Sensus 019-01029-004 Orifice

Ensure reliable pressure regulation in your domestic gas service setups with the Sensus 019-01029-004. This 3/8" aluminum orifice is specifically engineered for use with the Sensus Model 496 series domestic service regulators. Designed to handle a maximum inlet pressure of 30 psig, this component is critical for maintaining precise flow control and downstream stability in residential and light commercial natural gas or propane applications. The precision-machined 3/8-inch bore allows for optimized flow capacities while working in tandem with the regulator’s 4-inch roll-out diaphragm to deliver consistent performance even at varying inlet pressures. For contractors performing field maintenance or orifice swaps, the 019-01029-004 provides an exact OEM fit to prevent lock-up issues or relief valve venting caused by improper sizing. Built from high-grade aluminum, it offers the structural integrity required for HVACR systems and industrial gas measurement environments, fitting 3/4" NPT and 1" NPT body configurations seamlessy.

• Optimized Compatibility: Specifically sized for the Sensus 496 regulator, ensuring proper lever geometry and valve seating.
• High Pressure Rating: Rated for a maximum inlet pressure of 30 psi, ideal for standard domestic service drops.
• Precision Flow Control: The 3/8" orifice diameter provides the necessary SCFH capacity for larger residential and small industrial loads.
• Durable Construction: Manufactured from corrosion-resistant aluminum to withstand standard gas contaminants and environmental factors.
• Field Interchangeable: Standardized design allows for quick removal and installation during regulator troubleshooting or capacity adjustments.

What is the maximum inlet pressure for the Sensus 3/8" orifice?
When installed in a Model 496 regulator, the 019-01029-004 orifice is rated for a maximum inlet pressure of 30 psig to maintain safe operation and lock-up performance.

Is this orifice compatible with other Sensus regulator models?
This specific part number is designed for the Sensus 496. While similar in appearance to orifices for the 143 series, technicians should always verify the specific part number in the Sensus technical literature to ensure proper thread pitch and seat alignment.

Can this orifice be used for Propane (LP) gas?
Yes, the Sensus 019-01029-004 is compatible with natural gas, air, CO2, propane, and nitrogen, provided the regulator body and spring are appropriately selected for the specific gravity of the gas.
