I,m reading thru this thread and it reminded me to point out that theres a great many air compressor hoses sold by various auto parts stores and other vendors that are not worth the cost.
I purchased three 50 foot air hoses from HF ,when I bought my small compressor.
Two were loose rolls and one was on a retractable reel.
In my opinion I should have spent a bit more and got better quality hose, both the loose coil air hoses developed splits or blow outs and the end fittings leaked within months.

heres a few links ... 69580.html ... 69265.html

The retractable hose reel lasted about 8 month then the fittings stated leaking.
I repair those leaks by cutting the ends off and installing new fittings but within months the hose split.
So within a year they all went in a dumpster.
I went to the local hydraulic supply and had a couple 75 ft, long 1/2" inside diam. black, air hoses rated at 300 psi fabricated.
Those hoses are about 7/8" in diameter while the other HF hose was about 5/8" in diam. and noticeably lighter in weight.
Ive been using those newer , and larger hoses, for several years and although they cost me about $76 each at the time I purchased them, its proven to be a great deal better in my opinion, to spend a bit more up front and not have the hoses fail and have to stop and make repairs or a trip to buy a replacement, and the 1/2" inside diam, hose seems to allow the air tools to run a bit better.
Keep in mind I don,t have near the compressors or shop grumpy has my compressor rated at 2hp but its on a smaller 30 gallon holding tank, and it has a hard time exceeding about 125 psi , which is fine for running my air ratchet but not much else.

the subject of compressor tank internal corrosion due to constant moisture in the compressed air contained in the tank came up, and thats a valid concern as it will eventually weaken the holding tank strength.
obviously the first line of defense is to drain the tank at the start and end of each time the compressor,s used.
the earlier posts that show how heat is removed from the compressed air and water trapped before it enters the holding tanks goes a long way towards reducing the corrosion, but theres a spray corrosion reducer product that can be used to coat the inside of the tank, and a 2 lb Magnesium ANODE with a connecting electrical cable that can be used to provide some additional electrical protection, if the anode gets buried a couple feet down in damp soil ,outside the shop, the cable run thru the wall to the compressor and the cable clamped firmly to the compressor tank it will provide some galvanic protection
