Which of the following describes the correct release sequence for a Legris quick-disconnect fitting?

• A. Push collar, pull line
• B. Twist then pull
• C. Pull line, push collar
• D. Push line, twist

Answer: (A)

Legris quick-disconnects release by a collar-controlled locking mechanism. To disconnect safely, you first push the collar toward the body to retract the locking elements and unlock the connection. Once unlocked, you pull the hose line away to separate the two halves. This order—push the collar, then pull the line—prevents accidental disconnection and protects the fittings and hose from stress.

Twisting isn’t the release action for this style, and pulling or pushing the line without first unlocking the collar won’t separate the fitting.
