Wacker Neuson 5000168649 Tube Connector

The Wacker Neuson Tube Connector is a genuine OEM component designed for the HX100 Heat Exchanger and the Pureheat Hydronic Heater series, including Oil Burner, Gas Burner, and Diesel Hydronic Air Heater configurations. As a direct factory replacement, this tube connector restores the sealed fluid pathway within the hydronic heating circuit, ensuring system pressure and flow are maintained to specification. Sourcing the correct OEM part is especially important in hydronic heating systems, where a mismatched connector can compromise the integrity of the entire loop and lead to heat loss or fluid leaks.

Key Features

• OEM-Matched Sealing Geometry — Manufactured to the exact bore diameter and barb profile of the original, ensuring a leak-free connection within the hydronic fluid circuit.
• Direct Drop-In Replacement — Designed to connect inline without modification, mating precisely to the tubing already present in the HX100 and Pureheat systems.
• Broad Pureheat Series Coverage — Fits the HX100 Heat Exchanger, Pureheat Hydronic Heater (Oil Burner and Gas Burner), and the Hydronic Air Heater (Diesel) — one part number across the full family.
• Maintains Heating Circuit Efficiency — A correctly seated tube connector sustains consistent fluid flow through the heat exchanger; a cracked or loose connector causes pressure drop and uneven heat output.
• Fluid System Safety — In a pressurized hydronic loop, a failed connector can result in fluid loss and potential burn risk; using the OEM-spec connector keeps the system operating safely within its designed pressure range.
• Genuine Wacker Neuson Part — Supplied as genuine OEM stock, backed by Wacker Neuson's parts quality standards and traceable to part number 5000168649.

A tube connector serves as a junction fitting within the hydronic heating circuit, linking sections of fluid-carrying tubing so that heated liquid can circulate continuously through the system. In hydronic heaters like the Pureheat series, this flow is what transfers thermal energy to the air being discharged — any interruption to the sealed circuit directly reduces heating output. When a tube connector cracks, loosens, or degrades, coolant or heat-transfer fluid escapes the loop, causing the system to lose pressure, output inconsistent heat, or shut down on a fault condition.
