The sealing gum (or door seal) is a part on which 30% of the efficiency of the refrigerator depends. If it is worn out, no longer fits tightly or becomes cracked, the compressor begins to wear out and electricity is wasted. But before buying a new seal, you need accurately measure the old one, otherwise you risk getting an elastic band that will not fit in length, width or profile.
Many people mistakenly think that it is enough to simply attach a ruler to rubber band - in fact, you need to take into account profile geometrythe radius of curvature and even the brand of the refrigerator. In this article we will analyze three professional measuring methods (including a template method for complex cases), tell you how to avoid common mistakes, and give a table of standard sizes for popular brands - from Indesit to Liebherr.
If you have never repaired equipment, don’t worry: the process is no more complicated than replacing the brushes in a vacuum cleaner. The main thing is not to rush and follow the instructions. And if the refrigerator is still under warranty, check the conditions of the service center: some manufacturers (for example, Bosch) will void the warranty if you independently interfere with the door design.
1. Preparation: tools and conditions for accurate measurements
Before grabbing the tape measure, make sure that the refrigerator door completely defrosted is closed for at least 2 hours. This is important because at low temperatures the rubber shrinks, and after thawing it can stretch a little - a difference of 2-3 mm is already critical for a tight fit.
You will need:
- 📏 Flexible tailor's tape measure (metal or plastic a ruler will not work - it does not follow the curves).
- 📄 A sheet of A4 paper and a pencil (to create a template).
- 🔍 Magnifying glass or flashlight (to examine the markings on the seal).
- 📐 Square (to check right angles door).
- 📱 A smartphone with a camera (for fixing the rubber profile).
If the seal is glued to the door and not inserted into the groove, additionally prepare solvent for glue (for example, White spirit) and a plastic spatula. Do not use a knife or metal tools - they can damage the plastic door panel, which will lead to corrosion or cracks.
⚠️ Attention: If the refrigerator is connected to the system No Frost, before taking measurements, disconnect it from the network for 10–15 minutes. Fans in such models can create vibrations that distort the results.
2. Method 1: Linear measurement along the perimeter of the door
This is the simplest method, but it is only suitable for refrigerators with with a rectangular seal (without complex bends). Algorithm:
- Open the door and fix it in a horizontal position (you can place a book).
- Attach a tape measure to inner edge of the seal (where the elastic comes into contact with body).
- Measure the length along the entire perimeter, starting from the top corner. Important: do not tighten the tape measure, but also do not leave any slack.
- Write down the result to the nearest millimeter.
For two-chamber refrigerators (for example, Atlant MXM-1708 or Samsung RB30J3000WW), measurements must be taken separately for the refrigerator and freezer cameras Please note that the seals in them may differ in width!
| Brand | Model (example) | Standard seal length (mm) | Profile type |
|---|---|---|---|
| Indesit | C 132 G | 1180 × 540 | Rectangular with magnet |
| Atlant | MHM 1706-03 | 1200 × 560 (top/bottom) 580 × 560 (sidewalls) |
With rounded corners |
| LG | GA-B409SEGL | 1150 × 530 | Two-lobe |
| Samsung | RB29FERNCSS | 1190 × 550 | With an additional groove |
If your model is not listed in the table, do not panic: most seals are universal. The main thing is a match in length and profile type (more on this below).
Compare the length around the perimeter (±5 mm)

3. Method 2: Template measurement (for complex profiles)
If the seal has a non-standard shape (for example, with protrusions for attaching shelves or rounded corners), linear measurement will not be enough. In this case, use a paper template:
- Take a sheet of paper and attach it to the seal.
- Carefully trace the outline with a pencil, repeating all the bends. For accuracy, use short pieces (5–10 cm).
- Cut the template along the contour with scissors.
- Attach it to a new seal in the store or compare it with the drawings on the manufacturer's website.
This method is especially useful for premium refrigerators (for example, Liebherr CNef 4815 or Beko GNE114620X), where the seals have a unique geometry. If you are not sure of the accuracy, make templates for the all four sides door separately.
How to trace the corners without errors?
When tracing the corners, do not turn the sheet of paper - draw the line smoothly, slightly going beyond the edge. After cutting out the template, carefully adjust the corners to 45° with scissors. To check, attach the template to the seal: if there are gaps in the corners of more than 1 mm, repeat the outline.
Some seals (for example, in models Whirlpool) have asymmetric profile one side wider than the other. In this case, mark the installation direction with an arrow on the template (usually indicated on the seal itself with letters TOP or BOTTOM).
4. Method 3: Photographic measurement (for remote purchase)
If you order the seal online (for example, at AliExpress or in specialized stores), it is impossible to send the exact template. In this case:
- Take a photo of the seal from a distance of 30–40 cm, placing a ruler or tape measure next to it for scale.
- Take separate pictures:
- 📸 General view of the door (to show the location of the seal).
- 📸 Cross section of the elastic band (to determine the profile).
- 📸 Door angle (to show the docking).
- 🔢 Brand and model of the refrigerator.
- 📏 Dimensions around the perimeter (from method 1).
- 🔍 Type of fastening (groove, glue, screws).
Example of correct description for order:
Refrigerator: Samsung RL34ECMS, 2019Seal: top/bottom - 1190 mm, sides - 550 mm.
Profile: two-lobe with magnet (photo 2).
Fastening: groove + 2 screws at the bottom (photo 3).
