Sensus 143-62-023-44 Orifice

The Sensus 143-62-023-44 is a precision-machined 3/8 inch aluminum orifice engineered specifically for the Sensus 143-80 series domestic service regulators. Designed for high-performance gas pressure regulation, this OEM Sensus orifice ensures accurate flow delivery and consistent lock-up characteristics across a variety of media, including natural gas, LP vapor, and air. In the field, technicians value the 143-62-023-44 for its robust aluminum construction, which resists corrosion and provides a reliable seat-to-orifice seal, critical for preventing over-pressurization in residential and light commercial meter sets. This component is a direct replacement part, maintaining the original manufacturer’s specifications for maximum inlet pressure and capacity ratings. Proper installation requires a 1-inch thin-wall hex socket and 50-60 ft-lbs of torque to ensure a leak-free fit within the cast iron regulator body. Whether you are performing routine maintenance or converting a Sensus 143 regulator for different load requirements, this 3/8" orifice provides the flow stability necessary for modern high-efficiency appliances.

• Precise Flow Regulation: The 3/8" bore is optimized for specific natural gas regulator capacities, ensuring stable downstream pressure.
• OEM Compatibility: Guaranteed fit for all Sensus 143 series models, including the 143-80-1, 143-80-2 (IRV), and 143-80-6 (LPCO).
• Durable Aluminum Construction: Lightweight yet rugged material designed to withstand maximum inlet pressures up to 40 psig or higher in specific configurations.
• Ease of Service: Engineered for quick field replacement using standard HVAC technician tools, minimizing system downtime.

Is this orifice compatible with other regulator brands?
No, this is a proprietary Sensus 143-62-023-44 component designed exclusively for Sensus (formerly Rockwell, Equimeter, or Invensys) 143 series regulators.

Does this part include the valve seat?
This listing is for the 3/8" aluminum orifice only. It is recommended to inspect the Buna-N valve pad for wear when replacing the orifice to ensure a positive dead-end lockup.

What is the torque specification for installation?
To maintain a proper seal and avoid damaging the internal threads of the gas pressure regulator, the orifice should be torqued to 50-60 ft-lbs.
