The Wacker Neuson 3/8 NPT 3 Long Brass Nipple is a genuine OEM fitting designed for the HI1000, HI900DGM, HI260, and E1250P series indirect air heaters and hydronic heating units. Sourced directly from Wacker Neuson, this brass nipple matches the original specification for thread size, length, and material — ensuring a leak-free connection in demanding heating system applications. Verified fitment spans multiple HI-series heater configurations, including diesel, DGM electric brake, and surge brake variants, so you can order with confidence that is the correct part for your machine.
Key Features
- Corrosion-Resistant Brass Construction — Brass material resists the heat, moisture, and fuel-system fluids common in indirect air heater plumbing, maintaining a secure seal over the long term.
- 3/8 NPT Thread, 3-Inch Length — Matches the original thread form and pipe length exactly, threading directly into existing ports without adapters or modification.
- Genuine Wacker Neuson OEM Part — Manufactured to Wacker Neuson's own specification, part number 5200008970 delivers the same fit and function as the part that left the factory.
- Broad HI-Series Heater Coverage — Confirmed fitment across HI1000, HI1000DGM, HI900DGM, HI260, and E1250P models, covering diesel, electric brake, and surge brake configurations.
- Fuel and Fluid System Integrity — A properly seated brass nipple maintains the pressure integrity of the heater's fluid circuit; a worn or damaged nipple risks leaks that can shut down heating output on the jobsite.
- Fuel System Safety — Correct thread engagement and material compatibility are critical in heater fuel and fluid lines; using the OEM-specified fitting helps prevent leaks that could create a fire or burn hazard.
A pipe nipple is a short length of threaded pipe used to connect two fittings, valves, or ports within a fluid or fuel circuit. In Wacker Neuson indirect air heaters and hydronic heating units, brass nipples like the 5200008970 form part of the plumbing network that routes diesel fuel or heat-transfer fluid between the burner, tank, and heat exchanger. If a nipple corrodes, cracks, or develops a thread leak, the heater's fluid circuit loses pressure, which can cause the unit to shut down or, in a fuel line, create a leak hazard — making prompt replacement with the correct OEM part essential to keeping the heater operating safely and efficiently.
