A door gasket (also known as a magnetic seal) is the rubber or plastic seal around the door of a refrigerator, freezer or cold room. It ensures that the refrigerated compartment is hermetically sealed. Most door gaskets have a built-in magnetic strip that pulls the door against the frame and simultaneously ensures that the door remains easy to open.

Types of door gaskets
- Push-in profile: door gasket with a push-in barb that clicks into the rebate of the door. The most common type for refrigerators and freezers.
- Flat profile: door gasket with a flap that is screwed, riveted or stapled under a plate or strip.
- Bead profile: similar to a flat profile, with a bead at the end of the flap so that the profile does not shift during installation.
- Hollow profile: door gasket with a flap without a magnetic chamber.
- Rubber profile: door gasket made of rubber or EPDM, for cold rooms, freezer rooms and walk-in coolers.
- Silicone profile: for ovens, steamers and ultra-low freezers.
- Drag seals: seal that drags along the floor to further seal the cooling unit. Especially used in cold or freezer rooms.
- Moosgummi and sponge rubber profiles: soft, sponge-like sealing profiles.
- Glass door and sliding lid profile: For smooth guiding, good gap sealing and controlled damping of sliding lids and glass doors in freezer chests and refrigerated display units.
Replacing a door gasket? Keep this in mind
Are you unsure if your door gasket needs replacing? Look out for these signs:
- The profile has hardened or shows cracks
- The door no longer closes properly or a gap remains visible
- The magnet no longer pulls properly against the frame
A worn door gasket allows cold air to escape from the bottom of the door. This costs energy and can pose a risk to food safety, as the temperature in the cooling unit remains less stable. The refrigeration motor also switches on more frequently, leading to more wear and heat in the room.
Before ordering a new profile:
- Determine the profile type
- Note down the profile code of the current door gasket, so you maintain the same design and fit
- Measure the existing dimensions via dimensions of door gaskets
The right door gasket starts with the right profile
Each profile type has its own installation method and application. Push-in profiles are pressed into the door rebate and can be replaced without tools. Flat, bead, and hollow profiles are screwed, riveted, or stapled. Rubber and silicone profiles are made of a different material and are used in cold rooms, freezer rooms, or specifically for ovens and steamers.

Search by brand
It is possible to search by the brand of the refrigeration unit. View the overview of more than 900 brands. If the brand or type number is not listed, that's no problem. We produce every door gasket to measure. Measure the existing profile, compare the profile code, and use the configurator to set the correct size and color yourself.
Order in a few steps
- Determine the profile: search by brand and type, or by kind, shape and material
- Find an alternative via finding an alternative profile if the original is no longer available
- Measure the correct dimensions, see the explanation of dimensions or watch the instruction video
- Configure material, color and dimensions in the online configurator to see the price directly
- Place your order
We will ship your order quickly. Within 2 to 5 days, it will go with the delivery service. New to DSU? With your first order as a refrigeration company, you will receive a free sample case with frequently used profiles.
A door gasket is the complete seal around the door. The magnetic strip is the component within it that ensures the door is pulled against the frame. Not every door gasket has a magnet; that depends on the profile type.
That depends on the intensity of use and maintenance. As soon as the profile hardens, tears, or the door no longer closes properly, replacement is advisable. A leaking door gasket causes fluctuating temperatures. This is a risk to food safety and can lead to remarks during an NVWA inspection. Additionally, it consumes unnecessary energy.
However, with a push-in profile: you press that into the groove without tools. You replace flat, bead, and hollow profiles with a screwdriver, rivet gun, or staple gun. View our guide or the instructional video for an explanation.
No, you can order from 1 piece, 1 meter, or 1 strip of fixed length.
You can determine the profile in two ways. Search by brand and model of your cooling unit, or determine the profile yourself based on the type, shape, and material. Can't you figure it out? Please contact us, we'll be happy to help you.
