Wacker Neuson 1000338730 Filler Pipe

The Wacker Neuson Filler Pipe is a genuine OEM component designed for the TH627 indirect-fired air heater. As a direct factory replacement, it is manufactured to the same specifications as the original part and integrates seamlessly into the fuel system of the TH627. Sourced directly from Wacker Neuson, this part carries the same quality assurance as the unit it was built to serve.

Key Features

• Genuine OEM Construction: — Produced to exact manufacturer tolerances for proper fuel channel dimensions and leak-free sealing — critical in a fuel fill application where fitment gaps are not acceptable.
• Direct Drop-In Replacement: — Matches the original mounting configuration and connection points on the TH627, allowing straightforward removal and installation without reworking surrounding components.
• TH627 Heater Compatibility: — Verified fitment for the TH627 indirect-fired air heater (418-02 spare parts list), so you can order with confidence.
• Fuel System Integrity: — A properly seated filler pipe maintains the correct fuel fill path and prevents spills, fuel odor, or air ingestion into the fuel circuit that can cause hard starts or inconsistent heater operation.
• Fuel Safety Compliance: — On indirect-fired heaters, fuel system components are safety-critical. Using a genuine OEM filler pipe ensures the fill path meets the original design intent and avoids the fire hazards associated with poorly fitting or degraded fuel system parts.

The filler pipe provides the dedicated fill pathway through which diesel fuel enters the heater's fuel tank or reservoir. It channels fuel from the fill point to the tank while keeping the surrounding components free from spillage or contamination. When the filler pipe cracks, deforms, or loses its seal, fuel can leak onto hot surfaces, introduce contaminants into the fuel supply, or allow air into the system — each of which disrupts heater ignition and sustained operation in demanding cold-weather jobsite conditions.
