York S1-029-19387-014 Orifice

The York S1-029-19387-014 Orifice is a precision-machined fixed orifice metering device specifically engineered for York, Coleman, and Luxaire evaporator coils. As a #55 refrigerant orifice, this component is critical for regulating the volumetric flow of refrigerant, ensuring the correct pressure drop occurs before entering the distributor. In the field, selecting the correct orifice size is paramount; the 014 orifice is calibrated to match specific system tonnages and SEER ratings to maintain optimal superheat and subcooling levels. This OEM York part prevents common issues such as evaporator icing or liquid slugging by providing consistent flow rates that adjustable valves might struggle to maintain in certain residential applications. Technicians should verify that the internal flow rater body is free of debris before seating the York S1-029-19387-014 to ensure a leak-free seal and accurate thermal expansion. Its durable brass construction is designed to withstand high-velocity liquid line environments without erosion.

• Precision Metering: The #55 orifice delivers an exact 0.055-inch bore for consistent refrigerant distribution.
• Direct OEM Replacement: Guaranteed fit for York S1-029-19387-014 specifications, eliminating the guesswork of universal sizing.
• Enhanced System Reliability: Minimizes compressor stress by maintaining the engineered pressure differential across the liquid line.
• High-Grade Construction: Manufactured to resist the corrosive effects of refrigerant and oil mixtures under high pressure.

Common Questions

What equipment uses the York S1-029-19387-014?
This orifice is typically found in York-manufactured residential split system evaporator coils that utilize a fixed-bore metering setup rather than a TXV.

How do I verify if a #55 orifice is correct for my system?
Check the outdoor unit’s data plate or the manufacturer’s charging chart; the required orifice size is determined by the combination of the condenser capacity and the indoor coil match.

Can this orifice be used for R-22 to R-410A conversions?
Orifice sizing is refrigerant-specific due to density and pressure differences. You must consult the specific York cross-reference guide to ensure the #55 orifice matches the BTU requirements of the new refrigerant.
