Heavy Duty Zippers

What Are Heavy Duty Zippers?

The heavy duty zippers found here are #8 and #10 gauge zippers, which means the teeth measure approximately 8 millimeters (for a #8) and 10 millimeters (for a #10) across when zipped. They are very large, wide zippers and much sturdier than the medium weight #5 zippers, which are commonly found in retail stores as "heavy duty zippers".

While both #8 and #10 zippers are heavy duty zippers, a #8 is going to be slightly less bulky and less heavy-duty than a #10. 

What Are Heavy Duty Zippers Used For?

Heavy duty zippers and industrial zippers for sewing are designed to replace zippers on coats, work jackets, tents, canvas, sleeping bags, duffel bags, military bags, and other applications that require zippers with extra strength.

When you repair a jacket or bag with a good replacement zipper, you can extend its life and have many more years of use.

What Materials Are Available for Heavy Duty Zippers?

When doing your zipper repair, you'll want to select an appropriate type heavy duty replacement zipper. Choices of zipper teeth include: metal (brass, antique brass, nickel, aluminum), nylon coil, and molded plastic. The strongest metal is nickel, followed by antique brass and brass. Aluminum is a very lightweight metal so when the overall weight of an item needs to be minimized but you still need a heavy-duty zipper, aluminum can be an excellent option. Zippers with molded plastic teeth are often used for boats and other marine uses. Zippers with nylon coil teeth are great for applications that have curves. 

Separating or closed-end heavy duty zipper?

Most of the heavy duty zippers that we are stock are bottom separating zippers, meaning that they can be separated in two pieces (like a zipper on a jacket). If you need a closed-end heavy duty zipper, you can either convert a separating zipper to a closed-end zipper by simply adding a #10 bottom stop to close off the zipper. You can also work with continuous zipper chain to create heavy duty closed-end zippers.
