Milton’s V-Style high flow couplers and plugs are ideal for high volume, low-pressure applications. These couplers will also accept M-Style and A-Style plugs. However, V-Style plugs are recommended to retain maximum airflow. With their push-type sleeve release, simply push the plug into the coupler to engage and pull the sleeve release back to remove. Maximum inlet working pressure of 300 PSI. 1/4" basic flow size. Airflow of up to 74 SCFM.
