Copper tube is not allowed in the states either. It is too soft in terms of abrasion resistance. Copper tubing work-hardens and becomes very brittle especially at the flare. The British have developed what they call "copper brake pipe", which seems to be a seamless tube but it is made of a copper alloy but again not as good as what can be purchased today. Use good old Bundy Tubing with the proper flare and fittings to CYA.
