Dog

Hot_rod .. yes that is what I thought was pex. What is that pipe ? that’s what I was thinking. I could not not see a name or link.

Polyethylene gas pipe. It can only be used underground, and you have to use the steel risers for the connections.
Supply house.com has it

Yes it is PE. Same plastic the use for the large main lines in the street.
We had a second explosion recently where old steel gasline corroded and leaked into a building. PE should be more tolerant to seismic activity also. If that matters.
The box stores sell it in those kits.

thank you.

Which is the reason they don't like inside meters. Pipe in the street breaks and the gas can't get into the building.

pex is PE, the X means it has been crosslinked

True.
But that crosslinking makes a very big difference.

most all the pipe that get buried is PE these days. PERT is just PE raised temperature tube used for hydronics.
Water service lines, NG lines , irrigation piping is PE. If there were a value to having it cross linked I imagine they would do that?
