What material should a gas flex line be made of (gas range converted to LPG)?

Question

We live in an apartment overseas which has been outfitted with full-size American appliances. The gas source here is LPG, so our Kenmore range was converted (how well the conversion was done is anyone's guess). We have had a gas smell in the cabinet adjacent to the range ever since we moved in, and while our maintenance guy has tried various methods to seal up the gaps, the hose itself is vinyl, which I'm assuming is leaching gas and causing the gas odor. So, can an LPG range ever be properly plumbed with vinyl tubing? Or should I insist on metal?

Answer 1

I have not seen vinyl flex gas connectors. Some of the newer brass ones have a plastic coating. Gas companies are using a plastic type pipe for underground lines but they have special connectors and tools that need to be used. I would request a metal connector. Conversions of gas appliances has been made easier over the years. Most include merely flipping the disk inside the regulator over. I have one of this type. Didn't even need to change burner orfices.
