The MEPCO Vacuum Breaker provides a positive means of relieving or “breaking” a vacuum at a predetermined setting. It is designed to prevent such damage to freezing coils, jacket collapse, or water hammer.

MEPCO Vacuum Breakers are furnished with a 3/8″ male pipe thread and are set at the factory to begin opening at 2″ of vacuum.

The vacuum breaker opening point is readily adjustable to match installation requirements.

MEPCO also offers a line of “pre-set” vacuum breakers. These models are available in four NPT pipe sizes: 1/8″, 1/4″, 1/2″ and 3/4″.
