Question by: Keith S on Oct 9, 2025, 10:01 AM
Does this coupling need any kind of tool to hook up or disconnect, or is it pretty much hand-operated?
Answer by: Customer Support on Oct 10, 2025, 4:34 PM
No tools required at all. The ball lock mechanism lets you push to connect and pull to release without any wrenches or adapters. That makes it practical in tight spots or when you're swapping lines in a hurry on a busy job site.

Will this fitting hold up to regular use in a plant air system, or is it more for light-duty stuff?
