The Wacker Neuson Pin Plug is a genuine OEM component designed for the HI260 indirect-fired air heater and HSH 380S and HSH 380B hydronic surface heater series. As a direct OEM replacement, part is manufactured to the exact tolerances and connector specifications of the original, ensuring a correct, secure fit in the electrical circuit where it was engineered to serve. Verified fitment covers HI260 heaters with and without a tank, as well as HSH 380S natural gas/propane models with a generator and HSH 380B natural gas/propane models without a generator.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to the original pin-and-socket contact specifications, ensuring correct conductivity and a secure, corrosion-resistant connection in the heater's electrical circuit.
- Drop-In Replacement — Matches the original connector housing geometry and pin configuration, so it seats and locks exactly as the factory part does — no modification to the harness or housing required.
- Broad Heater Family Coverage — A single part number covers HI260 indirect-fired air heaters (with and without tank) and HSH 380S/380B hydronic surface heaters, simplifying parts sourcing across your fleet.
- Protects Heater Control Continuity — A worn or damaged pin plug can interrupt control signals or power delivery, causing erratic burner behavior or a complete heater shutdown on the worksite — a correctly seated plug keeps the electrical system operating as designed.
- Fuel-System and Ignition Safety Relevance — In combustion heating equipment, a compromised electrical connector can affect fuel valve or ignition control signals; using the correct OEM pin plug helps maintain the intended safety interlock behavior of the heater.
The pin plug is an electrical connector component that forms a secure, removable junction between two sections of the heater's wiring harness or between the harness and a control component. It transfers power or control signals across that junction while protecting the contact pins from moisture, vibration, and mechanical stress. When the plug becomes damaged, corroded, or develops a loose fit, the resulting poor connection can cause intermittent faults, failed ignition sequences, or loss of burner control — making prompt replacement essential for safe and consistent heater operation.
