# Mechanical Seals for Reefer Containers

Unlike insulation panels or foam linings, mechanical seals for reefer containers are precision components forming a gas- and liquid-tight interface between the refrigeration unit and the container wall. They prevent refrigerant leakage and stop warm outside air from entering the cargo space – either failure would undermine temperature stability and drive up energy consumption. In international shipments of perishables such as food, pharmaceuticals, or cut flowers, the integrity of these seals is directly tied to cold chain compliance and food safety requirements. Faulty seals rank among the most common causes of temperature excursions in reefer containers and are therefore checked systematically during pre-trip inspections. They are entirely distinct from customs seals, which secure the container against unauthorised access and serve a regulatory rather than technical function.
