I have a difficult problem with a Volvo XC90 V8. Not your typical car to get plumbed, but it needs a bit.

The issue is the low pressure side of the power steering, the line was damaged by a Volvo dealer and is only now leaking.
Due to the excessive cost to replace the line, we attempted to get back on the road
with a quick cut & hose clamp repair but that's failing and needs to be done correctly.

What I wanted to do was pick up the proper fittings and tubing from Parker in Phoenix,
but upon measuring, they found the cut piece is 12mm. Is there such thing as metric parts?
