Safety Air Coupler

[OctoMan]

I'm redoing my air hose and couplers. The hose is 3/8". I want to use a safety coupler due to the closed quarters of my garage. I've already had the hose ****** chip the paint on my M.G. I'm looking at Prevost. Is the internal diameter of the hose 1/4 and 3/8" the female end for the coupler?

Also which coupler should I use? Blue (Industrial), red (Truflate), yellow (AR)-220 profile), or green(High Flow) ?

I would use the green(High Flow). If you want your air tools to run properly you need high flow connectors hands down.

Also that is correct for the pipe thread dimensions.

I have all my couplers pointing down to the ground. I realized quickly of the repercussions if one should pop out and shoot across the room hitting a car or worse yet a person.

Do yourself a favor and install a 90° fitting so the quick coupler points to the ground, it will help stop it from flying across the room.

Or if you are concerned about air flow loss in a 90, at least put in a 45? A failure will still aim the force down, not straight out...

A well designed system has couplers only on the tool end of the hose, hose screwed to an outlet. Like a hose reel is set up.

Why not just hold the hose as you unplug it?

He shouldn't be unplugging under pressure. This is my point about only using couplers at the tool, very little stored energy released.

 

[Aerogt01]

Been unplugging hoses under pressure since I was... 10?

I guess you don't have much convenience on a roof.

Have you ever used a pneumatic framing nailer? There's more air stored in the handle than in 50' of most hoses.

As a side note, there are Legris connections in the shop where I work. The blue ones look really cool next to the blue compressed air piping.

I agree there are places its done all the time and did it for a long time myself, since I was 10 also but it doesn't make it a good practice and in these cases we are usually talking shop setup. A guy can afford good fittings if he needs only a couple.

I was kind of thinking about that on walk over here. It takes so much electric in comparison, can reman and paint a car easily with one air hose. The male fitting that goes on the tool is a plug, need a box of them but 1 coupler.
