The Wacker Neuson Elbow Fitting is a genuine OEM component designed for the E-series and HSH-series hydronic surface heaters and ground heaters, including the E1100, E2200, E3000, E3000 ES, E5000, HSH350, HSH650, and HSH700, as well as Pureheat, S3000, E700M, HP252, and BP45 Booster Pump models. Sourced directly from Wacker Neuson, this fitting is manufactured to the same specification as the original part installed at the factory, ensuring a correct, leak-free connection within the hydronic fluid circuit. With coverage across such a broad range of E-series and HSH-series configurations — including lift bail, generator, and TC variants — part number is the dependable choice for fleet operators and service technicians keeping multiple units in the field.
Key Features
- Correct Thread and Angle Specification — Manufactured to OEM dimensions, ensuring the elbow seats and seals properly within the hydronic plumbing circuit without rework or adaptation.
- Leak-Free Fluid Circuit Integrity — A correctly fitted elbow fitting maintains pressurized flow through the heating loop; a worn or damaged fitting risks fluid loss, pressure drop, and heater shutdowns on the job.
- Genuine Wacker Neuson OEM Part — Produced to the same material and dimensional standards as the original, giving you confidence that the fitting will perform across full operating temperature and pressure ranges.
- Broad E-Series and HSH-Series Coverage — Fits E1100, E2200, E3000, E3000 ES, E5000, HSH350, HSH650, HSH700, S3000, E700M, Pureheat, HP252, and BP45 configurations, including diesel, gas, generator, and lift bail variants.
- Simplified Serviceability — A direct OEM replacement means technicians can complete the repair quickly using standard fittings procedures, with no guesswork on compatibility across the wide range of supported models.
An elbow fitting is a directional pipe or hose connector that routes fluid flow through a change in angle — typically 45° or 90° — within a closed fluid circuit. In hydronic surface heaters and ground heaters, elbow fittings are critical junction points that keep heated glycol or water circulating through the hose network at the correct pressure and flow rate. When an elbow fitting cracks, corrodes, or its sealing surfaces degrade, the system loses fluid pressure, which triggers safety shutdowns, reduces heating output, or causes fluid leaks that can damage surrounding components and create hazardous working conditions.
