5 in ONE™ Universal Safety Exhaust Quick-Connect Industrial Coupler 1/4" Male NPT, Accepts All Major Interchanges, Safely Disconnect and Eliminate Potentially Dangerous Hose Whip

Excellent quality air coupler with all of the functions that make these units easy and safe to use. So far no leaks and easy to connect.

Working in an Autobody shop my entire career. I have pretty much used every kind of air fitting out there. I got a few of these for my home shop. The build quality is amazing. They work on every style air fitting, but high volume fittings. They are a little bulky in diameter. But the connection is solid. And the sliding air shut off is great. For any older tools that leak a little air. If you are working with various air tools and have different air fittings. It’s great that you don’t have to change them out. Especially nice if you take your work tools home for a project. And your work fittings, are different then your home tool fittings.

There are great devices and are very easy to connect/disconnect. The locking collar stays in position to accept the next connector when it releases a connector. The male connector inserts very easily. These are really a joy to use. There is no more struggle to pull the collar into position while trying to jam the male connector into it. One caveat: the slider to relieve pressure in the line before disconnecting a tool must be returned to its closed position before the connector will allow air to flow through it. The slider must be moved down to relieve pressure in the line before disconnecting a tool. Once the tool is disconnected, the slider must be moved up to its closed position or it won't allow air to flow when the next tool is connected. The pressure release feature is a very good thing and is very, very simple and easy to operate. It is no hassle at all. The fact that this item works with 5 different types of male connectors is beyond useful. It eliminates the need to change out the male connectors on tools because it is not compatible with the female connector on the air supply hose. Even if your connectors are all compatible, that may not be the case with a new or used air tool you acquire. Or perhaps a friend is working in your shop with his/her own air tools. With these connectors, it won't matter what male connectors he has on tools.

Awesome fitting with built in safety thought of for users.

I love this quick connect coupler. It did take me a little bit to figure out where to place it in my system. At first I tried using it on the end of the hose the nail gun was attached to. That didn't work for me because it was too easy to slide the coupler and cut off the air. Works great attached to my compressor where the hose attached. Takes multiple styles of connectors, big plus if I'm borrowing stuff or someone brings their own equipment. Better yet it will bleed off the air pressure so it's easy to disconnect or attach hoses or tools. I use a different multi connector for the end of the hose, so I don't cut my air off as I grab or drag it around. Great value.

LOVE IT. Great quality and definitely worth replacing the OEM part with this. Works better than the original part.

The best there is, just wish they would last longer. If there is the slightest imperfection on the inlet nipple, the gasket leaks and continues to leak forever. However, when they last, they are fantastic! I love being able to shut off the the air supply.

These are great!! My hands are not working like they used to and it was getting harder and painful to disconnect. These are super easy and no air leaking!

Me encantó, es súper práctico y de buena calidad lo recomiendo

Easy to use

Great product, Ive only used with high flow fittings but fits them all

Awesome adaptor. I Bought 2 try out, and will be ordering a few more today for my other hose reels here in my shop. 👍

Love it no more changing connectors
