The Wacker Neuson Bleed Screw is a genuine OEM component designed for the HSH700 and HSH650 hydronic surface heaters. Sourced directly from Wacker Neuson, this bleed screw is an exact match to the original part installed at the factory, ensuring a correct and trouble-free service. Compatible with the HSH700G and HSH650 models, it is the right choice when servicing or maintaining the fluid circuit on these hydronic heating systems.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original thread pitch and material specifications, ensuring a fluid-tight seal when installed correctly in the heater circuit.
- Direct Drop-In Replacement — Threads directly into the existing port on HSH700 and HSH650 hydronic surface heaters with no rework or modification to the housing required.
- Confirmed HSH Series Fitment — Verified compatible with the HSH700G and HSH650 models, covering both current hydronic surface heater variants in the Wacker Neuson HSH lineup.
- Maintains System Pressure Integrity — A correctly seated bleed screw keeps the hydronic circuit sealed under operating pressure; a damaged or missing screw allows air ingestion and fluid loss that disrupts heat output.
- Fuel and Fluid System Safety — As a pressurized-circuit component, using the correct OEM specification screw is important for preventing unintended leaks in the heating fluid loop during operation.
A bleed screw is a small but critical valve point in a hydronic heating circuit. Its primary job is to allow trapped air to be purged from the fluid loop during filling or servicing, ensuring the system circulates heated fluid efficiently without air pockets that reduce heat transfer. When a bleed screw is cracked, cross-threaded, or missing entirely, the circuit cannot be properly bled, leading to reduced heating performance and potential fluid leaks at the service port. Replacing a worn or damaged bleed screw with the correct Wacker Neuson 5000176519 restores the integrity of the system and allows the HSH700 or HSH650 to deliver consistent, full-output surface heating.
