Every dry van trailer relies on door seals to keep cargo safe by keeping out outdoor moisture, dust and road debris. Rubber and EPDM are the most common materials used for these seals, but they degrade steadily with regular door use and long haul runs. Extreme sunlight, frequent weather changes and rough job-site handling usually lead to cracked rubber, flattened seals, built-up grime and peeling edges. These small defects leave tiny gaps on door seams. Once wind and water get inside the trailer, freight can easily get spoiled, resulting in extra costs for logistics companies.
Simple, regular upkeep is key to keeping trailer door seals functional and stopping premature wear. Workers should take time to clean off dirt, ice and buildup on the seals and check for damage or loose sections during daily checks. A light silicone coating protects the rubber from sun damage and keeps it flexible all year long. Rough handling is one of the biggest causes of seal damage, so slamming doors or prying open frozen doors should always be avoided. When seals become worn or damaged, swapping them out right away ensures a secure door seal, cuts down on repeated repairs, and helps avoid cargo damage during transport.
