York S1-001-07119-000 Shaft 318518-761 The 1-1/2" Female NPT inlet

The 1-1/2" Female NPT inlet and 2" Female NPT oversize outlet are designed to reduce backpressure and facilitate maximum discharge flow during overpressure events

The York S1-022-09092-000 Expansion Valve is a critical OEM replacement part engineered for high-performance HVAC refrigerant metering in 4 to 5-ton heat pump systems

Its polymer capacitive sensor is protected by an ePTFE filter that prevents water droplets and contaminants from reaching the sensing element

moisture in the sensing lines

making it a standard choice for Building Automation Systems (BAS) and direct digital control (DDC) applications

York S1-001-07119-000 Shaft 318518-761 The 1-1/2" Female NPT inletThe York S1 001 07119 000 Shaft is a precision engineered HVAC blower motor shaft designed for heavy duty air handling applications. Constructed from high grade carbon steel, this York replacement shaft measures 27. 75 inches in length with a precise 1. 1373 inch outer diameter (OD). This specific 1. 1373 OD tolerance ensures a critical press fit or slide fit interface with blower wheel hubs and drive assemblies, minimizing vibration and radial runout
