Hey guys, I am in teh process of setting up a new Quincy 65 gallon compressor. I have one lingering question. Coming out of the compressor is a 1/2" shut off valve. I am planning to run hydraulic hose from that into my filter/regulator....my question is this...how do I tighten the flexible hose to both the shutoff at the compressor and the filter without twisting the hose? the filter/regulator are plumbed together with copper tubing and I have fixed them to the wall...all of the hydraulic hose I can find has fixed NPT threads at ecah end...I imagine it will take 4-5 complete rotations to tighten fully...how does one account for that twist in the line??

Union?

Yes, union as stated is the answer. I would suggest one rated at 250 psi or 300. Not the imports from box stores which are rated at 125.

You'll need a swivel fitting on at least one end so it is serviceable. Like a JIC swivel. If you know your NPT sizes, just go to your local air/hydraulic shop, its a 5 min job for them to make you one up and supply the fitting.
Alternatively you could use a Teflon lined stainless hose from a semi truck compressor output with it's matching fitting. You could make friends with the counterman.
The air/hyd shop will be cheaper.
Ok, again, I am struggling to find a proper union it seems that the swivel unions I can find are at closest NPT on the male side and NPSM on the female side, I understand that is probably workable, but is there a better option...here is an example of what I can see:

The NPSM will work fine provided the male you connect to it has either a chamfer or is of large ID.

Have you consider an air hose whip for semi truck brakes , that's what use,much cheaper and premade.

One option is a pipe union and one pipe ****** at the filter regulator. I am not sure of the regulator NPT so I do not know if you will need a pipe bushing somewhere. Or, As jeepinherdeep suggested, bring your hose to a hydraulic shop and they will sell you the proper male and female fittings you need. (You need both and they should be matched to each other.)

Just go to a place that makes hydraulic line with a fitting that will turn on the hose. Take or know what sizes you need on each end

I had the same problem and ended up installing a 1/2" NPT union from Lowes.
Edit: Here is the link to the union I bought.

Here is what I got...it will a require a male to male adapter, but that is not a problem for me as they are available at my local ACE...the other stuff was not...
