Coilhose Pneumatics solves the problem of “where the heck did I put my blow gun?” with their CoBlo air line coupler, which has a built-in blow gun.
The CoBlo is a female air line coupler that you attach to the end of your air hose. It is meant to be a higher quality coupler, and uses 6 balls to hold onto the male coupler rather than just 4 balls like some cheaper couplers.
The CoBlo has a maximum working pressure of 120 psi. (Note: if the airline pressure exceeds 30 PSI, as a blower the CoBlo might not meet OSHA regulations.)

To activate the blow gun, just press the push button trigger on the side of the coupler.
It doesn’t matter if an air tool is connected to the coupler or not, the blow gun can be used as long as the airflow isn’t blocked by the tool. But, you’ll probably want to disconnect the tool first, for ease of use.
The CoBlo is available in the following coupler styles:
- 1/4″ Female NPT Megaflow (11CBG4F)
- 1/4″ Female NPT ARO (14CBG4F)
- 1/4″ Female NPT Industrial (15CBG4F)
- 1/4″ Female NPT Automotive (16CBG4F)
If you need a refresher on air line couplers, see my post explaining the different types. Megaflow seems to be a proprietary coupling style exclusive to Coilhose Pneumatics, it seems very similar to the Milton high flow V-Style couplers.
The CoBlo coupler blow guns aren’t cheap, they run somewhere between $11 and $15 on Amazon depending on which coupler style you need.

Since there is no by-pass port, I wonder if this would meet OSHA regulations even below 30psi.
Bill
That was my first thought, unless there is some form of hidden bypass we can’t see.

Given where the orifice is located, it looks like it would be pretty tricky to mash it directly against your body anyway. Whether or not that pleases your local OSHA inspector, who knows, but in practice it doesn’t look too bad.
If I hadn’t already put inline blowguns on most of my hoses, I’d be picking up a few of these for home.
fred
I was kind of thinking the opposite – in that you might grip the coupler with a finger over the blow-jet orifice and inadvertently push the button – or I’d bet that one of the OSHA inspectors I dealt with would see it that way

As mentioned in the post, we believe that the air line would have to be manually regulated to under 30 PSI to meet OSHA safety regulations. None of the sales flyers or documentation by Coilhose Pneumatics mention this at all.
Coilhose Pneumatics says the following on a separate page:
Models that are designated as “safety” conform to OSHA standards for noise levels (1910.95) and 30 psi dead-end pressure (1910.242B).
Since this one isn’t designated as a safety blow gun, and there’s no mention of regulation, it would be fair to assume that it doesn’t conform to OSHA standards for dead-end pressure, at least at the >30 PSI pressures most users will be operating their tools at.

I see both sides to the equation but since I don’t have one in my hand – I can see how you might not be able to seal off that recess – and the air would move regardless.
hard to say without holding one. Neat idea though I could see using that with my nail guns. But my bostitch gun has a blower feature

I’ll stick with my Milton V series connectors. They’re really high flow and do not leak at all. What more could you want?

A blower?

There is nothing more frustrating that having something not work on your air line because of all the stupid styles. I only buy universal female ends now, and it doesn’t look like they make one unfortunately

This is ideal for collision repair or woodworking when you are using an air tool and you are so lazy that you just don’t want to uncouple the tool (like me) to blow away the dust!
Bill
If the tool needs to be removed to use, why not take a second to put on an actual blow gun.?
PETE
The tool does not nee to be removed to blow. On the opposite side of the button is where the air come from. And at that it is angled at a 30 degree angle so it blows forward of the fitting.
I have two of these and they’re OK for a quick light burst of air to move some dust. But if you need some HEAVY air pressure grab a real nozzle.

My Bostitch Smart Point finish nailer has an integrated air blower. It uses a button on the side. It seemed pretty slick to me.
Yadda
Neat! Definitely something to add to my list of desirables.
PETE
I have two of these…. This is one of those tools that you think you need/want but then you get it and…. turns out you didn’t need it lol. This is a fitting that you don’t want to lay on the ground that it might get stepped on
