The Wacker Neuson Injection Line is a genuine OEM fuel delivery component designed for the TH627 indirect-fired air heater. As a factory-sourced part, it is manufactured to the exact specifications required by the TH627, ensuring a correct, secure connection within the fuel system. This is the same part supplied through Wacker Neuson's authorized parts network, so you can order with confidence that it will fit and function as intended.
Key Features
- OEM Fuel System Integrity — Manufactured to Wacker Neuson's exact pressure and flow tolerances for the TH627 fuel delivery circuit, maintaining consistent combustion performance.
- Direct-Fit Replacement — Engineered to connect directly to the existing fuel circuit fittings on the TH627 with no reworking of existing ports or lines.
- Confirmed Fitment — Verified for the TH627 indirect-fired air heater (418-02 parts list).
- Consistent Heat Output — A correctly functioning injection line delivers fuel to the burner at the right pressure, sustaining steady, controlled heat output. A cracked or restricted line causes inconsistent flame, reduced heating capacity, or burner lockout.
- Fuel System Safety — Injection lines carry pressurized fuel directly to the burner assembly; using a correctly rated OEM line helps prevent fuel leaks that could create a fire or carbon monoxide hazard in enclosed job environments.
The injection line carries pressurized fuel from the pump to the burner nozzle inside the heater, where it is atomized and ignited to produce the heated airflow the TH627 is designed to deliver. A properly functioning line maintains the correct fuel pressure and flow rate needed for stable, efficient combustion. When an injection line cracks, develops a leak, or becomes partially blocked, fuel delivery is disrupted — leading to inconsistent burner operation, hard starting, or complete heater shutdown.
