York S1-029-26860-000 Orifice

The York S1-029-26860-000 Orifice is a precision-engineered fixed orifice metering device designed for reliable refrigerant flow regulation in residential and commercial HVAC systems. Featuring a 0.077 orifice size, this component is critical for maintaining the correct pressure drop across the evaporator coil, ensuring optimal heat transfer and system efficiency. Built with a Chatleff connection, it provides a secure, leak-resistant interface that veteran technicians rely on for fast, "drop-in" replacements during service calls or new coil installations.

For contractors managing York HVAC replacement parts, this 0.077 piston orifice is an essential stock item for balancing refrigerant velocity. Unlike complex expansion valves, this Chatleff refrigeration orifice offers a simplified, failure-resistant solution for systems requiring specific flow coefficients. Its durable construction is designed to withstand the high-pressure environment of modern refrigerant flow control applications, helping to prevent liquid slugging and maintaining precise superheat levels under standard operating conditions.

Key Benefits

• Precision Metering: The 0.077 orifice diameter ensures accurate refrigerant distribution for consistent cooling performance.
• OEM Compatibility: Genuine York S1-029-26860-000 specifications guarantee a perfect fit for compatible York, Luxaire, and Coleman equipment.
• Chatleff Fitting: Features a standard Chatleff connection for a mechanical seal that eliminates the need for additional adapters.
• System Reliability: A simplified fixed metering device design reduces the number of moving parts, enhancing long-term operational stability.

Common Questions

What is the function of the 0.077 orifice in a York system?
The 0.077 orifice acts as the primary metering device, restricting refrigerant flow to create the necessary pressure drop for evaporation and cooling.

Can I use a Chatleff orifice to replace a TXV?
While a piston orifice can be used in place of some thermostatic expansion valves, you must verify the coil’s tonnage and manufacturer specifications to ensure the flow rate matches the system requirements.

How do I identify the correct York orifice size?
The size is typically stamped on the body of the piston or listed in the unit’s technical data sheet. The S1-029-26860-000 is specifically sized at 0.077 for precise refrigerant management.
