The Wacker Neuson is a genuine OEM Sight Gauge designed for the E3000, E2200, HSH650, HSH700, S3000, E700M, HP252, and Pureheat series hydronic surface heaters and ground heaters. As a direct OEM replacement sourced through the Wacker Neuson parts program, part meets the same specifications as the original component installed at the factory. This Sight Gauge fits an extensive range of configurations across the E3000 and E2200 families — including lift bail, generator, and temperature-controlled variants — as well as Pureheat diesel and gas burner models.
Key Features
- Genuine OEM Fluid-Level Accuracy — Manufactured to the same transparency and dimensional tolerances as the original, ensuring accurate visual readings of fluid level in the heating circuit.
- Direct-Mount Replacement — Designed to install in the same port and orientation as the factory-fitted gauge, with no modification to the reservoir or housing required.
- Broad Hydronic Heater Compatibility — Fits E3000, E2200, HSH650, HSH700, S3000, E700M, HP252, and Pureheat ground heater and hydronic surface heater configurations, covering both gas and diesel burner variants.
- Supports Proper Fluid Management — A clear, functioning sight gauge allows operators to confirm correct glycol/water mix levels at a glance, protecting the pump and heat exchanger from running low or dry.
- Prevents Costly Heating System Damage — A cracked, clouded, or missing sight gauge makes it impossible to monitor fluid levels, increasing the risk of pump cavitation and system overheating on the job.
A sight gauge provides a transparent window into the fluid reservoir of a hydronic heating system, allowing operators to visually confirm that the heating fluid — typically a glycol and water mixture — is at the correct operating level. On hydronic surface heaters and ground heaters like the E3000 and E2200 series, maintaining the right fluid level is critical: too little fluid starves the circulation pump and heat exchanger, leading to overheating or pump failure, while an undetected leak can bring the system down without warning. When the sight gauge becomes clouded, cracked, or begins to leak, it should be replaced promptly to restore safe and reliable fluid-level monitoring.
