The Wacker Neuson Nipple Fitting is a genuine OEM component designed for the E2200, E3000, E3000 ES, HSH650, and HSH700 series hydronic surface heaters and ground heaters. As an authentic Wacker Neuson part, the is manufactured to the exact tolerances required to maintain leak-free fluid connections within the heating circuit. This fitting is confirmed compatible across a wide range of E3000 and E2200 configurations, including lift bail, generator, and temperature-controlled variants, as well as the S3000 and E700M series hydronic surface heaters.
Key Features
- Leak-Free Thread Engagement — Manufactured to OEM thread specifications, ensuring a secure, pressure-tight seal within the hydronic fluid circuit.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this fitting matches the original installed component exactly — same material grade, same thread form, same dimensions.
- Broad Fitment Across Heater Families — Compatible with E2200, E3000, E3000 ES, HSH650, HSH700G, S3000, and E700M hydronic surface heater and ground heater models in multiple configurations.
- Maintains Heating System Integrity — A correctly functioning nipple fitting keeps heated fluid flowing at designed pressure; a worn or damaged fitting can cause fluid loss, pressure drop, and loss of heating output.
- Direct Drop-In Replacement — Installs in the same position as the original, connecting directly into the existing fluid line or manifold port with no modification to surrounding components.
A nipple fitting is a short threaded connector used to join two sections of pipe or hose within a fluid system. In Wacker Neuson hydronic surface heaters and ground heaters, nipple fittings are critical junction points in the heated glycol circuit that transfers warmth to the ground blanket or surface panel. When a nipple fitting corrodes, cracks, or strips its threads, the result is a fluid leak that starves the system of the pressure needed to circulate heat effectively — replacing the fitting promptly restores full system performance and prevents further fluid loss or component damage.
