They fit most circulator pumps and install directly to the circulator pump flange. The flanges feature a two-piece brass body and flange design with virgin PTFE seats and quarter-turn open or close operation, says the company. They are available in 1/2- to 2-inch sizes with threaded end connections and 1/2- to 1-inch sizes with sweat end connections. They have a maximum operating temperature of 406 degrees F (208 degrees C) at 100 psi (6.9 bars). The series comes standard with mounting nuts and bolts.
