Boiler Orifice Unions

What is a Boiler Orifice Union?
Boiler Orifice Unions are designed to hold boiler orifice plates. The orifice 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. This will allow the boiler controller to function properly. They come in 1/2" and 3/4" diameters.

You must also purchase the plates separately.
