is there a swivel end for rotation of the console?
No there is no swivel end. I bought the hose for a pressure gauge only, not a console. The gauge provides a swivel as part of the casing. A console should provide the same functionality because the console houses a pressure gauge. I'm not familiar with any consoles where the HP hose connects directly. Check yours. I've always seen them connect to a gauge inside the console. Hope this helps.
I haven't seen a swivel yet but I have seen 90's.. I don't think they will make one due to the the extreme high pressure..
Yes, the fittings on a High Pressure hose are standardized and they contain the female threaded part of the swivel.
However, the hose does not come with a new "air spool". That's what they call the tiny pipe with two O-rings on it that goes inside the swivel joint and makes the whole thing work. The air spool is only about 1 cm long and a few mm in diameter, so it's easy to loose or overlook. Your local dive shop will have them or you can try "google shopping". Don't just reuse the old one, unless you are sure it's in good shape. (meaning you KNOW your LDS replaced the O-rings the last time they serviced your regs. Some do, some don't, so ask if you aren't sure....)
It's not rocket science, but technically you are servicing your regulator when you pull the air spool out, inspect the O rings and check the finish on the surfaces they slide against, so be careful and test everything before you bet your life on it! If you have any doubts, ask the service department of your local dive shop. (If they lay a guilt trip on you for inspecting your own stuff, find a new dive shop.)
Note: If the air spool is missing, or missing an O-ring it's really obvious. The swivel will leak a LOT of air.... If the O-rings are tired or the surface finish is bad, the SPB swivel may leak a smaller stream of bubbles and may be hard to turn, but don't wait for trouble to start.
While you are at it, check your SPG. Hook it up to a full tank, open & close the valve and breath it down slowly. The SPG needle should drop smoothly as you breath in. If it hesitates or jumps around, or still reads 200 PSI when the tank is at zero, then it's time to replace the SPG too. (If you use high pressure tanks, your SPG is more likely to read high over time)
