Compressor piping or hose Question

[MinnesotaDaveChalmers]

Terry, I have that pliers for automotive cv boot clamps, where did you get your small clamps?

Standard at parts stores?

Dave, I don't know the name of the clamps, but I get them in bulk from my local industrial hydraulic supply. I think they're quite common. For your clear braided hose you need #13 for 1/4ID , #14 for 5/16ID and #15 for 3/8ID.

I'll look in my Acklands Grainger catalog tomorrow unless someone else knows what they're called.

I used high pressure rubber hose for my whole system.
Use barbed fittings with 3/4" hose clamps.
No leaks in over 1o years of use.
No need to get a hose made up, buy enough hose and cut it to size and the same store should have the barred fitting too.

I'm not the safety police and I'm certainly not one to tell anyone what to do but....

I have a friend who worked in an auto body shop recently where a geared hose clamped fitting on an air hose let go. The sharp edges of the clamp fortunately missed his face but cut up his arm and leg bad enough to put him on permanent disability.

Similar systems installed properly and operating at lower pressures may be okay but I can't say for sure.

Then the shop did one of two things or maybe both...

One - use the wrong size fitting for the hose being use. The barbed fitting should hold the connection by itself, the clamps are just a safety added thing.

Two - tightened the clamps,too tight. If the screw type clamp is tightened too much they will cut the hose, defeating the Barbed fitting and a screw clamp can be twisted and break. I have seen the screw clamps on radiator hoses cut through the hose and leak... all in proper install.

Again, over 10years with no failure, ran 175 psi in system without problems.

I was wondering if folks were using the typical hardware store geared type hose clamps....but I see there are risks.
I did not see any comments about soldered copper fittings on half inch copper pipe.
It is not like it will be a solid cionnection because at both ends it would be attachinh to hose which would be loose so vibration not an issue. (reel has short hose coming it off it to connect compressor end to and compressor has short hose (quick connect) for tool or reel connections to come off ............has anyone fed their garage with copper soldered pipe ? If they have then obviously good soldered connection can handle 150 psi ....thoughts

Copper is the way to go, if you can afford it. When I built my first inner cooler for my shop air system, the rolled copper tubing is good for 600-PSI.

I used the the brand that was sold by the store I purchased the barbed fittings, they appeared a little wider.
Dont over tighten.

Copper Pipe / Soldering... Too much trouble, equipment to solder, then you still need to hang the stuff.

check out the copper pipe psi rating, if the pressure is ok for your compressor and you want to solder all the connections... go for it.

I didn't see the setup personally, but I suspect you are right.

TSC has 1/4" NPT hose ready made in short lengths. Also have other sizes available. They will work for your air compressor.
