The Wacker Neuson Nipple Fitting is a genuine OEM component designed for the HSH350 Hydronic Surface Heater and E1100 Ground Heater series. Sourced directly from Wacker Neuson, this fitting is manufactured to the same specifications as the original part installed at the factory. The is confirmed to fit HSH350 and E1100 surface and ground heater models, making it a straightforward, stock-matching replacement. When you need to restore a fluid connection in your heating system, using the correct OEM nipple fitting ensures a secure, leak-free seal without guesswork.
Key Features
- OEM-Matched Thread and Dimensional Tolerances — Manufactured to exact thread pitch and diameter specifications, ensuring consistent seating and a pressure-rated seal within the hydronic or ground heating circuit.
- Direct-Swap Installation — Threads directly into the existing port without modification, matching the original connection point on HSH350 and E1100 heater plumbing systems.
- Confirmed Fitment for HSH350 and E1100 Heater Series — Compatible with HSH350 Hydronic Surface Heaters and E1100 Ground Heaters, including 50Hz DG surface heater variants.
- Leak-Free Fluid System Integrity — A correctly installed nipple fitting maintains proper fluid pressure and flow throughout the heating circuit; a damaged or worn fitting can cause fluid loss and heater shutdown.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM parts program, part number 5200003944 is the same component used in original equipment assembly.
A nipple fitting is a short threaded connector used to join two sections of pipe or hose within a fluid circuit. In hydronic surface heaters and ground heaters like the HSH350 and E1100, these fittings carry heated fluid through the system to deliver consistent thermal output across the heating surface. When a nipple fitting cracks, corrodes, or develops thread damage, it can cause fluid leaks that reduce system pressure, compromise heating efficiency, and force an unplanned shutdown — particularly damaging in cold-weather concrete curing or freeze-prevention applications where continuous heat is critical.
