Boiler Orifice Unions

3/4 inch NPT Boiler Orifice Union.

Plates restrict the water flow across the boiler probe to minimize the amount of steam flashing across the boiler probe. By restricting the water flow, the boiler probe may accurately read the water conductivity during blow down.

Purchase the Boiler orifice plates separate. Boiler Orifice Plates may be purchased with 1/16 inch, 1/8 inch, and 1/4 inch center holes.
