Sensus 143-16-023-03 Orifice

The Sensus 143-16-023-03 Orifice is a precision-engineered 1 1/4" gas regulator orifice designed specifically for the Sensus 243 service regulator series. Built to industrial standards, this replacement component facilitates critical flow control for high-capacity applications including commercial boilers, large-scale furnaces, and district regulator stations. When installed in 2" NPT or flanged bodies, this orifice size supports a maximum inlet pressure of 30 psi, ensuring stable regulation for natural gas, LPG, and other non-corrosive vapors. For high-volume demand scenarios such as industrial combustion systems, the 1 1/4" orifice for 243 provides the necessary port size to maintain setpoint accuracy and minimize droop. Field technicians should utilize a 1-5/8" hex thin-wall socket for installation and apply a moderate amount of high-quality pipe dope to the threads to maintain a pressure-tight seal. This genuine OEM part ensures the manifold pressure remains consistent across varying load changes, protecting downstream equipment from overpressurization.

• Maximum Flow Capacity: Large 1 1/4" port designed for high-volume commercial and industrial gas loads.
• OEM Compatibility: Exact fit for Sensus 243 regulators, including RPC and IRV internal relief models.
• Durable Construction: Highly resistant to wear and localized erosion within high-velocity gas streams.
• Wide Medium Range: Suitable for natural gas, propane, air, nitrogen, and dry CO2.
• Inlet Pressure Rating: Optimized for systems with a maximum inlet pressure of 30 psig.

What tool is required for the Sensus 143-16-023-03 orifice installation?
Technicians must use a 1-5/8" hex thin-wall socket to avoid damaging the orifice or regulator body during replacement.

Is this part compatible with the Sensus 143 series regulators?
No, this specific part number is engineered only for the larger Model 243 regulator series. For the 143 series, different orifice dimensions are required.

What is the maximum inlet pressure when using this 1 1/4" orifice?
When utilizing the 1 1/4" orifice size in a Model 243 regulator, the maximum allowable inlet pressure is 30 psi for optimal performance.
