Plumbing Help. Copper to Hydraulic

[EB.Bldr]

Ok...I've been staring this screen searching thread after thread looking for fitting sizes for copper to hydraulic line for about 1.5hrs. Even looked through all 50 pages of 'Show us your compressor' thread and maybe I missed it.

What I'm looking for is fittings to attach 3/4" hydraulic line to 3/4" Copper. I've called Napa and they can make the line, but need to know what fittings to put on. I asked what types were available and the rep could not advise me as he needed to "see" the machine it was going on...Grrr another story all together.

I know I'll be using 3/4" copper to 1/2" NPT for the air couplers, and assumed I would use similar for the fitting to the compressor. But...dont know what fitting will go between that to the hydraulic hose. Additionally, I need to have the pipe plug on the side of the compressor drilled & tapped, so knowing what fittings I will need will effect that decision aswell.

Can someone PLEASE help me out? TIA

What hydraulic hose?

Re: Plumbing help please.

If you took a 3/4" female adapter to the napa store, could they put a 3/4 male adapter on your hydro hose?

See I'm not sure they will have a fitting that will be straight NPT, I don't think they can mix. I would take a fitting and see what they have. I'm not sure why you are using hydraulic hose.

Re: Plumbing help please.

Dave 3/4" should be fine if you are using 3/4" pipe . My question is why are you having the plug on the compressor driled and tapped ? Mine came with a 3/4" hole tapped in the topside of it and I simply came off of that with 3/4" black iron and then hooked that to the hose .

Re: Plumbing help please.

What hydraulic hose?

Running an 11" Piece between compressor and copper to reduce vibration in the hard line.

 

[ratdoggy]

They can make a hose that's just pipe on one end and a truck air hose swivel at the other end. Basically what you want is a air chamber hose for a truck. That's something almost any truck place can make or have on the shelf.

Well the plan is to T in where the air will come into the copper. Up to the air line, Down to the moisture trap, and horizontal to the compressor. The fitting I found was a sweat on end with Female 1/2" NPT. This is what I will be using for attaching the air couplers. Similar to attached pic of someone elses setup. Thx BTW...

I was thinking it would be fine to use this for the line comming in from the compressor, via hydraulic. I am open to what ever end will work on the line...I just need to know how to attach that to 1/2" NPT. The middle man per se.

Mine did not come drilled and tapped. While it is a portable unit, it will be in a permanat spot. Pic included.

I used a piece of that transparent plastic tubing that has the white braids inside it & a hoseclamp at each end. It's been on the compressor with no leaks for 15 years...

1) Do you mean mean NPT, 'pipe', on one end?

2) The swivel type fitting is what I'm looking to find out about. What size/type of fitting would that screw to?

I'm not against something like that. Is there a rated type tube I should look for? I would assume a 1/2" NPT barbed ****** would be easy to come by.

 

[Frank The Plumber]

I think they would be able to do it, if not you could use a pressure pump isolator, but that is going to be pricey. I don't know how ZRX is using a bit of that poly hose for 15 years, I thought it dissolved after 5.

 

[54FordPanel]

I just used a braided line made for connecting hot water heaters, 3/4" NPT. Cost me $12 at HD. I've posted a picture of it before, I will look for it.

 

[Frank The Plumber]

Those are not rated for much pressure. They look tough but they are not.

 

[EB.Bldr]

Game on. THANKS!

 

[ZRX61]

I just used whatever it is they had at Home Depot. It's discolored a bit over time....

I have the same thing as 54Ford Frank havent had a problem yet . Granted I dont go over 130#'s of pressure on my system either .

[54FordPanel]

Here it is. Truthfully, I am not worried about this thing failing whatsoever. It's rated way higher than the 150 lbs that's in it. (I don't remember exactly, but it was higher)
If it ever fails, I promise to post it.

 

[Frank The Plumber]

I guess if you put it in a spot where it can't hurt you it would be OK. Those type of lines get brittle and fail on toilets and sinks all the time. At least you won't get wet.

 

[kams1973]

You don't need to drill and tap that plug. Simply remove the plug and install appropriate plumbing.

 

[Submarine_Sailor]

That tubing that ZRX61 is using is only rated for ~140 psi. It starts to bulge around 130 psi. That is, if it's the standard stuff you buy at Home Depot or Lowe's. My compressor runs 200 psi, so I wouldn't use one.

 

[nate379]

300psi air hose, in the size you want, with 2 push-locks on each side. What's so hard about that?

Or you could just hard pipe the compressor right to the copper. Hell my Dad's setup has PVC hard piped to the compressor. Hasn't had an issue with it and he did that over 15 years ago. (I bet that will start some posts haha)

Picture if you don't now what I'm talking about.

[akdiesel]

I would suggest JIC swivel connection on both ends of the hose and get some 3/4" JIC fittings for the 3/4" NPT female brass fittings on you tubing.
The JIC fittings are a better seal than the Union type fittings and it also allows for quick connection to both ends with out having to turn the hole hose.

Yes.....Just remove that plug and install reducers as necessary.....I think mine has a couple to reduce it down to 1". Mine is then reduced down to 3/4" to a 3/4" hydraulic hose I picked up at Northern Tool for about $15.00 (I think it's 24 inches long) which then goes into the black pipe setup.

This is deff what I was looking for initially. I will talk to Napa tommorow and stop by ACE and see what they have. Pic for you AKDiesel!!

Thakns 54Ford! I'll be looking for what is available at HD tomm. Will be easy to spot fittings once I find the hose.

Its going in our 'storage' room away from everything so what ever goes in there it should be safe none the less.

This one I have considered. The thing is thru research it seems that the threads on the plug are tapered to a certain degree and the adapters to get it down to 3/4", or atleast the inital 1 1/4" is not going to be tapered. I'll look into it further.

My hope is to keep the flexibility of haveing a mobile compressor mobile. But I figured drilling and tapping I can just install a pipe plug if it really needs to move. Deffinently keep it as an option!!

Dang perfect!!! Now to find a TS. I think there is one in Jeff City. Thanks

OOPs wrong picture that's my wife at Halloween. I clicked on the wrong picture. Here's mine. Don't mind the air cooler (don't flame me it's going bye bye)
That's a made up line from a truck place. I used to work in the parts dept.

Almost any industrial supply would have it or can make one!!

Would they do it for $10.00?

Probably more but it depends on what's near you. Most decent towns have a truck place.

Somehow I didn't think anyone would bust my balls about my mistake

Unless I'm missing something, I think you're horribly goofed up.

Pull the plug out of the compressor, it's going to be pipe thread. Now, get the size hose you want with JIS connections on it. Get the appropriate male fitting with the JIS on one side, and pipe on the other. Use whatever pipe bushings needed to reduce the bung in the compressor down to the size needed for the male JIS fitting. Do the same on the copper side.

You can also get AN stuff online, and do the same thing. I did.

Now if I could just get time to finish the damn thing...

Edit: For your purposes AN/JIS is the same thing and interchangeable.

I may be goofed for sure. But to clarify the plug on the side of this compressor has a rubber o-ring on it. And the research I dug up here...said...the threads on that plug are tapered and pipe threads wont seal. Dont know for sure. Cant find that thread.

Thanks for the tip on JIS to AN. I have done work with various plumbing using SS line and AN fittings. A snap to work with. Assuming -8 would be close to 3/4 but I can find that out.

Yeah...I saw your compressor on another thread...incredible!!!
