The Wacker Neuson Nipple Fitting is a genuine OEM component designed for the E3000, E2200, HSH700G, HSH650, and E700M series hydronic surface heaters and ground heaters. As a direct factory replacement, this fitting is produced to Wacker Neuson's exact specifications, ensuring a secure, leak-free connection within the machine's fluid circuit. It is compatible across a wide range of E3000 and E2200 configurations, including ground heater, hydronic surface heater, lift bail, and generator variants. Always confirm your specific machine number against the fitment list to ensure this part matches your unit before ordering.
Key Features
- Genuine OEM Fluid-Tight Construction — Manufactured to Wacker Neuson's exact thread form and material grade, delivering the leak-free seal that hydronic heating circuits demand.
- Direct-Connect Replacement — Matches the original port geometry and thread specification, allowing a straightforward swap into existing fluid line connections without reworking adjacent fittings.
- Broad Fitment Across Heating Equipment Families — Confirmed fitment on E3000, E3000 ES, E2200, HSH700G, HSH650, and E700M series units, covering ground heater and hydronic surface heater configurations with and without lift bail or onboard generator.
- Maintains Circuit Integrity — A correctly seated nipple fitting keeps heated fluid flowing at the designed pressure and flow rate; a damaged or leaking fitting starves downstream components and compromises heating output.
- Fluid System Safety — Proper fitting integrity prevents pressurized hot fluid from escaping the closed loop, protecting operators and surrounding equipment from uncontrolled leaks during operation.
A nipple fitting is a short threaded connector used to join two sections of pipe, hose, or fittings within a fluid circuit. In Wacker Neuson hydronic heaters and ground heaters, these fittings are part of the closed-loop system that circulates heated fluid to warm concrete slabs, soil, or surfaces in cold-weather construction applications. When a nipple fitting cracks, strips, or corrodes, the circuit loses pressure and heated fluid can escape, reducing heating efficiency and creating a potential hazard on the worksite. Replacing a worn fitting promptly with the correct OEM part restores circuit integrity and keeps the heating system operating at full capacity.