⚠️ Attention: The seal is often not visible in the photographs. magnetic insertIf it is in the original, check with the seller for its availability - without a magnet the door will not close hermetically.
5. How to determine the type of seal profile?
A profile is the cross-sectional shape of an elastic band. It depends on whether the seal will fit your model. There are 5 main types:
- 🟥 Rectangular —the simplest, suitable for most budget models (Biryusa, Position).
- 🟨 Double-lobe —with two “lips” for better tightness (often data-i="161">i LG And Samsung).
- 🟩 With a groove for a magnet — the magnetic insert is hidden inside the elastic band (for example, in Bosch KAN92VI30R).
- 🟦 With rounded edges — for designer models (for example, Smeg FAB28).
- 🟪 Universal - suitable for several brands, but requires adjustment.
To determine the profile, do cross section of the seal (you can use a knife if the elastic is already faulty) or shine it with a flashlight on the side - the shadow will show the shape. Compare with the diagram:
Some seals have markings - for example, TPE-12 or EPDM-8. This designation of material and rigidity:
TPE- thermoplastic elastomer (soft, durable).EPDM—ethylene-propylene rubber (resistant to temperatures from -50° to +130°).PVC—polyvinyl chloride (cheap, but cracks in the cold).
6. Typical errors when measuring and how to avoid them
Even experienced craftsmen sometimes make mistakes. Here are the most common mistakes and ways to prevent them:
- Measure along the outer edge of the seal (not on the inside). This gives an error of up to 10-15 mm, since the elastic band can protrude beyond the door.
⚠️ Attention: The outer edge of the seal is often deformed over time, so you cannot use it as a guide.
- Ignoring corners. In refrigerators Side-by-Side (for example, Haier A3FE742CGMJ) the corners of the seal may be beveled. If this is not taken into account, the new seal will not work. will lie flat.
- Purchase by model refrigerator without checking. Even from the same manufacturer, seals may differ. For example, Indesit BIAA 13 and Indesit BIAA 13 F have different rubber bands due to door modifications.
- Not taking into account the method of fastening. The seal can be attached:
- 🔳 In the groove (the most reliable option).
- 🧲 On magnets (requires an exact match polarity).
- 🛠️ On screws or glue (you need to clean the surface).
If you doubt your measurements, use online calculators (for example, on the websites Spare parts for refrigerators or All-Spares). It is enough to enter the model of the equipment, and the system will select compatible seals. However automatic pickers do not take into account door wear - if it is sagging, the standard seal may not work. approach.
7. Where to buy a seal: prices and trusted suppliers
The cost of the seal depends on the brand, material and profile complexity. Average prices in 2026:
| Sealant type | Price (RUB) | Where to buy | Delivery time |
|---|---|---|---|
| Universal (PVC) | 800–1 500 | Ozone, Wildberries | 2–5 days |
| Original (EPDM, for Samsung/LG) | 2 500–4 000 | Official service centers | 1–3 weeks |
| For built-in refrigerators | 3 000–6 000 | Specialized stores (All-Spares) | 7–14 days |
| Magnetic (with insert) | 1 800–3 500 | AliExpress, eBay | 20–40 days |
Before purchasing, check:
- 📦 Availability of warranty (at least 3 months).
- 📄 Certificate of conformity (the seal must be food grade, without toxic additives).
- 🔄 Possibility of exchange (if the size is not suitable).
If you are looking for a seal for a rare model (for example, Zanussi ZRB38200WA), try ordering it through eBay or Amazon - they often sell used parts from disassembled equipment in good condition.
FAQ: Frequently asked questions about measurements seal
Can I use a seal from another refrigerator model?
Yes, if they match:
- Perimeter length (±5 mm).
- Profile type (for example, two-lobe).
- Method of fastening (groove/adhesive/magnet).
However, keep in mind that universal seals may hold the cold worse, since they are not designed for a specific door geometry.
How to understand that it is time to change the seal?
Symptoms wear:
- 🔍 Visible cracks or tears.
- 💨 The door does not stay closed (opens with a slight push).
- ❄️ Frost on the back wall (due to warm air entering).
- 🔊 Extraneous noise (the compressor works without stopping).
You can check the tightness using test with a sheet. paper: close the door, holding the sheet between the seal and the body. If the sheet is easily pulled out, the rubber is faulty.
Is it necessary to disassemble the door for measurements?
No, in 90% of cases an external inspection is sufficient. Disassembly is required only if:
- The seal is glued and cannot be removed without damage.
- The door has hidden fasteners (for example, in models Liebherr).
For disassembly you will need a screwdriver and a plastic pick (so as not to scratch the panel).
What to do if the new seal is longer than the original?
If the difference is up to 10 mm, you can carefully trim the elastic in the corners at 45° and glue joints superglue for rubber (for example, Loctite 406). If the difference is greater, return the seal to the seller: it does not fit.
Do not try to stretch the elastic - this will lead to tears when closing. doors.
How to care for the seal so that it lasts longer?
The service life of the seal is 5–10 years, but with proper care it can be extended:
- 🧼 Once a month, wash the rubber band with warm water and soap (without abrasives!).
- 🧴 Lubricate with silicone grease (for example, WD-40 Specialist) 2 times a year.
- ❄️ Do not allow the door to ice up - ice deforms the seal.
- 🚪 Do not slam the door or hang heavy objects on it.
