eliminating the safety risks associated with "universal" adjustables that often fail to meet the delicate tolerances required for high-efficiency condensing furnaces

With a robust maximum working pressure (MWP) of 680 psig and an MOPD of 300 psig

Engineered with a 3/4" sweat connection

this unit is a reliable solution for restoring communication between the HVAC control circuit and the diagnostic interface

and the diaphragm required for most relief valve service procedures

Hydrolevel FS200 Switch 30067439-890 eliminating the safety risks associatedThe Hydrolevel FS200 Liquid Flow Switch (Part Number 44 200) is a heavy duty, general purpose control designed for high reliability flow detection in hydronic heating and cooling systems. Built to withstand a maximum pressure of 160 PSI and fluid temperatures up to 250? F, this switch is the industry standard for protecting boilers, pumps, and chillers from no flow conditions. Its universal design allows it to serve as a direct field replacement for
