Advanced Distributor Products 176799953 Piston THPU32HP7Y or erratic "hunting" pressures whereThe ADP 176799953 is a precision engineered #53 ton piston designed for reliable refrigerant metering in residential HVAC systems. Also known as a fixed orifice metering device, this genuine ADP replacement part is critical for maintaining the correct pressure drop between the high and low sides of the cooling circuit. Specifically sized for 1. 5 ton R22 or 2 ton R410A evaporator coils, it ensures the optimal flow of refrigerant to maximize heat
