The Wacker Neuson Contact Bushing is a genuine OEM component designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this part matches the original specification installed at the factory, ensuring a correct fit within the heater's electrical contact assembly. If your TH627 is showing signs of poor electrical connection or contact wear, replacing the Contact Bushing with the correct OEM part is the straightforward fix.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to the same contact material and dimensional tolerances as the original, maintaining consistent conductivity and connection quality within the heater circuit.
- Direct-Fit Replacement — Engineered to drop into the existing contact assembly on the TH627 without rework, matching the original mounting geometry and contact interface.
- TH627 Heater Compatibility — Verified fitment for the TH627 indirect-fired air heater (418-02), so you can order with confidence against your machine's parts list.
- Sustained Heater Output — A correctly seated Contact Bushing ensures stable electrical flow through the heater's ignition or control circuit, supporting consistent heat output and reliable cold-weather operation.
- Electrical Safety Compliance — Using the correct OEM contact component in a fuel-burning heater's electrical circuit is critical; substituting non-spec parts in this application risks intermittent faults or unsafe operation.
The Contact Bushing serves as a precision interface component within the electrical contact assembly of the TH627 indirect-fired air heater. It ensures that current passes cleanly and consistently between mating electrical contacts, which is essential for reliable ignition and control circuit performance in a fuel-fired heating unit. When this bushing wears or degrades, poor contact can result in ignition failures, erratic burner behavior, or complete loss of heater function — particularly problematic in cold-weather jobsite environments where continuous heat output is critical.
