Description
The Sensus-Gas Division 143-62-023-43 Orifice 143 is a flow-regulating insert used to meter gas passage within regulator and valve assemblies. It operates through a precision 5/16-inch opening that restricts gas flow, maintaining consistent delivery as pressure moves through the internal channel. In gas-fired equipment used in HVAC setups, it is commonly integrated in combustion and control circuits to balance fuel distribution toward burner sections. Fitted inside the regulator body, it aligns with internal pathways to guide measured gas movement, enabling steady combustion conditions and controlled energy input during system operation.
