Review: Bulky, but a great quality air fitting. - 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.
Review: Terrific piece but a little pricey. - 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.
