Wacker Neuson 1000151191 Back Flow Filter Cover

The Wacker Neuson Back Flow Filter Cover is a genuine OEM component designed for the TH627 hydronic surface heater. Sourced directly from Wacker Neuson, this cover meets the exact specifications of the original part installed at the factory. If your TH627 is showing signs of filter housing damage or a compromised cover, the is the correct replacement to restore the system to proper working order.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's exact dimensional and material standards, ensuring the cover seats and seals as intended on the back flow filter housing.
• Direct-Fit Replacement — Designed to drop into the existing filter assembly on the TH627 without additional modification to the housing or mounting points.
• Confirmed TH627 Fitment — Verified for use with the Wacker Neuson TH627 hydronic surface heater (418-02 parts list).
• Protects Filter Integrity — A properly seated cover keeps the back flow filter enclosed and free from contamination, allowing the heating system's fluid circuit to function without restriction or debris ingestion.
• Fuel and Fluid System Safety — On hydronic heating equipment, maintaining a secure filter cover prevents uncontrolled fluid exposure and supports safe, leak-free operation of the heating circuit.

The back flow filter cover encloses the filter element within the fluid return circuit of the hydronic surface heater, protecting it from physical damage and external contamination. Without a correctly fitted cover, the filter is exposed to debris that can clog the circuit and restrict fluid flow through the heating system. A cracked, missing, or improperly seated cover can lead to reduced heating output, contaminated fluid, and potential damage to downstream components in the heating loop.
