## Summary description

Replacement sealing gasket designed for use with GEKO oil heaters equipped with a thermostat and rated at 40 kW. This gasket provides a tight seal between heater components to prevent oil and air leaks, support safe operation, and maintain thermal efficiency.

## Long description

Sealing Gasket for GEKO Oil Heater with Thermostat 40 kW is a replacement sealing element designed to restore tight joints between housing components and fluid passages in compatible GEKO oil-fired heaters rated at 40 kW. The gasket creates a reliable barrier that minimizes oil seepage and air ingress, helping to maintain correct combustion conditions and steady thermal output. It is intended for maintenance and repair of workshop or industrial heating units and fits units that use the same gasket profile and dimensions.
Advantages
This sealing gasket delivers a close fit to reduce leakage paths and preserve system pressure and temperature stability. It is manufactured from materials selected for oil resistance and temperature tolerance, which supports long service intervals and consistent sealing performance. By restoring proper sealing, the gasket helps to reduce the risk of contamination of surrounding components and contributes to predictable heater behaviour and maintenance outcomes.
Suitable for
Repairing GEKO oil heaters rated at 40 kW that use the matching gasket profile
Routine maintenance during gasket replacement to prevent oil and air leaks
Workshop and industrial heating systems requiring component-level sealing restoration
Key specifications
Function: sealing gasket for oil heater components
Compatibility: designed for GEKO oil heaters with thermostat and 40 kW nominal power (units using the same gasket shape)
Material properties: oil-resistant and temperature-tolerant sealing material
Application environment: industrial and workshop heating systems
How to use
Before installation, ensure the heater is fully cooled and depressurized according to the manufacturer’s service instructions. Remove the old gasket and clean mating surfaces to remove oil, deposits and debris. Position the replacement sealing gasket in the correct orientation and reassemble the components, tightening fasteners to the torque values specified by the heater manufacturer. After installation, inspect for leaks during a controlled restart and verify stable operation of the thermostat and burner.
Usage recommendations
Replace the gasket with the heater cold and following safety procedures. Use only the gasket profile that matches the original part to ensure correct sealing. Inspect surrounding parts such as flanges, seats and fasteners for wear or damage and replace them as needed to maintain long-term sealing effectiveness.
