8mm Copper Pipe for LPG, insulated or plain?

[56337]

Hi Guys,

I am looking to fit a bullfinch external BBQ point to the Motorhome. My question relates to the 8mm copper pipe. On a previous caravan it was your bog standard bare copper tube. On my current Motorhome it is covered in black insulation, not sure if it's powder coated or plastic.

What is the purpose of the black coating and is it easy to strip back to attach compression fittings and olives?

Thanks.

I believe 8mm plastic coated is generally used for domestic heating oil pipelines buried underground, from your tank to your boiler. You can use either, just cut the insulation back. I used plastic coated because I had some left from a boiler install.

I used uncoated/insulated just slid the flexible plastic conduit over the top.

Carefully score with a Stanley knife. Try not to deeply score the copper, it may weaken it if it's susceptible to any vibration.

If the tube is covered you can't see damage or corrosion - I'd just use bare copper

No definitely copper, you can see about 10mm where the union is fitted.. That's on the length I want to tee into but your right, elsewhere there is uncoated steel also.
