The Wacker Neuson Nipple Fitting is a genuine OEM component designed for the HSH350, Pureheat, E1100, and E3000 ES hydronic surface heater series. Sourced directly from Wacker Neuson, this fitting is built to the exact tolerances required for leak-free fluid connections in demanding jobsite heating applications. It is a direct-replacement part verified for compatibility across diesel, gas, and electric-powered variants within these hydronic heater families. Whether you are servicing an E1100 ground heater, a Pureheat hydronic air heater, or an E3000 ES surface heater, part number ensures a correct, secure fit every time.
Key Features
- OEM-Spec Sealing Geometry — Manufactured to Wacker Neuson's original thread profile and seating dimensions, ensuring a pressure-tight connection with no fluid weep or seepage at the joint.
- Drop-In Replacement — Threads directly into the original port without modification, matching the exact size, thread pitch, and shoulder depth of the factory-installed fitting.
- Broad Hydronic Heater Coverage — Confirmed fit across HSH350, Pureheat (diesel, gas, and oil-burner variants), E1100, and E3000 ES models, covering both ground-heating and surface-heating configurations.
- Critical for Fluid System Integrity — A sound nipple fitting maintains proper coolant or heat-transfer fluid flow throughout the system; a cracked or stripped fitting can cause pressure loss and heater shutdown in cold-weather operations.
- Fuel and Fluid System Safety — In hydronic heating systems carrying pressurized fluid, a correctly rated OEM fitting prevents uncontrolled leaks that could pose burn or fire hazards on site.
A nipple fitting is a short, threaded connector used to join two sections of pipe, hose, or port within a fluid circuit. In a hydronic surface heater, it forms part of the internal plumbing that routes heated fluid from the burner unit to the distribution hoses and back. When this fitting corrodes, cracks, or strips at the threads, the system loses the ability to maintain circuit pressure, causing heat output to drop or the unit to shut down entirely — a critical failure during cold-weather ground-thawing or concrete-curing operations.
