Wacker Neuson 1000028095 Drain Coupling

The Wacker Neuson Drain Coupling is a genuine OEM component designed for the TH627 hydronic surface heater. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original and installs as a direct replacement with no guesswork. If you're servicing or rebuilding the fluid circuit on your TH627, using the correct OEM drain coupling ensures a proper seal and leak-free operation every time.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the exact thread pitch, bore diameter, and material grade as the original, ensuring a pressure-tight connection in the hydronic fluid circuit.
• Direct-Fit Replacement — Connects directly to the drain port on the TH627 without additional adapters or modifications to existing fittings.
• Confirmed TH627 Fitment — Verified for the Wacker Neuson TH627 hydronic surface heater (418-02 spare parts list).
• Leak-Free Fluid Management — A properly seated drain coupling allows controlled, clean fluid drainage during service — a worn or cracked coupling can cause uncontrolled fluid loss and contamination of the work surface.
• Fluid System Safety — On hydronic heating systems, a secure drain coupling is critical to maintaining circuit pressure integrity and preventing scalding fluid from escaping during servicing.

The drain coupling serves as the controlled exit point for fluid in the hydronic circuit of the TH627 surface heater. It allows technicians to safely drain the system during maintenance, fluid changes, or winterization without disturbing other components. When this coupling is cracked, corroded, or improperly seated, it can result in uncontrolled fluid leaks, pressure loss in the heating loop, and potential damage to surrounding components or the work surface being heated.
