Robertshaw 10-028 Orifice

The Robertshaw 10-028 is a precision-engineered LP gas orifice designed for specific pilot burner applications requiring a .008 drill size. This component features 1/4" x 3/16" dimensions, ensuring a secure and leak-free fit within compatible pilot assemblies. For service technicians, utilizing the correct Robertshaw pilot orifice is critical for maintaining proper flame stability and preventing nuisance pilot outage issues in liquid propane systems. This industrial gas orifice is built to withstand high-temperature environments, providing consistent fuel flow and optimal combustion efficiency. When diagnosing furnace pilot light problems or water heater pilot issues, replacing a clogged or damaged orifice with this OEM-spec part ensures the system operates within its original design parameters. Ensuring the gas burner orifice size matches the appliance requirements is essential for safety and reliability in the field, making the 10-028 a vital stock item for technical gas service kits.

Key Benefits

• Precision Flow Control: The .008 orifice diameter provides an exact fuel-to-air ratio for stable LP pilot flames.
• Durable Construction: High-grade brass body resists thermal degradation and corrosion in demanding combustion chambers.
• Standardized Fit: The 1/4 inch by 3/16 inch sizing facilitates quick installation across various HVAC pilot burners.
• OEM Reliability: Direct replacement part ensures compatibility and reduces labor time during gas appliance repair.

Common Questions

How do I determine if my system uses an LP or Natural Gas orifice?
The Robertshaw 10-028 is specifically calibrated for LP gas applications. Using an LP orifice with Natural Gas will result in an insufficient flame, while using a Natural Gas orifice with LP can cause dangerous over-firing.

What are the symptoms of a clogged Robertshaw 10-028?
Common indicators include a weak, yellow pilot flame, difficulty lighting the main burner, or the thermocouple failing to drop out due to insufficient heat from the pilot.

Can this orifice be cleaned if it becomes obstructed?
While some techs use compressed air, it is standard practice to replace the pilot orifice entirely. Using a needle or wire can enlarge the drill size, compromising safety and system calibration.
