D&O Manufacturing in Helenwood TN makes and sells air hoses. I have bought from them on multiple ocassions. The one product that I like best is their 1/4" Hydro-Air hose. It is smaller in diamerter than rubber hose and more flexable too. I can put a 100' piece on one of the HF reels ($21.99) that comes with a 30' piece of rubber hose on it. Currently I have ordered a 100' length with 20 brass male inserts and 20 brass ferrule. With these I can make custom lengths for use in shop. This hose comes in both red and black. Also currently they have on sale -50', red rubber, 1/4" hose for $8.95. For this you can also order ferrules and inserts.Their phone # is 800-752-0885. Web address is www.dohoses.com. If you don't own a crimping tool, don't worry. A flaring tool block can be used, or you can bore the right size hole in a piece of 1/2" steel. Cut block of steel through bored hole. Insert male insert into hose with ferrule on it. Take whole assembly and put in vise. Tighten vise to crimp ferrule. Looks just like "factory" and no hose clamps to catch on everything.
