The Wacker Neuson Nipple Fitting is a genuine OEM component designed for the HSH700, E2200, and E3000 ES series hydronic surface heaters and ground heaters. Sourced directly from Wacker Neuson, this fitting carries the same part number and specification as the original installed at the factory, so you get a direct, confident connection into existing fluid lines. It is compatible across a broad range of E2200 and E3000 ES configurations, including lift bail, generator-equipped, and extended-hose variants, as well as the HSH650 and HSH700G models.
Key Features
- OEM-Grade Sealing Integrity — Manufactured to Wacker Neuson's pressure and material specifications for hydronic fluid circuits, ensuring a leak-free connection in hot-fluid heating applications.
- Direct Thread-Compatible Replacement — Matches the original thread form and sizing so it seats cleanly into the existing port without reworking fittings or adapters.
- Broad Fitment Coverage — Compatible with HSH700G, HSH650, E2200 (all variants), and E3000 ES hydronic surface heater and ground heater series.
- Preserves System Flow Performance — A cracked, corroded, or stripped nipple fitting disrupts fluid flow and pressure balance throughout the heating circuit; replacing it restores proper hydronic circulation.
- Fuel and Fluid System Safety — Fittings in pressurized hydronic circuits are a critical seal point; using a correctly rated OEM fitting eliminates the risk of weeping joints or connection failure under operating pressure.
A nipple fitting serves as a threaded connector within the hydronic fluid circuit of a surface heater or ground heater, joining sections of hose, pipe, or components that carry heated fluid through the system. When the fitting is damaged, corroded, or cross-threaded, the pressurized fluid circuit can develop leaks that compromise heating output and create a safety hazard on the worksite. Replacing a failed nipple fitting with the correct OEM part restores the integrity of the fluid path and keeps the heating system operating at its intended pressure and flow rate.
