What is the purpose of a refrigeration gasket?

A gasket is a piece of rubber that lines the perimeter of a cooler or freezer door creating a seal that keeps cool air from escaping. Door gaskets will eventually start to break down with the constant use and abuse, this leads to gaps in the seal which allows cool air to escape. A poor door seal affects the cooler's performance and efficiency because the cooler requires more power and energy to maintain the temperature.  

What are the main types of gaskets?

There are four types of gaskets. Compression, Magnetic Screw-In, Magnetic Push-In, and Magnetic Dart Mount. We also carry many other varieties of gaskets, if you have questions about our other styles of gaskets please give us a call at 800.695.7929 .

How do I measure a gasket?

Gaskets are always measured outside corner to outside corner. If you are missing a gasket on your unit, you can measure track to track. You must indicate in the notes section on the order page when you are ordering gaskets with track to track measurements. 

Be sure to measure your gasket more than once. We suggest that you measure three times to ensure your measurements are correct. Gaskets tend to be "temperamental" and need to be exact. Gaskets are custom made to order and are not returnable.


How do I install the gasket?

  • Once you have received your new gasket, remove the old gasket and clean the door and dart track with warm soapy water. 
  • Push in/Snap in: Line up the gasket's dart with the dart track on the door and push into place starting with the corners and working to the center of each side. 
  • Screw In: Lift up the old gasket from the inside edge to reveal the screws holding it in place. Remove the screws and back plate that are holding the gasket onto the door. Line new gasket up and start replacing screws closest to the corners and working toward the center. if the gasket begins bunching up behind the retainer panel, loosen the screws and make adjustments. 
  • Doors/ door hinges will sometimes require adjustment before it will close properly with the new gasket. 
  • A heat gun may be used during installation to make the gasket more malleable and therefore easier to install. Using a heat gun at the end of the procedure makes the gasket relax and reduces the risk of gaps and uneven installation. If a heat gun is not available you can also run the gasket through a commercial dishwasher right before installation to make the material more malleable.
