Performance and durability

This set is designed for air shop or garage use and supports pneumatic tasks that require more than 60 SCFM, with a maximum airflow of 99 SCFM and a 300 PSI maximum working pressure. It tolerates temperatures up to 250°F, making it suitable for a range of tools and environments. Inside the coupler are six locking balls that grip the plug securely, while sleeve guards help minimize accidental disconnects. The combination of heat-treated steel and zinc plating provides resistance to corrosion and long‑lasting performance in active shop settings.

Installation and compatibility

The 1/2 I/M Industrial coupler can connect with I/M Industrial and Automotive type plugs sharing the same body size, and it works with fittings from other brands when a seal tap is used during connection. This flexibility supports quick transitions between tools and setups in a dynamic workspace.
