Bard 5603-009 - Natural Gas Pilot Orifice BCR18

Bard 5603-009 is an OEM natural gas pilot orifice stamped BCR18 used in Bard gas heat sections to meter pilot gas flow for consistent ignition and a stable pilot flame. A correctly sized pilot orifice is critical for proper flame sensing and reliable light-off, especially if your pilot flame is weak, lifting, or yellow due to wear, debris, or an incorrect prior replacement. Use this Bard factory part to maintain the designed pilot burner gas rate and dependable burner operation, and confirm BCR18 and natural gas application match your unit model and fuel before ordering.
