A Grommet used in an air cooler is a small, circular component made of rubber or elastomer material. It is designed to provide a seal or protection for various openings or passages in the air cooler. The grommet typically has a hollow cylindrical shape with an inner diameter that matches the outer diameter of the component it is inserted into.Attributes:• Offers excellent electrical insulation properties thereby minimizing the risk of short circuits or electrical hazards• Protects wire insulation from abrasion and wear caused by friction with surrounding materialsApplications:A Grommet is used to prevent the wires from being damaged or chafed by the sharp edges of the holes they pass through.
