6mm tubing to 1 1/2inch PVC female, how?

Hi, i've got a hot tub that has a rather odd issue, whoever installed it originally connected the 6mm high-pressure tubing directly onto the air bleed valve - instead of the 1 1/2inch female around it, effectively making it impossible to open completely without breaking the 6mm tubing.

I don't think 6mm tubing is very commonly used for hot tubs, and I'm no plumber - I certainly can't find any 1 1/2 inch female to 6mm threaded tubing port adapter. How exactly do I connect the 6mm to the air valve properly?


Good side, in working order.


Bad side, directly connected to the bleed valve that turns, torquing the wire.

6mm is so close to 1/4'' they are cousins
