Barnes & Jones was founded before the turn of the century by two engineers who applied their expertise to build quiet and efficient steam heating traps and systems. Today, Barnes & Jones manufactures 100% calibrated cage unit inserts, the recognized standard in the steam heating repair kit market, for every heating steam trap body ever made. Barnes & Jones products are available throughout North America, Central and South America, and most of Europe. The operating principle of these cage units, first introduced in 1902, remains unchanged as cage units emerge, today, as the preferred automatic valving solution for high-tech environmental control systems.

Barnes & Jones offers their own complete line of float and thermostatic (F&T) steam traps and radiator steam traps that are factory-calibrated. They also manufacturer repair kits for numerous brands of F&T steam traps and radiator traps, as well as, cage units for steam traps. Barnes & Jones specializes in providing repair kits and replacement parts for current and obsolete models of steam traps.
Vacuum Breakers

Barnes & Jones vacuum breakers are simple, reliable devices that provide a positive means to automatically relieve or break an unwanted vacuum condition. Their rugged hex design 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. They are suitable for steam boiler, process air heater, heat exchanger, and air/heat coil applications.
