The Wacker Neuson is a genuine OEM Nipple Fitting designed for Wacker Neuson hydronic surface heaters and ground heaters, including the HSH700G, HSH650, E2200, E3000 ES, E700M, and HP252 series. As a direct OEM replacement, this fitting is manufactured to the exact specification of the original part, ensuring a leak-free connection within the fluid circuit. It fits across the full range of E2200 and E3000 ES configurations, including lift bail variants, generator-equipped models, and the 700m hose hydronic surface heater. Keep part number on hand to minimize fluid system service time.
Key Features
- Genuine OEM Fluid-Tight Integrity — Manufactured to the original thread profile and sealing specification, this nipple fitting maintains the pressure integrity of the hydronic circuit — critical in a heating system where even a small leak disrupts fluid flow and output.
- Direct-Swap Replacement — Matches the original port size and thread type exactly, so it threads into the existing fitting location without reworking any connections or adapters.
- Broad HSH and E-Series Compatibility — Confirmed fitment across HSH700G, HSH650, E2200 (including 3kW generator and lift bail variants), E3000 ES, E700M, and HP252 hydronic surface and ground heater models.
- Protects Heating System Efficiency — A worn or cross-threaded nipple fitting can cause fluid loss, air ingestion, or pressure drop — all of which reduce heat output and can lead to pump damage in glycol-based heating circuits.
- Fuel and Fluid System Safety — Correct thread engagement and material grade matter in pressurized hydronic systems; using the specified OEM fitting helps prevent uncontrolled fluid release during operation.
A nipple fitting is a short threaded connector used to join two sections of pipe, hose, or component ports within a fluid circuit. In Wacker Neuson hydronic surface heaters and ground heaters, these fittings form the sealed junctions that keep heated glycol solution flowing continuously through the system's hose network. When a nipple fitting fails — through corrosion, thread damage, or cracking — the result is a fluid leak that reduces system pressure, starves the circuit of flow, and can cause the heating unit to underperform or shut down entirely. Replacing a damaged fitting promptly with the correct OEM part restores circuit integrity and keeps the heating system operating at full output.
