Raypak 004078F – Pilot Tubing – IID Heater Replacement
If the pilot flame is weak, inconsistent, or not receiving gas even though the rest of the pilot assembly looks intact, the pilot tubing is worth checking early. A kinked, cracked, or restricted line can starve the pilot and turn a simple tubing issue into repeated ignition failure.
This pilot tubing carries gas from the valve to the pilot assembly on compatible IID heaters. When the line is damaged, blocked, or no longer sealing correctly at the ends, pilot gas flow suffers and the heater may fail to light or stay lit. Replacing it restores the gas path feeding the pilot flame.
- Pilot is weak or will not establish a stable flame
- Pilot gas line is kinked, cracked, or leaking
- Ignition sequence fails because pilot gas is not reaching the assembly correctly
- Need to fix a Raypak heater with pilot-side gas delivery issues
What this part does: It carries gas from the valve to the pilot assembly for proper pilot ignition.
Compatibility: Used on select Raypak IID heaters. Confirm with your model number before ordering.
- Part Number: 004078F
- Type: Pilot tubing
- Application: IID heater replacement
OEM Value: A genuine Raypak pilot tube helps maintain the intended routing and connection fit at both ends of the pilot circuit. Small fuel-delivery parts matter because restricted pilot flow can create larger ignition complaints fast.
