The Wacker Neuson Close Nipple 3/8 NPT Brass is a genuine OEM fitting designed for the HI1000, HI900DGM, HI260, and E1250P series indirect air heaters and hydronic heaters. Sourced directly from Wacker Neuson, this brass nipple matches the original part specification exactly, ensuring a leak-free, secure connection in the heating system's fluid or fuel plumbing. Compatible across multiple HI-series heater configurations — including diesel, DGM electric brake, and surge brake variants — part number covers a broad range of Wacker Neuson heating equipment.
Key Features
- Genuine OEM Brass Construction — Manufactured to Wacker Neuson's material specification, this brass nipple provides the corrosion resistance and pressure integrity required in heating system plumbing applications.
- 3/8 NPT Thread Compatibility — Machined to standard 3/8 NPT thread dimensions for a direct, thread-in installation with no chasing or reworking of existing ports required.
- Broad HI-Series Fitment — Fits HI1000, HI1000DGM, HI900DGM, HI260, and E1250P heater models, making it a single part solution across a wide range of Wacker Neuson heating equipment.
- Leak-Free Fluid Connection — A correctly fitted close nipple maintains sealed, uninterrupted flow in the heating circuit; a worn or damaged nipple risks fuel or coolant leaks that compromise heater output and safe operation.
- Fuel and Fluid System Safety — In diesel heating systems, fittings that carry fuel or heat transfer fluid must maintain full integrity under operating pressure and temperature; using the correct OEM part is essential to safe system operation.
A close nipple is a short threaded pipe fitting used to connect two female-threaded ports in direct, face-to-face contact with minimal gap between them. In Wacker Neuson indirect air heaters and hydronic heaters, fittings like this are used throughout the fuel supply and heat transfer plumbing circuits to route fluids between components. When a nipple corrodes, cracks, or develops a thread failure, it can cause fluid leaks that disrupt heating performance, create fire risk in fuel lines, or lead to system shutdown — making timely replacement with the correct OEM part critical to safe, continuous heater operation.
