What size air hose and air hose fitting do you use? I currently use 3/8 hose and I/M 1/4 fittings, i heard that if you use the 3/8 t fittings you will gain a lot of power, I am using basic air tools. I was wondering by useing my set up if I was choking the power, and I thought I would ask before buying all new fittings. Thanks

P.S I have a175 psi max craftsmen compressor I use my 1/2 drive craftsmen 600 psi max impact the most.

 

Anyone?

 

You'll gain a higher CFM with a larger sized fitting. Most air hoses for home use are 1/4-3/8 with 1/4 fittings. Unless you are running air tools that require high CFM, you may not need them. You can always pick some up and try them if you want. Sanders, HVLP spray guns use a lot of CFM.

THe big thing to look for on compressors is your CFM. Any air compressor can kick out high PSI, but few have the CFM to back it up.

What CFM am I looking for out of my compressor? what is athe range that I want to be in? thanks

 

Which model of compressor do you have? Each compressor is different. Generally they'll make a horizontal and a vertical model with the same compressor, just different tanks. I have a 30 gal upright (space consideration). Could have gotten the same package with a 33gal horizontal.

Compressor Specs

That's my compressor. It's 8.6 CFM @ 40 PSI and 6.4 CFM @ 90 PSI. Max PSI of 150.

The 175 PSI leads me to believe it's in the professional line (i.e. black w/gold lettering.)

1/4" fittings should be good for most home stuff. Up into the sanders which suck air like you wouldn't believe. All of the tools should say they use X.XCFM@YPSI. Usually 40 or 90 PSI.

Most tools also only have 1/4" fittings anyways.

Yeah it is the pro model,When you say 1/4 do you mean the thread or the id of the outlet on the fitting?

 

Your compressor seems to have better stats, but was cheaper then mine? Mine is the pro model but why is more then yours?

Sorry I missed your responses. Let me try and respond to them all at once....

1/4" is the thread fitting size.

Your compressor is a two-stage compressor, where as mine is a single stage. The multiple stages allow for higher PSI. A two-stage is like say a V-twin engine (many 2-stage compressors are layed out in a V pattern actually) as opposed to a single cylinder. The 2-stage compresses with one cylinder first, then compresses it again to the final PSI with the second compressor. At least that's my understanding, I could be wrong. Usually they are more efficient. I think they use higher quality components with the Pro line. You can max out the PSI of the compressor to 175, but that isn't what you want to look for. The big thing is the CFM. Also the cycle. How long can you run your air tool between the compressor spinning on.

Yeah it is 1/4 thread but teh outlet on teh fitting is what I am talking about the standard i/m fitting is 1/4 id where the t fitting is 3/8 id the both have 1/4 thread. your compressor is still putting out more CFM then mine.
