thats cross linked polymer material, very heavy, tough and
expensive..used because it wont corrode, crack or break ...and it
bends...its a fast install..... but it has to be underground. Not
suitable above ground because it melts in a fire.
Thanks. I guess that's what they used in the underground installation that
But, I have a 15-foot (+/-) bright yellow "plastic?" flexible gas supply
line in the basement of a property I own. It was installed a few years ago
when I had a new gas boiler/heater installed to replace the oil-fired boiler
for the cast iron radiator heating system in the home. So, I know these
exist, and I know they are code compliant. Some of the links I found when I
did the Google search seemed to show the same type of bright yellow flexible
gas supply lines for in-home use.
