Whale Blue/Red MDPE Tube 15mm?

Any of the push fit stuff is more than adequate, the only real advantage of the Whale stuff is that it is easy to identify the hot and cold system, perhaps that is why you like the idea? Generic MDPE tube can be had for peanuts in coils, 2m & 3m lengths. I use JG speedfit because I like the final screw for security and the fittings range.
