If you are looking for a quality sealing strip for the doors of a shipping or refrigerated container, the DA25-A39-EO profile is a solution that will meet even the most demanding requirements. This specially developed rubber profile is designed to ensure perfect insulation of the interior space against moisture, dust, and temperature fluctuations.

Quick Specifications

• Weight: 1.8 kg
• Material: EPDM
• Length = 2500 mm

Key Parameters of the Gasket

The basic data speaks for itself. The gasket is made of EPDM material, a modern synthetic rubber with excellent resistance to weather conditions, UV radiation, and extreme temperatures. The profile length is 2500 mm, which precisely matches the dimensions of standard doors on most shipping and refrigerated containers. The weight of 1.8 kg reflects a robust yet easy-to-handle construction – the profile is strong enough to withstand frequent opening and closing of the doors, while you can comfortably work with it during installation.

Why Choose EPDM Material

EPDM (ethylene propylene diene monomer rubber) is a material that has earned a reputation for uncompromising durability in the field of sealing. Unlike conventional rubber, it retains its flexibility even at very low temperatures, typical for refrigerated containers, and at the same time resists high temperatures that can occur in direct sunlight. It does not lose its shape, does not crack, and requires no special maintenance. The long service life of EPDM gaskets means you invest once and have peace of mind for many years.

Detail B – The Precision That Makes the Difference

In technical drawings, you will often come across the designation “Detail B”. This illustrates a key element of the entire profile – the corner joint, the orientation of overlapping flaps, or the precise insertion of the cross-section blade into the door frame. It is precisely this detail that determines how the gasket adheres to the container structure and whether it can create a perfectly sealed space. Correct execution of Detail B ensures that the sealing strip follows the outline of the door frame without gaps or deformations. During installation, you can be sure that the profile will fit precisely into place and will not wobble even after thousands of opening cycles.

For Which Containers Is the Gasket Intended

The DA25-A39-EO profile is universally applicable for the doors of shipping and refrigerated containers. Thanks to its precise shaping, it is suitable both for standard shipping containers and for special refrigerated boxes where maintaining a constant temperature is absolutely essential. It will be appreciated by owners of storage containers, logistics companies, shipping companies, and individuals who have modified a container for their own needs – for example, as a mobile workshop, on-site facility, or seasonal storage.

Installation and Maintenance

Installing the gasket is simple and can be handled by a regular user. The profile is inserted into the prepared groove in the door frame; the flexibility of EPDM allows easy pressing in without the need for special tools. The cross-section blade, modified in Detail B, then reliably seats against the door leaf and creates a tight seal. After installation, it is enough to occasionally wipe the gasket with a damp cloth – no chemical agents are needed.

Benefits You Will Get

• Perfect insulation – the EPDM profile reliably prevents the ingress of moisture, dust, and pests.
• Long service life – the material resists aging, ozone, and extreme temperatures from -40 °C to +120 °C.
• Precise fit – thanks to Detail B, the profile precisely follows the door frame and requires no additional modifications.
• Low weight – 1.8 kg makes handling easier and does not burden the door structure.
• Versatility – suitable for both shipping and refrigerated containers, regardless of the specific application.

Other Possible Uses

Although the profile is primarily intended for container doors, its properties can be used elsewhere. You can use it for sealing industrial refrigerated boxes, delivery vehicles with thermal insulation bodies, or even for special carpentry constructions where waterproof and dustproof closure is required. Thanks to the flexibility and durability of EPDM, it is a versatile element that can be adapted with a little creativity to various types of doors.
