Why did you pick this product vs others?:Best air product on the market. Worth the extra money way better quality

I'm not sure how the aluminum will hold up but they definitely make a difference in flow. The hose is massive compared to the typical fittings you'd buy at the hardware store. The quick connect also fits my old smaller bass and steel ends so you don't have to switch everything over. They are extremely easy to take on and off. Almost too easy when it comes to taking tools off. I've done it by mistake a couple times

This Milton S-314VKIT is a fantastic upgrade for anyone needing more airflow from their pneumatic tools. The V-style fittings deliver noticeably better performance compared to standard connectors, especially with high-demand tools. Everything in the kit feels well-made and durable, and the purple color makes them easy to spot in a busy shop. Great value and performance—highly recommended for serious DIYers and professionals alike.

I just switched all my compressor and hose fittings to these high flow ones. So far so good, I will see how they hold up. The aluminum plugs weigh almost nothing compared to brass, and have very thin walls, so I'm a little worried they won't last.Also, The coupler is advertised as accepting both Industrial plugs and these high-flow ones. Industrial style plugs do fit, but there's a very slight leak. Not really a problem as you would only be doing something like that in a pinch.

works great

I bought two of these 14 packs because I wanted to convert all my tools to the hi-flo style connector. Replaced the connectors on all my tools without actually using them. I was shocked when they all leaked a large amount of air unless the connectors were perfectly aligned and zero force was applied on the connection from the hose. You can fiddle with the connection and sometimes get them to stop leaking, but as soon as you move your hose, the leaking starts again.These are awful. I really don't know how a reputable company like Milton can sell these.Update:I replaced some of the aluminum couplers I reviewed with their brass/steel equivalent "V" couplers: Milton S-217. Zero leaks with these. I did some interoperability testing between the two and it seems like the aluminum female couplers in my original purchase was the cause of the leaking. The aluminum male coupler doesn't leak at all when used with the brass female. Regardless, I'm replacing all of aluminum couplers in my shop with the brass/steel ones. It's so nice for those leaks to be gone.

Great for impact gun. Much more powerful.
