Lennox 24X43 Distributor Piston Size 55 HVAC Refrigerant Metering Device

The Lennox 24X43 is a precision-engineered distributor piston designed for use in compatible Lennox HVAC systems. This genuine OEM replacement part features a size 55 orifice specification, making it a critical component for maintaining proper refrigerant distribution and system efficiency.

Key Features:

• Size 55 orifice piston for precise refrigerant flow control
• Genuine Lennox OEM part number 24X43 (also known as 100579-107)
• Ensures equal refrigerant distribution across multiple evaporator circuits
• Helps maintain optimal two-phase refrigerant flow for efficient heat transfer
• Replaceable design allows for easy maintenance and system optimization
• Constructed from durable brass materials for long-lasting performance

Distributor pistons play a vital role in HVAC system performance by regulating refrigerant flow through a fixed orifice. The size 55 designation refers to the specific bore diameter, which controls the volume of refrigerant passing through the system. This precision metering helps prevent issues such as refrigerant flooding, uneven cooling, and reduced system efficiency. Proper piston sizing is essential for matching your system's capacity requirements and ensuring optimal energy efficiency.

This component is designed to work with Lennox multi-circuit evaporator systems, where it helps create the necessary pressure drop to maintain proper refrigerant velocity and achieve balanced distribution across all circuits.
