The Wacker Neuson Union is a genuine OEM Union designed for the E3000, E3000 ES, E2200, S3000, HSH700G, HSH650, E700M, and Pureheat series hydronic surface heaters and ground heaters. As a direct OEM replacement, this Union is manufactured to the same specifications as the original component installed at the factory, ensuring a trouble-free fit within the existing fluid circuit. This part covers an extensive range of E3000 and E2200 configurations — including Lift Bail, generator-equipped, and TC variants — as well as HSH-series and Pureheat models. Keep part number on hand to minimize scheduled maintenance turnaround on your heating equipment.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and thread specifications, ensuring correct sealing performance within pressurized hydronic circuits.
- Direct Drop-In Replacement — Matches the original Union's thread pattern, port sizing, and body dimensions for straightforward installation with no reworking of adjacent fittings or hose ends.
- Broad Hydronic Heater Coverage — Compatible with E3000, E3000 ES, E2200, S3000, HSH700G, HSH650, E700M, and Pureheat series, covering both ground heater and hydronic surface heater configurations.
- Fluid Circuit Integrity — A correctly seated Union maintains leak-free connections in the hydronic loop; a failed or damaged union can cause coolant loss, pressure drop, and reduced heating output across the hose run.
- Wide Configuration Support — Covers Lift Bail, generator-equipped, TC, and standard variants within the E3000 and E2200 families, making 5000168058 a versatile stocking part for fleets running multiple heater configurations.
A Union is a threaded pipe or hose fitting that allows two sections of a fluid line to be connected and disconnected without rotating either line — critical in a hydronic heating system where the fluid loop must be serviceable in the field. In ground heaters and hydronic surface heaters, the Union sits within the heated-fluid circuit, maintaining a sealed, pressure-rated junction between hose runs, manifolds, or pump connections. When a Union cracks, corrodes, or develops a compromised seal, it allows heated fluid to escape the loop, causing pressure loss, reduced heat transfer to the ground or surface blanket, and potential damage to the pump or boiler from running dry.
