State if the following is True or False? After fixing the snap on hydraulic couplings of portable Framo, secure it with locking ring—only then the arrangement is safe.

Answer & Explanation

The correct answer is Option A: True.

For portable hydraulic pumps, the snap-on couplings are high-pressure connections. Securing the locking ring is mandatory to prevent accidental disconnection due to vibration or pressure surges, which could cause high-pressure hydraulic oil spray and pump failure.
