Advanced Distributor Products Brass Refrigerant Metering Piston Orifice

The Advanced Distributor Products Brass Refrigerant Metering Piston Orifice is a fixed-orifice metering device (also called a piston, metering piston or refrigerant metering device) for residential HVAC air conditioning and heat pump systems. It controls how much liquid refrigerant flows into the evaporator coil, so the system can cool efficiently.

Key Features:

• Brass piston construction resists corrosion and wear
• Fixed-orifice design has no moving valve parts, which keeps it simple and dependable
• Meters refrigerant into the evaporator coil to help maintain correct system pressures and cooling performance
• Made as a replacement part by Advanced Distributor Products, a supplier of OEM-style HVAC components
• Available in multiple orifice variants. Choose the one that matches your system's requirements.

Use it to replace a worn, damaged or clogged metering piston during evaporator coil or air conditioner service. Replacing it helps restore proper refrigerant flow and system performance.
