Это резиновое контактное уплотнение для автомобилей обеспечивает герметизацию за счет упругого контактного сжатия. Оно эффективно блокирует проникновение пыли и влаги, предотвращает утечку жидкостей и снижает небольшую вибрацию между сопрягаемыми деталями автомобиля. Мы предлагаем варианты из EPDM, NBR и силикона, а также изготовление по индивидуальным формам и размерам для различных уплотнительных соединений автомобиля.
