Air Inlet Heater Washer is a precision-formed sealing element placed between the air inlet heater and its mounting surface in an engine intake system. It distributes clamping force evenly, prevents air or gas leaks, and maintains a consistent seal under temperature changes and vibration. By ensuring a proper seal, it supports optimal heater function for improved cold-start performance and reliable engine operation.Attributes:• Withstands operational temperatures.• Withstands intake system pressure.• Compatible with standard heater housings.Applications: An Air Inlet Heater Washer is used in engine intake systems to seal the interface between air inlet heaters and mounting surfaces, ensuring proper heater operation and airflow control.
