Barnes & Jones Vacuum Breakers are simple, reliable devices that provide a positive means to automatically relieve or "break" an unwanted vacuum condition. The rugged hex design, machined from solid brass, provides for long service life and ease of installation. Bubble-tight sealing is assured due to the soft silicon O-ring and spring pressure against the valve.
