The Wacker Neuson Injection Nozzle is a genuine OEM component designed for the TH627 indirect-fired air heater. As a direct factory replacement, this nozzle is sourced and supplied to the exact specification used in original production, ensuring proper fuel atomization and combustion performance. It is confirmed to fit the TH627 (418-02) heater series, making it a straightforward service replacement for technicians and operators maintaining this equipment.
Key Features
- Genuine OEM Fuel Atomization Spec — Manufactured to the exact orifice and spray-pattern specification of the original, ensuring correct fuel atomization for efficient combustion in the TH627 heater.
- Drop-In Service Replacement — Designed to seat and seal in the original nozzle port without adaptation, streamlining service turnaround on the TH627.
- Confirmed TH627 Fitment — Verified for the TH627 (418-02) indirect-fired air heater series using Wacker Neuson parts list 418-02.
- Consistent Heat Output — A properly functioning injection nozzle delivers the correct fuel charge to the combustion chamber, maintaining rated heat output and stable operation during cold-weather work.
- Fuel System Safety — A worn or partially blocked injection nozzle can cause incomplete combustion, fuel buildup, or erratic burner behavior; replacing with a genuine OEM part restores safe, controlled operation.
The injection nozzle is responsible for delivering a precisely metered, finely atomized spray of diesel fuel into the combustion chamber of the heater. Correct atomization is essential — if the nozzle is clogged, worn, or damaged, fuel may not combust fully, leading to reduced heat output, sooting, rough burner cycling, or ignition failure. Replacing a faulty nozzle with a genuine OEM part like the 1000338603 restores the correct spray pattern and fuel delivery rate, returning the TH627 heater to its full, rated performance.
