Sensus 143-16-023-04 Orifice

When you're servicing large-capacity units like the Sensus 243 series, the Sensus 143-16-023-04 is the go-to 3/8" Orifice for balancing throughput and lock-up precision. This replacement orifice is engineered specifically for the Sensus 243-8 and 243-12 Gas Pressure Regulators, ensuring the flow coefficients align with your specific inlet pressure requirements. Constructed from high-grade brass or aluminum depending on application specs, this component provides the critical seat-to-valve interface necessary for maintaining stable natural gas pressure regulation in commercial and industrial settings. Using a 1-5/8" thin-wall hex socket, this orifice threads directly into the valve body to facilitate rapid field maintenance and prevent hunting or flickering in downstream boilers and furnaces. For technicians working with Sensus 243 service regulators, matching the correct orifice size is vital to prevent over-pressurization and ensure the internal relief valve (IRV) functions within its design parameters. This authentic Sensus gas regulator part maintains the tight tolerances needed for precise gas flow measurement and long-term reliability in high-demand environments.

• Compatible with Sensus 243-8 and 243-12 service regulators for seamless field replacement.
• Durable 3/8" brass orifice construction resists erosion and chemical degradation from inert gases.
• Optimized for accurate gas flow measurement, reducing pressure drop at high scfh capacities.
• Precision-threaded design allows for straightforward removal with a standard 1-5/8" hex socket.
• Supports a wide temperature range from -20°F to 150°F, ideal for varying climate exposures.

• What is the torque specification for this orifice? During installation into the 243 body, apply a moderate amount of pipe dope to the threads and secure the orifice firmly to ensure a gas-tight seal against the valve pocket.
• How do I resolve high lock-up pressure? Inspect the 3/8" orifice for nicks or debris on the seating surface. If the seat is scarred, the 143-16-023-04 must be replaced to restore proper shut-off.
• Can this be used for LPG vapor applications? Yes, this Sensus orifice is suitable for natural gas, air, propane vapor, and other non-corrosive gas services.
