Dishwasher door sealing gaskets are typically made from EPDM sponge material (with a hardness of approximately 35–45 Shore A) or silicone material (with a hardness of approximately 50–55 Shore A). All materials must pass ISO certification, offering outstanding waterproof sealing performance and high-temperature resistance to ensure reliable sealing during high-temperature washing cycles, prevent leakage of water and steam, and extend the service life of the equipment.
