Raypak 003903F Pilot Orifice Kit – Natural Gas IID Models

If your heater struggles to light, has a weak pilot flame, or fails ignition entirely, a clogged or damaged pilot orifice is a common cause. Debris or wear can restrict gas flow and prevent proper ignition.

The pilot orifice controls the flow of gas to the pilot assembly. A clean, correctly sized orifice is critical for stable ignition. Replacing it restores proper flame characteristics and reliable startup.

  • Pilot will not light or stay lit
  • Weak or inconsistent pilot flame
  • Ignition failure or delayed startup
  • Debris or blockage in gas path

What this part does: Regulates gas flow to the pilot burner for ignition.

Compatibility: Designed for Raypak natural gas IID models.

  • Fuel Type: Natural Gas
  • Application: Pilot gas flow control
  • Type: Orifice kit

OEM Advantage: Correct sizing ensures proper ignition and safe operation. Incorrect orifices can cause ignition failure or unsafe combustion.
