An airtight zipper functions to protect from water, chemical fumes, and other types of substances. Airtight zippers have been specially designed and manufactured to serve as a form of protective barrier from liquids and gases.

These zippers are also often used in different inflatable objects such as water beds and water-walking balls; protection suits such as decompression clothing, immersion suits, and firefighters’ suits; marine sportswear such as dry or wet living suits as well as life or survival suits; camping gear such as tents and backpacks; and other types of functional clothing.

These airtight zippers are stored individually from the normal zippers because of their special properties and characteristics.

Tips for Using Airtight Zippers

Here are several tips you need to remember when it comes to using airtight zippers:

  1. You need the help of another person to properly and carefully zip the airtight zippers for different clothing items such as dive suits. This is because these are usually placed on the back, which means that the wearer will not be able to access them.
  2. Use water and a soft brush to clean the outer rail of airtight zippers and spread some layer of beeswax on the zipper’s outer rail. But, it is important to take note that beeswax or water must never enter the zipper’s inner rail since this may cause damage to the airtight properties of the zipper.
  3. Avoid pulling harshly if the zippers are tangled by thread or fabric. Pull the zipper head back and slowly remove the stuck cloth or thread before zipping it back again.
  4. It is also not recommended to zip up an airtight zipper fast. Aside from that, it is also necessary not to constantly close or open zippers for a long time or else, the airtight quality of the zipper will get damaged.
  5. Move the head of the zipper pull in a parallel direction down the rack rail. The airtight properties of this type of zipper might get reduced when you pull the zipper pull from a certain angle.
  6. You can also use PVC airtight zippers in a temperature that ranges from 10oC up to 40oC. A temperature that goes beyond these two might end up weakening the bond between the cloth and the zipper and even affect the structural integrity of the zipper since an extreme temperature might lead to some chemical changes in the PVC material.

Tips for Storing Airtight Zippers

Now that you know how to use airtight zippers, here are a few pointers for storing them:

  1. Without an outer packing, garments and clothing that feature airtight zippers must always be hung up when storing them. The zippers should be kept open to prevent the deformation and extension of zippers.
  2. It is also recommended to roll the clothes from the zipper’s end and keep the zipper outside every time you package clothes that feature airtight zippers. These zippers should bent, folded, or pressed by heavy objects.
  3. If you need to store airtight zippers for a long time, use a closed case that can protect it from oxidation and humidity.
