York Pilot Orifice

Overview

The Source1 2920422056 is a pilot orifice designed for use in gas heating systems that rely on a standing pilot or intermittent pilot ignition assembly. This orifice is a size 56 with a bore diameter of 0.0465 inches, making it a precision-machined component that controls the flow of gas to the pilot burner. Proper gas flow at the pilot is critical for reliable ignition and stable flame operation. When a pilot orifice is worn, clogged, or incorrectly sized, the pilot flame can be too weak to hold the thermocouple or thermopile at temperature, causing the main gas valve to shut off and leaving the system without heat. Replacing the orifice with the correct size restores the proper fuel-to-air mixture at the pilot assembly. This part is commonly used by HVAC technicians during furnace repairs, pilot assembly rebuilds, and gas valve troubleshooting. It is a direct replacement component sourced from Source1, the genuine parts and supply brand associated with York heating and cooling equipment. HVAC service professionals working on York furnaces, air handlers, and other gas-fired appliances will find this orifice a straightforward, code-compliant replacement. The part measures 1.2 inches in length and 0.45 inches in both width and height, with a weight of approximately 0.595 pounds. Its compact size makes it easy to carry in a service van parts inventory. Stocking the correct pilot orifice sizes reduces return trips and helps techs close out service calls on the first visit.…
