The profile helps control water, wind, impact, and noise and can be customized by length, color, cross-section, tolerance, corners, joints, and packaging.
This co-extruded EPDM container door seal strip is a flexible multi-fin profile for compatible cargo container doors. The illustrated cross-section is 80 mm wide, black as standard, and available in 60–75 Shore A, with 70 ±5 Shore A as the standard specification. It helps control water, wind, impact, and noise at the door perimeter.
Co-Extruded EPDM Container Door Seal Strip with 80 mm Profile
The EPDM container door seal strip forms a continuous sealing interface between a compatible cargo door and its frame. Its 80 mm cross-section includes multiple longitudinal fins that create several contact zones when the door closes. Additional marked dimensions include 45 mm, 25 mm, 20 mm, and 10 mm. The profile is manufactured by co-extrusion and can be supplied in continuous lengths for cutting, joining, and perimeter installation. Black is the standard color, while other colors are available upon request. The listed hardness range is 60–75 Shore A, with 70 ±5 Shore A as the standard specification. Final compatibility depends on the mounting channel, compression, corner construction, and door alignment.

Applications
This co-extruded EPDM seal strip is designed for installation around compatible cargo container door perimeters. It can be fitted along the vertical and horizontal sides of a door assembly, with formed or joined corners completing the sealing path. Compression of the longitudinal fins helps restrict rainwater, wind, dust, and outside air while cushioning contact and reducing noise around the closed door. The profile can be evaluated for container production, refurbishment, maintenance, and seal replacement. Related custom EPDM profiles may also be developed for automotive doors and windows, electrical appliances, machinery, construction assemblies, and household products when the required geometry, installation method, and operating conditions are provided.
Material and Performance Considerations
The confirmed material is EPDM, with an available hardness range of 60–75 Shore A and a standard specification of 70 ±5 Shore A. The listed temperature range is -40°F to 248°F (-40°C to 120°C), the specific gravity is 1.2–1.35 g/cm³, and the tensile strength is 10 MPa. Suitability must still be evaluated according to compression, weather exposure, contact media, cleaning agents, mechanical cycling, and installation conditions. Oil, fuel, solvents, or other chemical exposure must be disclosed before compound approval. Installed sealing performance also depends on profile geometry, dimensional consistency, door alignment, corner joints, compression distribution, and surface contact.
Customization and Manufacturing
The confirmed production process is co-extrusion. Custom container door seals can be evaluated from a 2D cross-sectional drawing, 3D model, physical sample, or complete door-channel dimensions. Configurable details include profile geometry, wall and fin dimensions, supplied length, EPDM specification, Shore A hardness, color, cross-sectional tolerance, surface finish, corner construction, jointing method, and packaging. The illustrated profile has an 80 mm overall width, while other sizes can be developed according to customer requirements. Prototype sections can be evaluated for installation, retention, door closing, compression, corner fit, and recovery. Tooling, MOQ, samples, and lead time are confirmed after technical review.
Quality and Sourcing Considerations
Before ordering, confirm the complete cross-section, dimensions, RMA tolerance requirements, EPDM specification, Shore A hardness, color, supplied length, mounting channel, corner design, jointing method, quantity, and operating conditions. Agreed inspection items may include profile width, fin height, base dimensions, wall thickness, hardness, surface condition, profile continuity, straightness, deformation, cuts, and joint quality. A representative section should be installed on the intended door and evaluated for retention, closing force, compression, recovery, corner fit, and visible gaps. Packaging should protect the coiled profile from crushing, sharp bends, contamination, surface damage, and permanent deformation during storage and transportation.

Frequently Asked Questions
What does an EPDM container door seal strip do?
The profile creates a compressed sealing interface between a compatible container door and its frame. Its multiple longitudinal fins help restrict water, wind, dust, and outside-air ingress. The flexible structure can also cushion contact and reduce noise. Actual performance depends on correct profile selection, installation, compression, corner construction, and door alignment.
What are the confirmed dimensions of this profile?
The overall profile width is 80 mm. Other marked dimensions include 45 mm, 25 mm, three indicated 20 mm sections, and a 10 mm lower-profile dimension. Supplied length can be customized. Cross-sectional dimensions are produced to RMA Standard Cross-Sectional Tolerance E2 unless another tolerance is agreed.
What hardness is available for the EPDM seal?
The available hardness range is 60–75 Shore A, while 70 ±5 Shore A is the standard specification. The selected hardness should provide suitable installation flexibility, profile retention, compression, recovery, and door-closing force. A different hardness can be evaluated according to the required cross-section and operating conditions.
How is the container door seal manufactured?
The confirmed manufacturing method is co-extrusion, which produces the continuous profiled strip. The required cross-section, compound arrangement, dimensions, tolerances, surface condition, and supplied length must be defined before production. Manufacturing feasibility should be reviewed when the existing profile is modified or a completely new section is required.
Can the color, length, and cross-section be customized?
Yes. Black is the standard color, and other colors are available upon request. The cross-section, fin arrangement, base geometry, length, hardness, tolerance, corners, joining method, surface finish, and packaging can also be customized. A complete specification or physical sample is required for technical evaluation.
Are samples, tooling, MOQ, and lead time available?
Sample availability, tooling requirements, MOQ, and lead time are available upon request. These details depend on whether the existing 80 mm profile is suitable or a custom co-extruded profile is required, together with the selected compound, hardness, color, tolerance, supplied length, corner construction, inspection plan, and order quantity.
Request Product Evaluation
Provide the required cross-section, door-channel dimensions, perimeter length, EPDM specification, Shore A hardness, color, tolerances, corner arrangement, installation method, contact media, operating conditions, and estimated quantity. A 2D drawing, 3D model, or physical sample will support profile comparison, manufacturing review, prototype preparation, and an accurate quotation.
