The Wacker Neuson Fitting is a genuine OEM component designed for HDR and HI series heaters, including the HDR 155 Direct Fired Radiant Heater, HDR 45, HI 90HD, and HI 120. Sourced directly from Wacker Neuson, this fitting matches the original equipment specification so installation is straightforward and connections seal correctly the first time. Confirm your model number before ordering to ensure an exact match with your unit.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring the fitting holds the correct pressure rating for fuel or fluid delivery in your heater system.
- Drop-In Replacement — Matches the original port threading and connection geometry, so it installs directly into the existing fitting location without rework or adapters.
- Broad HDR & HI Series Coverage — Compatible with the HDR 155 Direct Fired Radiant Heater, HDR 45, HI 90HD, and HI 120, covering both direct fired radiant and indirect fired heater applications.
- Leak-Free Fluid Management — A correctly seated fitting maintains consistent fuel or fluid flow through the heater circuit; a cracked, stripped, or deteriorated fitting risks pressure loss, leaks, and unreliable heat output on the jobsite.
- Fuel System Integrity — In heater applications, fitting condition is directly tied to safe fuel handling; using a correctly rated OEM fitting helps maintain the integrity of the fuel circuit and supports safe heater operation.
A fitting is a threaded or push-connect junction used to route and seal fuel, fluid, or air lines within the heater's internal circuit. In direct fired radiant and indirect fired air heaters, fittings keep fuel delivery lines properly connected between the tank, pump, and burner assembly. When a fitting cracks, strips, or begins to weep, it disrupts fuel flow and can cause inconsistent burner performance or create a leak point in the fuel system — making prompt replacement essential for both performance and safety.
