The Robertshaw 10-114 is a precision-machined LP/propane pilot orifice with a 0.010" bore, designed to slip into 3/16" or 1/4" pilot inlet tubing. Its job is to meter the exact amount of propane that flows into the pilot burner head, producing the small, stable flame that holds the thermocouple hot and proves to the gas valve that it's safe to release main-burner gas.

LP and natural-gas pilots use different orifice sizes because LP has roughly 2.5x the heating value per cubic foot of natural gas. Run a natural-gas orifice on propane and the pilot soots up and starves the thermocouple. The 0.010" 10-114 is calibrated specifically for LP service in Robertshaw 2C / 2CH-style pilots.

Common failures: orifice plugged with spider web, hard-water condensate, or rust scale from the supply line (no pilot light at all); wrong-size orifice installed during prior service (weak yellow pilot, won't hold the thermocouple); orifice missing entirely after gas-valve replacement. A fresh OEM 0.010" 10-114 restores a tight blue pilot flame and reliable thermocouple millivolt output.
