Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to match the original fitting's dimensional tolerances and connection specifications, ensuring a leak-free, secure interface.
- Direct Replacement for the HI 400HD G — Engineered specifically for the HI 400HD G Indirect Air Heater; installs in place of the original without modification to surrounding connections or hardware.
- Verified Fitment — Confirmed compatible with the HI 400HD G Indirect Air Heater series, so you can order with confidence.
- Maintains System Integrity — A properly seated fitting keeps fuel or fluid pathways sealed and pressurized correctly, supporting consistent heater output and preventing fluid loss.
- Fuel System Safety — Fittings in indirect air heaters are part of the fuel delivery circuit; using a correctly rated, genuine OEM part helps maintain a safe, leak-free system under operating pressure and temperature.
A fitting is a threaded or pressed connector used to join sections of tubing, hose, or pipe within a machine's fuel, hydraulic, or fluid circuit. In an indirect air heater like the HI 400HD G, fittings are critical points in the fuel delivery path — they must hold a reliable seal under the pressure and heat generated during operation. A damaged, corroded, or cross-threaded fitting can cause fuel leaks, loss of system pressure, or heater shutdown, making prompt replacement essential for safe and efficient operation.
