The Wacker Neuson 5000183915 Nipple is a genuine OEM component designed for the HI and HDR series indirect-fired air heaters and direct-fired radiant heaters. As a factory-sourced part, it is manufactured to the exact specifications required by Wacker Neuson and fits a broad range of heater models including the HI 110D, HI 200D, HI 300D, HI 400HD D, HI 120HD, HI 90HD, HDR 115, HDR 155, and many others across the HI and HDR families. Sourcing the correct 5000183915 Nipple ensures the fluid or fuel passage connection it serves operates as originally engineered. Verify your model number before ordering to confirm compatibility with your specific unit.
Key Features
- Genuine OEM Fit and Material Grade — Sourced directly from Wacker Neuson, this nipple meets the exact thread form, diameter, and material specification used during original assembly — critical for maintaining leak-free connections in a pressurized fuel or fluid circuit.
- Drop-In Installation — Threaded to match the original port geometry, this nipple seats and torques to spec without modification to adjacent fittings or lines.
- Broad HI and HDR Series Coverage — Fits across the HI 90, HI 90HD, HI 110D, HI 120, HI 120HD, HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, HDR 45, HDR 115, HDR 155, HD 50, HD 70, and HI 35 heater models.
- Leak Prevention in Heating Applications — A worn, cracked, or cross-threaded nipple in a heater's fuel or fluid circuit can cause pressure loss or leaks that degrade heat output or prevent the unit from firing reliably. Replacing with the correct OEM part restores circuit integrity.
- Fuel System Integrity — Because this nipple is part of the heater's fuel or fluid pathway, using an exact-spec replacement matters for safe, consistent combustion performance in cold-weather jobsite heating applications.
A nipple is a short threaded fitting used to connect two sections of pipe, hose, or component ports within a fluid or fuel circuit. In indirect-fired and direct-fired heaters like the HI and HDR series, these fittings are found throughout the fuel delivery and coolant routing systems, where they maintain sealed, pressure-rated connections between components. When a nipple becomes damaged, corroded, or stripped, it can allow fuel or fluid to leak, disrupting heater operation and posing a safety concern in an active heating environment. Replacing it promptly with the correct OEM part restores the integrity of the circuit and keeps the heater performing as designed.
