WYNNsky Coupler Connect Fittings Industrial Review

All connectors and plugs match well with each other as well as other brands, no obvious air leaks, easy connect/disconnect.

I lost my air compressor coupler and replaced it in the field thinking this kit would come in handy in a future emergency. These appear to be well made and high quality items.

Desirable purchase of additional and pneumatic tools and retractable air hose for wall mounting. So you have to be able to connect everything. With this range I can connect everything and still have a few spares in case I buy more air tools.

Good range of fittings supplied in a molded case for easy storage. If you're anything like me, you lost your hardware and had to buy duplicates. It's just a matter of finding the "lost" fittings. This set comes with a great box to keep them organized when stored.

The package looks good on arrival but the case is not very useful due to bad fasteners so it was thrown away. Some connectors and plugs were quickly used up and found sealed. I'm not sure where the metal mix is in this collection, but using a brass connector with a steel connector doesn't seem to be a problem. Satisfied.
