Vacuum breakers

We provide vacuum breakers that feature a rugged hex design that ensures long life and easy installation. These breakers provide a bubble tight seal thanks to spring pressure against the valve and the o-ring which is made from soft silicon.

Some of the many applications our vaccum breakers are used for include space heaters, process air heaters, shell and tube heat exchangers, make-up air coils, textile dry cans, steam boilers, storage heaters, jacketed kettles, and more.

Our various models all feature brass bodies, stainless steel springs, brass or silicon seats, and stainless steel or brass and silicon valves. They are rated for use with maximum pressures of 125 psig (8.6 Bar), and temperatures up to 350 F.
