View Full Version : Rubber Hose ? to Hard Air Lines
I just bought a 60 gal compressor and the outlet at the tank is 1/2". I want to plumb a hard line from the compressor to the other side of my garage and I would like to go with 3/4 copper.
The question I have is about the flex line that needs to be placed between the compressor and the hard line system. What should I use there and how should I do it?

My air system has worked fine for the last 22 years with the hard air line plumbed directly to my air compressor (no flex line). It is a good idea to use a plumbers quick coupler at the compressor outlet.

home depot or any plumbing store has an adapter that solders on the 3/4 pipe and has 1/2" threads on the other end, then just use a short piece of hose with the apropriate fittings and your all set.......Vinny

Compressor manufacturers do recommend a flex hose from the compressor to the hardline. You can get away without it, but why chance it. You can order one from Grainger made specifically for compressors. You can also go to a local high pressure hose maker and have one made to your spec's. Look through your local phone book. You will still need some plumbing fittings to go from 1/2" to 3/4", but that's no problem if you have a Lowes or Home Depot or local hardware store around. You shouldn't have any problems if you use a flex hose, but you may have problems if you don't.

I did exactly what PhilV described about 15-18 years ago & haven't had any problems. I also mounted the 80 Gal. vertical tank on 1/4 inch steel discs on top of 3/8 inch rubber discs, (conveyor belt) then bolted everything to the concrete floor. Bob L.
I had the local hardware store make me a hydraulic hose. It's overkill I know, but it's what I could find.
