Product Questions & Answers

How does this thing keep from gettin' snagged on stuff and disconnected by accident?
Question by: Janet E on Jan 30, 2026, 4:53 PM
A protective collar helps prevent accidental snagging and unintentional disconnection. Plus, it's got a pin latching mechanism for extra security.

does this thing vent off the air pressure before it fully disconnects, or do you just get a blast of air when you pull it apart?
Question by: Lee E on Aug 30, 2025, 8:18 PM
Safe automatic venting of trapped air happens during the disconnect process, so you're not getting a sudden pressure release all at once. The swing coupling design lets you retract the release sleeve and swing the assembly to an angled position, which bleeds off the pressure in a controlled way before the halves fully separate. That's one of the main reasons this series gets used in air tool applications where you'd rather not have pressurized air kicking back at you every time you break a connection.
