The Wacker Neuson Clamp is a genuine OEM component designed for the HI-series indirect-fired air heaters, including the HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, and HI 400HD G models. As a factory-sourced part, the meets the exact material and dimensional specifications set by Wacker Neuson for these heater units. Whether you are performing routine maintenance or replacing a failed clamp on a diesel indirect heater, this part ensures a secure, leak-free connection that keeps your heating system operating as intended. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's exact tolerances for clamping force and material grade, ensuring a secure hold on heater hose or duct connections without over-compression or slippage.
- Direct-Fit Replacement: — Engineered to drop into the original clamp position with no rework to surrounding hardware or fittings.
- Broad HI-Series Compatibility: — Fits HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, and HI 400HD G indirect-fired air heaters in both diesel and gas configurations.
- Maintains Combustion Circuit Integrity: — A properly seated clamp keeps fuel, air, or exhaust routing secure; a loose or cracked clamp can allow leaks that degrade heater output or create unsafe operating conditions.
- Fuel and Exhaust System Safety: — On indirect-fired heaters, clamp integrity is critical to containing combustion gases within the heat exchanger circuit, keeping exhaust out of the heated air stream.
On an indirect-fired air heater, clamps are used to secure hose, duct, and tube connections throughout the fuel delivery, combustion air, and exhaust routing circuits. A correctly tensioned clamp maintains a sealed connection under the vibration and thermal cycling that occurs during normal heater operation. When a clamp loosens, corrodes, or cracks, the resulting leak can reduce heating efficiency, cause fuel loss, or allow combustion gases to migrate where they should not — making prompt replacement important on any working heater.
