Legacy MTA53452FZ High Flow Coupler & Plug Kit 3-Piece 1/4" Npt Flexzilla, Price/EA

Good quality for my shop

A-Plus. Check out the opening on you fittings! You may find that the cheap Harbor freight ones have a much smaller hole and you aren't getting as much flow to your air tools.

The Flexzilla Pro High Flow Coupler amp; Plug Kit (A53452FZ) is a solid upgrade for anyone using air tools or compressors. I swapped out my old standard fittings for this high-flow kit, and the difference was immediatebetter airflow and more consistent tool performance. The 1/4" NPT fittings are well-machined and leak-free, ensuring a secure connection. The brass and aluminum construction feels durable and lightweight, and the coupler’s push-to-connect design makes it quick and easy to attach and disconnect tools. These high-flow fittings increase air volume by up to 70, which means better performance for impact wrenches, spray guns, and other pneumatic tools. If you’re still using standard couplers, this upgrade is worth it. One small thing to note: Since these are high-flow fittings, they aren’t compatible with standard couplersyou’ll need to switch over all connections to match. And here’s a quick joke: Why did the air coupler get promoted? Because it always knew how to make a solid connection! Overall, the Flexzilla Pro High Flow Coupler amp; Plug Kit is a well-built, high-performance upgrade for air tools and compressors. It’s durable, easy to use, and improves airflow, making it a great investment for DIYers and professionals alike.

Seems durable enough as long as your not tossing your air tool on the ground. It offers a lot of flexibility. The connection is solid with Teflon tape. It's medium duty I would say and lightweight for what it is. It serves it purpose as intended. Was easy to install.
