Zipper 101: Why and How Do Zippers Split
February 7, 2022

It can happen to anyone—while zipping your backpack, you overfill it, and the zipper splits. Or maybe your jacket zipper is splitting due to wear and tear. You don’t have to get rid of these items if you learn how to repair them. Find out why and how zippers split so that you can figure out how to fix your next broken zipper. 

Reasons Zippers Separate

The fastener on your jacket, backpack, or another item may split for several reasons. There are a variety of causes for zipper failure. The most likely reason is that the slide is loose and unable to close the teeth anymore. Another possibility is that the teeth are out of line and won’t latch together.  

Fix Your Slider With Pliers

A common solution to fixing your zipper is to use pliers to tighten the slide. If your zipper is separating, try pressing the slide together on the chain. Don’t make it so tight that it won’t glide. Make small adjustments until the slide is tight enough to fasten the teeth. 

Realign Your Zipper Teeth

Inspect your zipper for missing or crooked teeth. Use pliers to realign any out-of-place zipper teeth. Once they are straight, try using your zipper again. Continue to align the teeth and remove any threads until the slider glides smoothly.
