Container door seals are rubber gaskets with PVC 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
REQUEST A QUOTEWe 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.
FAQ
What materials are used in your Container Door Seals?
We manufacture our Container Door Seals primarily from durable EPDM rubber and PVC, with nitrile options for specific applications. These materials ensure excellent resistance to water, salt spray, UV, and extreme temperatures, making them reliable rubber gaskets for harsh marine and logistics environments.
Can you customize the shape and size of Container Door Seals for different containers?
Yes, we offer Container Door Seals in both J and H section extrusions to fit various door profiles. Our production flexibility allows us to deliver custom profiles meeting your requirements, supporting your projects with high-precision rubber sealing solutions tailored for shipping and storage containers.
How should I maintain Container Door Seals to ensure lasting performance?
To maintain our Container Door Seals, regular inspection for wear or damage is recommended. Clean the seals periodically to remove dirt and salt deposits, especially in marine environments. Properly maintained seals continue to provide airtight, weatherproof protection, extending container lifespan while reducing maintenance costs.
Do you provide sealing solutions suitable for concrete pipe or other industrial applications?
Yes, aside from Container Door Seals, we produce a full range of rubber sealing solutions for concrete pipe, including O-rings and profile gaskets. Our ISO-certified manufacturing and experienced R&D team ensure reliable sealing for various industrial uses beyond container doors, supporting your broader project demands.
