Zippers keep our backpacks closed, our pants up, and turn comforters into sleeping bags.

Where would civilization be without zippers?

Cold, pantless, and fumbling around with buttons in the dark—that’s where.

Have you ever had a jacket or a bag that was ruined because the zipper broke? Once the zipper goes, entire items can be rendered completely useless. The humble zipper really is an amazing invention when you think about it, and its mechanics have pretty much stayed the same after all this time. It’s no wonder why zippers are used on so many things. So what happens when they split? As it turns out, you can totally fix zipper by yourself. but broken zippers are also frustrating little monsters. Without fail, zippers are the first thing to break on a much-beloved jacket. If you’re living with a broken zipper, take heart. You aren’t the only one.

One of the most common zipper malfunctions is a split zipper. You’ve probably had this happen to you with a jacket or coat zipper. Don’t you just hate it when your zipper splits off, especially when you are in a hurry? It’s frustrating isn’t it? After zipping your jacket, the zipper separates or splits open. Most people think that a split zipper must be replaced, but that is not always the case. You can fix split or separating zippers many times without doing any sewing at all.

What causes zipper to split

Often the problem is not with the zipper, but with the zipper slide. the zipper slide is the metal piece that slides up and down the zipper. the zipper slide can stretch out of shape with use. to fix the zipper and prevent it from separating, you may be able to tighten up the zipper slide by pinching it ever so slightly with a pair of pliers.

Few tips on how to fix a split zipper

This is an easy way to fix a zipper without replacing it. This method is really fast too. It works when the zipper pull doesn’t close the zipper together anymore. You can save a jacket, a tent, a sleeping bag, and many other items.

Check the zipper

First, double-check to make sure a piece of cloth or thread isn’t stuck in the zipper.

Straighten bent teeth

You may need to fix bent teeth to get your zipper to close. to do this, use your tool of choice (perhaps pliers) to pull the tooth straight.

1) Repeat as needed.
2) Be careful not to pull the tooth out of the tape.
3) Test the repair by opening and closing the zipper as normal.

Remove buildup from a zipper’s teeth

When substances build up around the teeth of your zipper, it can prevent the zipper from staying closed. As a result, you’ll need to clean the teeth and remove stuff that could be preventing the zipper from closing.

1) Combine water and soap in a small dish, and stir until suds form.
2) Dip a clean rag in the soapy water and wipe down the zipper’s teeth.
3) Grab a fresh rag and run it under the tap.
4) Wipe the soapy mixture off the teeth with the damp rag.
5) Attempt to zip and unzip as normal.

Fix the slider

If the teeth are straight, and clean, take a look at the slider itself. Over time, the slider starts to come apart, and when that happens, it stops clinching the zipper teeth together. Follow these steps;

Step 1: what you’ll need
You will only need a pair of pliers.
But if the slider is really destroyed or is made of plastic you will need a new one of the same size. you can find it in another old jacket. Or you can buy one online for really cheap.

Step 2: remove teeth
remove the little iron teeth of the top of the zipper, which will be on the same side of the jacket where the slider is.

Step 3: remove slider
remove zipper pull. You can probably see that it is all distorted.

Step 4: Adjust the slider (Only for iron zippers)
with the pliers close the two sides of the zipper pull, try to make it look like the original shape again. If your zipper pull is not too worn out you can try to close it directly on the zipper, without removing it.

Step 5: Put back the slider
Put back the slider. It may take a little bit of time.

Step 6: Put back the tooth
Put back the iron tooth with the pliers.

If the zip still splits, replace the slider when replacing the slider, make sure to:

• locate the side of the zipper that has the square tab on the bottom.
• wedge the top teeth of the zipper into the slider.
• If necessary, use a flathead screwdriver to wedge the teeth into the gap.
• wiggle and pull the slider until it moves down to the bottom of the zipper.

As for jeans, the solution is a little more complicated. If you can, you need to remove the metal bumper at the bottom and replace it with stitches, or just tie it off in the middle if teeth are missing at the bottom. Unfortunately, this only really works with pants where you can actually get to the bottom bumper.

If that fails, or you’re working with pants where you can’t get to the entire zipper run, you might need to replace the zipper completely.
