Advice please -Air Compressor -Euro Coupler or PCL fittings?

I should also have said, keep an eye on the condition of any rubber hoses - I've had a couple burst and it's like a rifle shot going off......as well as the pipe trying hard to whip you!

Occasionally I'll squirt some thin oil into the air connection at the tool itself - or maybe use the oil hole with a trigger oil can. The tool will shoot most of the lube out anyway.
This is a big no-no if paint spraying, of course!

I tend to just put 4 to 5 drips of air tool lubricant down the whip hose (end of the tool) at the start of any session. That's it. Like John I found in-line oilers to be generous when it comes to certain jobs - if you deliver a nailed sub-floor generously lubricated wirh oil the floor layers tend no to like it that much (because their SLC won't always stick to it). Whilst I normally use air tool oil, any light mineral oil such as sewing machine oil does just as well, however compressor oil tends to be a lot heavier (something like 20W or 30W engine oil) and can gum up some tools - allegedly. It is always worth keeping separate hoses for spraying and other work - spraying requires contaminant-free hoses, but the air also needs to go through both a coalescing water filter, and then a 5 or 10 micron carbon filter to get nice clean air. It can be worth having colour coded air lines -
maybe blue for oiled tools, red for clean air? Ordinary tools are also best fed through a coalescing filter (alone) - this takes water out - but if tools are being put away for long periods it is best to strip the tools and clean out any residual oil/water mixture inside the cylinders/motors (you get this a lot with nailers even when they are fed through a coalescing filter).
