air tool couplers

Sep 20, 2007 3 Replies

What coupler type do you recommend for air tools used for automotive work - eg impact wrench?



There are many choices, but two popular ones are industrial interchange and "automotive". The industrial interchange one seems more common, but the automotive style appears to have a higher flow rate. Is this difference significant?



Thanks

Are you just asking about the quick connect coupler?? If you look at the CH line for example, they often have coloured bands on them indicating which connector they will mate with. If you get the one that's got red/blue/yellow banding, it will connect with virtually all of them. That being said, I would suggest that you use a 'whip hose' with a swivel on it to avoid tangling yourself up, damaging tools, etc. The rule is generally that if you have a 5/8 line, you use a 5/8 connector... 1/2 line... 1/2 connector... And so on... I have used everything from garden-variety bargin bin right to industrial line and CH and have almost never has any issues. Unless I am completely misunderstanding your question, my advice is to ensure that the tools get lubrication, you remove the water, and use a whip.

HTH Andrew.

I get the page and it hangs.

Yes, the flow rate is significant.

I changed the stock line that came on my compressor with one that was

1/8" larger internally and the difference was extreme. That was a 33% increase in size though.

Oops, that was supposed to have been snipped from another post and got dropped here by a errant mouse click.
