The Wacker Neuson Suction Pipe is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45 direct fired radiant heaters. As a factory-sourced part, the is manufactured to the exact dimensions and material specifications required for correct installation and a proper fuel-system seal. Sourcing the correct OEM suction pipe ensures the heater's fuel delivery circuit operates as intended, supporting consistent burner performance in demanding jobsite conditions. Confirm your model number before ordering to ensure a direct-fit replacement.
Key Features
- OEM Fuel-System Integrity — Manufactured by Wacker Neuson to exact material and dimensional tolerances, ensuring a leak-free connection within the heater's fuel supply circuit.
- Direct-Fit Installation — Engineered to match the original mounting points and inlet/outlet geometry of the HDR series fuel system, dropping in without rework or modification.
- Confirmed HDR Series Fitment — Compatible with the HDR 155 Direct Fired Radiant Heater and the HDR 45, covering both models in the direct fired radiant heater lineup.
- Consistent Fuel Draw Performance — A correctly functioning suction pipe maintains steady fuel flow to the burner assembly; a cracked or degraded pipe can introduce air into the fuel line and cause inconsistent ignition or burner lockout.
- Fuel System Safety — Combustion equipment demands leak-free fuel line components; using a genuine OEM suction pipe rated for the correct fuel type and pressure range reduces the risk of fuel weeping or vapour loss at the connection point.
The suction pipe is responsible for drawing fuel from the heater's tank or fuel supply and routing it toward the burner assembly. It forms a critical link in the fuel delivery circuit — if the pipe cracks, deforms, or develops a leak, the burner may lose prime, run erratically, or fail to ignite altogether. Replacing a worn or damaged suction pipe with a genuine OEM part restores proper fuel draw and helps the heater maintain the steady, efficient heat output it was designed to deliver.
