The Wacker Neuson Drain Coupling is a genuine OEM component designed for the TH627 hydronic surface heater. As a factory-sourced part, it is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, trouble-free installation in the TH627's fluid circuit. Sourcing the directly means you are getting the same part that left the factory — no guesswork on compatibility.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's exact material and dimensional standards for the TH627 drain circuit, ensuring a leak-free seal under operating pressure and temperature.
• Direct-Fit Replacement — Engineered to connect directly into the existing drain port of the TH627, matching thread type, size, and sealing surface without any rework.
• Confirmed TH627 Fitment — Verified against the TH627 spare parts list (418-02), so you can order with confidence that this is the correct coupling for your machine.
• Fluid System Integrity — A properly functioning drain coupling allows controlled, clean draining of the hydronic fluid circuit during service — a failed or leaking coupling can result in uncontrolled fluid loss and system contamination.
• Genuine Part Traceability — Carries full Wacker Neuson OEM part status, supporting accurate service records for commercial and rental fleet equipment.

The drain coupling is a critical connection point in the hydronic surface heater's fluid circuit, providing a secure, sealable port for draining or servicing the heated fluid loop. It allows technicians to fully evacuate the system during maintenance, fluid changes, or winterization without disturbing other plumbing connections. When this coupling wears, cracks, or fails to seal, it can cause fluid leaks that compromise both the heating output of the system and the integrity of the surrounding components.
