The Wacker Neuson Cap is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45 series radiant heaters. Sourced directly from Wacker Neuson, this cap matches the original part specification, ensuring a correct, trouble-free installation with no guesswork on fit or compatibility. It is the same part supplied on the production line, so you can be confident it will seat, seal, and function exactly as intended on your machine.
Key Features
- Genuine OEM Construction: — Manufactured to the original material and dimensional specification, so the cap maintains the correct fit and retention characteristics critical to heater performance.
- Direct Drop-In Replacement: — Designed to install in place of the original part on HDR 155 and HDR 45 radiant heaters, using the same mounting points and interface as the factory-installed component.
- Confirmed HDR Series Fitment: — Verified compatible with the HDR 155 Direct Fired Radiant Heater and the HDR 45, covering both models in the Wacker Neuson direct-fired radiant heater range.
- Protects Internal Components: — A correctly fitted cap keeps contaminants, moisture, and debris out of the port or assembly it covers, preserving the integrity of the components beneath and extending service intervals.
- Fuel System and Heater Integrity: — On direct-fired radiant heating equipment, caps that seal fuel or combustion-related ports are critical to safe, proper operation; using the correct OEM part ensures compliance with the original design intent.
A cap on direct-fired radiant heating equipment serves as a protective closure for a port, fitting, or opening within the heater assembly. Its job is to prevent contaminants, air, or moisture from entering a sealed system — whether that is a fuel connection, a fluid port, or an inspection point. When a cap is cracked, missing, or incorrectly sized, it can compromise the seal of the system it protects, potentially leading to leaks, contamination, or irregular heater operation. Replacing a damaged or missing cap with the correct OEM part restores the intended seal and keeps the heater running as designed.
