Vacuum Breakers

The Mepco brand Vacuum Breaker is a simple device which provides a positive means of relieving or "breaking" a vacuum at predetermined setting.

Mepco vacuum breakers are furnished with 3/8" male pipe thread and are set at the factor to begin opening at 2 inches of vacuum. They may be field adjusted from 1" to 28" of vacuum. Maximum operating pressure is 65 lb.
