Fixed Orifice Piston For Air Conditioners and Heat Pumps

An orifice / piston is a device with a small hole which allows gas or liquids to flow through at a slow rate. In furnaces, orifices are usually used for regulating pilot and main gas flow. In air conditioning units, orifices regulate the flow of freon.

The flow rater (piston) is installed in the evaporator coil when the coil is a different tonnage rating than the condenser tonnage rating. Installation is easy and will ensure your system functions optimally.
