Container door seals are rubber gaskets specially designed for shipping container doors, providing a tight, weatherproof seal between the door and frame.
Made mainly from durable EPDM rubber, they offer excellent resistance to water, salt spray, UV, ozone and extreme temperatures, preventing rain, dust and moisture from entering during transport and storage.
With good flexibility and compression resistance, they ensure a secure, airtight closure for standard shipping containers, refrigerated containers and various storage containers. These seals effectively reduce leakage and protect cargo, widely used in marine, logistics and container manufacturing industries.
We supply a wide range of container door seal extrusions in both J and H shapes – ideal for replacing worn or damaged door rubbers and extending the life of old shipping containers.
Designed to fit most container types, these seals provide a secure, watertight barrier. Made from durable EPDM rubber, they deliver superior sealing performance, excellent weather and ozone resistance, and outstanding durability even in extreme temperatures.
With a longer life expectancy than standard rubbers, these seals reduce the need for frequent replacements, saving time and money over the long term.
The precision-tooled H section profile offers enhanced sealing compared to standard alternatives. Engineered for strength and reliability, it ensures a watertight solution that performs under demanding marine and shipping conditions.
While EPDM is our primary material, we can also manufacture seals in nitrile for specialist applications requiring alternative rubber properties.
High-performance container door seals make it easy to restore old containers, keeping them protected and fully functional for years to come.
Certification and Specifications
All concrete pipe gaskets must meet certain classes of ASTM C1619, depending on the specifications for a project. Generally, sanitary projects will require C1619 Class A (standard rubber) or B (oil-resistant rubber) and stormwater projects will reference C1619 Class C (standard) or D (oil-resistant).
Our factory has been ISO 9001 certified since 2005. In subsequent years, we have successively obtained ISO 14001, CE, EN 681 and SGS certifications, as well as other internationally recognized qualifications.
What materials are your container door seals made from?
We manufacture our container door seals primarily from durable EPDM rubber, valued for its resistance to weather, ozone, and temperature extremes. For specialized applications, we also offer seals made of nitrile rubber, ensuring you receive the right material for your specific sealing needs.
Do you offer customized container door seals for unique specifications?
Yes, we provide tailored solutions backed by our professional R&D team. Whether you require specific profiles, hardness, or materials, we create customized rubber seal strips that meet your technical requirements as leading rubber seal manufacturers.
How should I install container door seals for optimal performance?
Proper installation requires cleaning the container door frame and fitting the gasket securely within the door channels or mounting grooves. Our seals in J and H shapes are designed for easy installation and to ensure consistent compression, improving sealing effectiveness throughout the seal’s service life.
Can you support large-scale orders and timely delivery for industrial projects?
Absolutely. With our 2,178,000-square-foot production base and multiple extrusion and compression molding lines, we efficiently handle both small-batch and large-volume orders. We are a trusted rubber molding manufacturer ensuring timely supply of durable waterproof rubber seal strips for your project needs.
