Robertshaw 10-114 Pilot Orifice

The Robertshaw 10-114 Pilot Orifice is a precision-engineered LP gas orifice designed for reliability in commercial and residential HVAC/R heating systems. Featuring a 0.010-inch orifice diameter, this component ensures a stabilized fuel-to-air ratio, maintaining a consistent pilot flame essential for reliable ignition cycles. This part is a direct replacement and is verified as identical to the 62-19640-03 Rheem/Ruud specification, offering seamless integration into existing burner assemblies. Constructed from high-grade brass to resist thermal degradation, it facilitates optimal gas flow control for liquid propane pilot assemblies. When troubleshooting intermittent pilot issues or flame lifting, replacing a clogged or corroded orifice with a fresh Robertshaw pilot burner orifice is a standard field procedure to ensure system uptime. Proper installation requires precise alignment within the pilot burner bracket to prevent carbon buildup and nuisance lockouts in high-demand environments.

• Universal Compatibility: Interchanges directly with Rheem 62-19640-03, reducing the need for multiple SKUs on the service truck.
• Precision Metering: The 0.010 orifice size provides exact LP gas flow for stable pilot operation.
• Durable Construction: Heavy-duty brass machining ensures longevity under high-heat conditions in the combustion chamber.
• Simplified Maintenance: Direct-fit design allows for rapid field replacement during routine furnace tune-ups.

Is the Robertshaw 10-114 compatible with natural gas systems?
No, this specific orifice is calibrated with a 0.010 opening specifically for liquid propane (LP) pilot applications. Using it with natural gas will result in an inadequate pilot flame.

Can I use this orifice to replace a 62-10640-03 part?
Yes, the Robertshaw 10-114 is functionally identical and acts as a direct replacement for the 62-19640-03 burner orifice found in many OEM configurations.

What causes these orifices to fail most frequently?
Most pilot failures stem from soot accumulation or internal blockages. Because the 0.010-inch diameter is extremely small, even minor debris can disrupt the gas flow, necessitating a replacement rather than an attempt to clean the bore.
