Hose for compressor tank to hard line?

[snowphun]

I'm going to run 1/2" copper for a few drops in my garage this weekend, I think I've got a handle on it after reading many threads. What I am unclear on is how to connect my compressor to the start of the hard lines. I need about 4' of hose, is this something a HD would have or do I need to source it from a specialty vendor? I'm hooking up to a Husky C301H which appears to have a 1/2" female outlet.

Thanks.

Lots of people use a hydraulic hose

We picked up a 3/4" hose and quick connect fittings from the local hydraulic shop. It wasn't too expensive and sure looks like it flows enough!

 

[Cyberbear]

Use any type hose rated for the pressure and use a union and shut off ball valve to do it right.

I used a 1/2 inch quick connect and a 1/2 inch rubber hose whip to tie my compressor to my pipe on the wall. I used Milton type G quick connects.

X2... Working just fine for me...

I had the local Hose & Rubber Shop make me to go from compressor to Regulator and then one from Regulator to Manifold. Cost me around $10 for both, Parker Hoses and Fittings. 300 PSI

I used the Gas Yellow Teflon on the threads. works great.

Need a bigger guage on the ARO IR Set up

My local Lowe's sells air hose by the foot in the same area that the 1/2" hose barbs, hose clamps, and pipe unions are located. Ball valve at the tank, union, hose, union to the hard lines. Hydraulic shops are another option. Your local compressor shop can probably hook you up too. You might consider extended the hard line closer to the compressor so you can use a shorter hose.

why not use fittings and make it all hard line?
mine has been that way for over 30 years with no problem

 

[Desoto61]

I went fancy when installed my compressor and used a braided stainless flex hose, but it was a pretty fancy compressor so I figured it was warranted.

McMaster-Carr

But they have lots of other options if you think that's overkill.

Hydraulic hose for the win...

op check out tractor supply if you can't get to a hydro shop. I got a 2 footer hose off the shelf. my compressor shakes my whole garage as its on a raised wood floor so I wanted to isolate that from my piping. 3 years works fine.

Vibration can cause stress damage on the compressor and lines. Isolating it from the piping and structure is a good idea.

Use NEW hydraulic hose.

 

[stonesfan68]

Use some sort of flexible hose for the best results. Others have mentioned hydraulic hoses, and here is an example of another type:

Grainger 4YFV4

I got mine from TP Tools.

Just FYI. compressors get HOT! that line from the compressor will get HOT! the pressure rating is not at 100 degrees f. I tried some of the fancy 300 psi air lines from lowes. I would get about 6 months out of them before failure.

Hydraulic line is the only thing I have used that has survived.

A rubber truck air hose...Any truck dealer will have them in stock

 

[BearsFan315]

our local advanced auto has a hydro shop for making custom hoses, also looked at TSC, harbor Freight, Northern. what i paid was far less then what they wanted off the shelf.

Are you thinking of the discharge line from the pump to the tank? The OP is asking about the tank connection. The line from the tank should not be hot enough to destroy 1/2" or 3/4" standard air hose. Many people connect a cheap PVC hose directly to their Husky or Cobalt compressors to run their impacts.

Local big truck supply. I used plastic truck airline and compression fittings for mine. Total of 7 dollars worth!

Thanks for the suggestions, my local hydraulic hose shop took care of me for small money. Turns out that was the easy part, I'm now struggling with the fittings off the copper pipe. I ran 1/2" pipe, I want to put on some 1/2" quick disconnects. I've since learned that 1/2" copper is inner diameter, 1/2" air hose fittings are thread diameter so they aren't going together. Looks like 1/4" copper fittings would get the job done? Of course HD/Lowe's doesn't sell hardly any 1/4" stuff so I'm off to a proper plumbing store to see if I can figure this out.

I am doing this all wrong?

 

[PeterT]

Connecting my 1/2 black pipe compressed line to a hose reel requires a similar lead hose? Do they make one, or can someone recommend one, that has a 'nut' on it so it can be tightened/taken off without having to take apart all the other pipe? I don't think I would want to put a union there. I have 1/2 black pipe and my inlet on the reel is 3/8. Thanks!

^^^ Yeah, I scored a few similar to that at the plumbing supply shop, though he was not impressed with my project and didn't have any male versions. I guess I'll need to settle for a 1/4" ball valve right at the tank, feels like such a restriction on the air flow given the 1/2" plumbing elsewhere.

 

[ZRX61]

I used that clear plastic hose that has the white mesh embedded in it. Still good after 20 years...

Won't this work for you?? http://www.homedepot.com/p/NIBCO-1-2-in-Copper-C-x-MPT-Adapter-C604/100342945

And a 1/2" ball value

What size hydraulic hose fittings/quick connect did you get? I am not an expert, not an engineer, and haven't even googled flow recently, but I'd vote keeping your line size the same at the compressor. We may have used 3/4" off the compressor, I will have to check for you next weekend. The hose shop suggested it and the price was reasonable so we got it. 5yrs later its still working great, its been disconnected a handful of times. Very high flow.

 

[Crusarius]

I may be misunderstanding what you are saying but If you are trying to feed a 1/2" line through a 1/4" line you will not have any sustainable flow. You will get a short burst until the pressure in the lines drop. you cannot feed a larger line with a small orifice.

No, those are 1/2" inner diameter, the outlet off the regulator on the compressor is 1/2"x20, which is 1/4" inner diameter. A 1/4" ball valve is tiny and seems like a bad idea.

Crusarius: yes that is effectively what I'm left with here. I know the Husky c301h isn't professional grade but it is indeed 1/4" output like most compressors I've looked at.

I missed that you had a c301h. That is going to be a bottleneck.

My cheap craftsman compressor had a plug in the side I tapped into and ran 3/4" ID hydraulic hose to 3/4" black pipe. I bypassed the regulator and run direct tank pressure. Have never had a problem since it is rarely about 125 anyhow. when it is above 125 it doesn't last long.

I still have the regulator there that I use when I need to plug my nail guns into it.
