Introduction

Broken zipper ruin your favorite clothing? Don’t throw it away just yet! The most common issue with zippers is a broken or missing insertion pin, the part of the zipper that goes inside the other. While there are zipper-repair kits sold at Walmart, they commonly do not last due to the amount of stress the insertion pin receives in daily use. The best way to replace the pin is to sew in a new one, including the fabric and plastic backing surrounding it. No kit required— just some scissors, needle, and thread!

    • Cut the broken insertion pin off the zipper. If the pin is missing (like in the photo), cut the frayed fabric. Do not cut the zipper teeth.

    • Find an article of clothing no longer in use with a zipper. The insertion pin must be the same length as the broken/ missing one, but it does not matter if it is plastic or metal.

    • Cut the working insertion pin from the old clothing off the zipper. Do not cut the plastic square backing or too much material. You must have enough fabric to sew.

    • Line up the new insertion pin on the broken coat.

    I appreciate this video. I've gone to several alteration shops and they want to replace the entire zipper. Pretty silly in my opinion. But, they're the professional seamstresses. I will learn to sew today..

    Are there pins available to purchase for a plastic zipper (probably size 8 )somewhere with instructions. Can a pin be removed & recrimped? I have an expensive jacket with 2 sliders. Problem is a tooth on plastic coil zip is out of place a/b 1 inch above the pin. Can I remove the existing pins & move them up?

If the pin does not line up correctly, take out the thread and re-sew.

Hi, I have a north face jacket and the zipper is fine but the plastic square backing is what’s missing so I can’t zip it up. Do you know what that’s really called so I can find a replacement? Or do you know what I can replace it with? Thanks, Amy

Instead of cutting a notch out, I removed the stitching at the edge of the coat to expose the entire zipper body end, and completely cut the end off. Then I stitched a complete new end on. The advantage was that it provided the maximum mechanical strength to keep the insertion pin aligned.

Careful when at the cut lines, do not pull on any threads, some are loose, but I have a way to fix that later. Then stitch using long stiches to avoid the areas too close to the cut lines where the threads are loose.

Finally, I zip the 2 halves together in order to align all the parts together into their final relative positions, and use a Bondic glue pen on all stitches and areas around the cuts where the loose threads are. When I cure with the UV light, the result is much stronger than just the threads. I was careful to not apply any of the epoxy close to the zipper, so that I don’t block the passage of the zipper slider.

Then I lightly sand to remove any sharp edges, and sew the zipper tape back to the jacket.

I will need to see a YouTube video on that lol

That’s a great solution. I considered that, but it seemed like way more work, so I opted for a simpler fix. You could also replace the entire zipper if you wanted!

Hello:

I have a question. I own an LL BEAN winter jacket. The zipper doesn't work. It seems I need a Bottom Stop, an Insertion Pin, and a Retainer Stop. On the back of the slider, it says:

YKK

5VSt

VISLON

Can you help me? I have a photo, if needed.

Thank you,

David

Hi, David!

I’m certainly no expert, but can you include the photo? Maybe I’ll be able to help.

All you have to do is go to amazon, or wherever and put in the type of zipper that you mentioned above. If replacing the whole thing, you need to know how many inches it is. If you’re just replacing the bottom pieces mentioned, it doesn’t matter how long it is.

I just need to replace the pin on a child’s zip hoodie. I don’t have any used jacket to cut the pin out. I suppose I can buy a replacement zipper and just cut the pin+material from the replacement zipper and sew it on. However, is there a size difference in zipper pins/boxes for children’s clothing? I see a number on the original zipper box…N3P. Is this the zipper size or number that I need to match?

I need to replace an insertion pin on a coat that zips open from both ends. What tools and parts do I need to do that?

Hello

Thank you very much for your great tip. Now I go to the attic and search through my bags of clothes that are still stored there, which I still haven't sorted out since I moved here.
