Stop Using Those Junk Air Tool Couplers From Harbor Freight, Couplers You Have Probably Never Seen! 

It seems that most of the content in your video is regarding the noise from coupling/decoupling air fittings where you expel the volume of air inside the hose. In my experience, 99% of the air coupling/decoupling in most shops occurs at the tool level. This is usually where the tool has a male end and the hose has a female end. The hoses are usually attached at the wall (or ceiling) and are rarely uncoupled. You aren't usually dumping the entire volume of air from the hose. I don't usually hear much more than a brief "tsssst" or "pop" so I'm baffled as to what the concern is. What am I missing? Also, in my 35 years of working with air tools, I have NEVER seen anything whip around when disconnected. Not to say it can't happen, but I just can't imagine a situation where it could possibly occur.

The “junk” couplers I got from HF seem to be holding up quite well and they duplicate the function of the Milton 5-in-1 and allow for safe (and quiet) bleeding of pressure. I know the Prevosts are good, but when you need to buy half a dozen couplers, it’s an upgrade that might not be worth it for many of us.

Perhaps a ten dollar in line back flow valve near the male end of the long shop hose will keep it from gushing air when removed from a wall connector and eliminate the need for expensive quiet female connectors around the shop walls.

Maybe more upfront cost but a manifold system with two or three hoses would be nice... Just prevent having to change tools over as often to begin with. The older I get, the less careless I get, and the more appreciation I have for what good ear and eye protection can do.

Thanks for the video. Home Depot has a Husky version of those Prevost. I've been using them with no problems for 4 years. Home Depot still sells them.

Milton V style fittings are nice. Large high flow openings collars stays open when disconnected for easy one hand connecting. Flexilla has a high flow system that looks to be similar.

Besides the difference in noise a huge difference between the Parker/prevost and the original coupler is that both prevost and Parker have dual stage release system compared to the original one that can whip around and is dangerous at times.

do manufacturers not make a captured exhaust for air fittings? They do for hydraulics.

Milton and Amflo for me

In my experience, I'm working with (apparently) lower psi pressures, so for me, it's only a safety and ease of use issue. As a result, I went with an even cheaper, all metal option: Milton S-1750 Safety Exhaust Coupler There's no way I'm airing completely down just to switch tools. Great video! More options to choose from.

Trying to sell Prevost when you proved it wasn't the best. Lol.

I've bought some decent inexpensive items at HF and as many inexpensive items of crap that go into the trash which offsets any savings from the "okay" items. I've finally eliminated the problem by not wasting my time going there and stick to the big box and local hardware store.

this is the bigest talk about nothing vid i seen in my life

Huh!!

Blue button and green stripe.. you could’ve said all this in a 30 second clip.

So they're all the same.. thanks. I'll be sure to never buy them.
