The quick connect portion of the device consists of a spring loaded collar that surrounds the four metal balls and keeps them “locked” inward so that they grab onto the grove on the body connect. When the collar is lifted, the metal balls can then move out.

This ball lock disconnects for soda kegs (corny kegs) is completely new--not refurbished. It fits all ball-lock that require the standard disconnects. Mfl (threaded flare connection) allows for connection to a hose barb as well as easy removal. Durable, threaded/straight mouth design, beer keg accessories.
