Sensus 019-01029-001 Orifice

The Sensus 019-01029-001 1/8" Orifice is a precision-machined flow control component engineered specifically for Sensus 496 and 61R2 domestic service regulators. This aluminum-alloy orifice acts as the primary metering element, establishing a calibrated 1/8-inch restriction that dictates the regulator's maximum capacity and pressure drop characteristics. Designed for high-pressure service, the 019-01029-001 is rated for an inlet pressure up to 125 PSIG, ensuring stable performance in residential and light commercial gas distribution systems. Technicians should note that this orifice is a direct replacement for Rockwell, Equimeter, and Invensys legacy 496 models, maintaining consistent lock-up and relief performance. For a proper seal, use a 7/8-inch hex socket wrench for installation and apply a high-quality thread sealant. Field specs require a torque of 50-60 ft-lbs to prevent bypass leakage. This component is cross-compatible with the Sensus 043-B series, providing the necessary variable restriction for accurate utility metering and downstream safety.

• Precise Flow Control: Calibrated 1/8" aperture ensures accurate gas metering and consistent outlet pressure.
• Industrial-Grade Pressure Rating: Safely handles inlet pressures up to 125 PSIG for versatile field applications.
• OEM Compatibility: Exact replacement for Sensus 496, 61R2, and older 043-B regulator models.
• Durable Construction: Corrosion-resistant materials withstand heavy-duty service in natural gas and propane environments.
• Standard Fitting: High-tolerance 7/8" hex interface allows for straightforward removal and installation during regular maintenance.

Is this orifice compatible with propane (LP)?
Yes, the Sensus 019-01029-001 is designed for use with non-corrosive gases, including Natural Gas, Propane (LP), and Air.

What is the correct torque for installing this Sensus orifice?
To ensure a gas-tight seal and prevent damage to the valve body, the orifice must be torqued to 50-60 ft-lbs.

Can I use this 1/8" orifice to replace a larger 1/2" orifice?
While the threads may match, changing orifice sizes will significantly alter the regulator's flow capacity and performance curve. Always consult the Sensus 496 capacity charts before downsizing.
