Sensus 019-01029-002 Orifice

The Sensus 019-01029-002 is a precision-engineered 3/16" replacement orifice designed specifically for the Model 496 domestic service regulator. As a veteran-grade HVACR component, this orifice provides critical flow control for natural gas, propane, air, and other non-corrosive gases in residential and light commercial meter sets. For technicians performing field service or rebuilds, this part is essential for maintaining the 496’s lock-up performance and ensuring the 4-inch roll-out diaphragm operates at peak efficiency. When replacing the orifice, ensure the seating surface is free of debris and pipe dope. Apply a compatible thread sealant to the male threads and torque to the manufacturer-specified 50-60 ft-lbs using a 7/8" hex socket to prevent bypass leaks. Swapping to this 3/16 inch gas regulator orifice allows for specific BTU capacity adjustments, optimizing the regulator for variable inlet pressures up to 125 psig while maintaining stable outlet pressure under shifting load demands. This genuine Sensus part ensures full compatibility with the Model 496-20 and 496-10 valve bodies without the risk of seat misalignment found in generic alternatives.

• Specifically engineered for Sensus 496 regulator compatibility to ensure exact flow rates.
• Durable high-grade material construction resists wear from high-velocity gas and particulates.
• Supports precise gas flow control for residential, small industrial, and commercial burners.
• Maintains internal relief valve accuracy by providing a consistent port diameter.
• Direct-fit HVACR replacement part simplifies field maintenance and reduces downtime.

What is the proper torque spec for installing this orifice?
For a secure seal on the 019-01029-002, use a 7/8" hex socket and tighten to 50-60 ft-lbs. Over-torquing can damage the valve body, while under-torquing leads to internal leaks.

Is this orifice compatible with the Sensus 043-B?
Yes, since the Model 496 is the direct successor to the Sensus 043-B, these orifices are interchangeable across those specific legacy domestic regulator platforms.

Does this orifice work with propane?
Absolutely. While flow capacities are rated for 0.60 specific gravity natural gas, this component is certified for use with propane, butane, air, and nitrogen when corrected for specific gravity.
