This hose is "specifically" for the gauge type as shown on my regulator set in the last 3 photos and requires the copper seal, R50457 when assembling. If anyone buys this hose, I will put in a couple of the copper seals, since I still have a bag full of them.

So, if you are still using these gauges, like I am, and you need a hose, then I have one here.

Extra info - The threads at each end of the hose are not standard dive industry threads. They are actually G1/8"

And the hose is approximately 95cm long.

Obviously, I am only selling the HP hose, and not my regulator set.
