What Size Air Compressor Hose Do I Need

In my experience, increasing the air hose size adds a little fleck more air and power delivery, but nothing too noticeable. If you increase the fittings, ensure that the compressor can handle it and keep up, merely in your case yous have a 29 gallon, which should be fine.

Using fittings and hoses with a small internal diameter (some cheap fittings) certainly reduces the power of an air tool. Specially the curly hoses you become with a lot of compressors are bad, they're pretty much for inflating tires and such. A straight hose and decent fittings in either size should be fine though. 🙂

I do have direct 25 foot iii/viii″ hose (and fittings) but when Ive used the Touch wrench on axle nuts, crankshaft, exhaust etc… It doesn't seem to have the power to remove them without prolonged and repeated contact and without using heat and/or penetrating oil. Well, I judge the only real test is to change over to a larger size and see what happens. I was just wondering what most mechanics used… if virtually use 3/8 with no problem, then perhaps my compressor is too small or under-powered or perhaps I need to upgrade my impact wrench. Cheers for your input information technology'southward appreciated.

I just checked, all my stuff has 1/2″ fittings though, so maybe 3/viii indeed isn't enough? Not sure.

I call up there is already an ETCG video about the fittings..

Maybe this video will aid:

Great video. Answers all my questions. I had tried YouTube previously merely I didn't know what to search for. -Cheers.

The longer and smaller the hose, the more pressure drib at the tool.
Yous likely have a unmarried stage compressor that might have max air pressure of 125 PSI?
A dual stage compressor can produce over 175 PSI.

I have an old unmarried phase 5HP 60 gallon compressor. The outlet and outlet hose are 1/2″ and goes to a filter/regulator/oiler that are all i/2″. the outlet of the oiler is a 1/ii″ quick disconnect, but I have an adaptor to connect up the 3/eight″ hose which is what I normally employ.
I have a cheap impact that works OK, just dosen't loosen actually tight stuff, and and so I have a nice Snap-On impact that works way better at the aforementioned air pressures, so the quality of the tools matters and also make sure to keep them oiled.

My compressor is a chugalug driven 2hp cast fe single stage with a max of 150 psi. I think my craftsman bear upon would perform much better if I tin can verify that I'yard supplying the needed 90 psi at the tool. I'm gong to try and find out how much loss I have and meet if I can compensate (as per the video). I'll post my results when I end. -Thank you for your input.

Well here are my results then far:
With a 50 foot three/8″ hose and ane/4″ fittings with static pressure of 90 psi at the tool (bear upon wrench)… the working pressure dropped to ~30 psi.
With a 50 pes 3/8″ hose and iii/viii″ fittings with static pressure of 90 psi at the tool (affect wrench)… the working force per unit area dropped to ~65 psi.
Then increasing simply the fittings lonely doubled my working pressure. In society to get a working force per unit area of ninety psi at the tool I had to change my static pressure to ~126 psi.
Next I volition upgrade my air hose to 1/ii inch and postal service the results.

Also some food for thought, some high flow 3/8 fittings will make a large difference as well. The internal port size is a major difference betwixt inexpensive and the good fittings

Just a quick food for thought . It probably makes a large difference equally to how much air the tool uses . A modest 3/eight″ air ratchet & the smaller hose & fitting will probably fine .

Only you were asking about a total size 1/2″ affect wrench .

For my DIY shade tree mechanicing , I utilise a Harbor Freight 1/2″ electric bear upon wrench . Information technology is big & heavy & bulky & non too handy . Merely so far it has worked pretty well . And easier to string an extension cord . And I seem to recollect it cost $ 40 – $ 50 .

If I had an piece of cake way to go an air hosr to the front end drive , I would use my ancient one/two″ air impact . If it still works .

God bless
