A 27-inch separating zipper can replace a coat or jacket zipper when its teeth length matches the original. The WAVEBEEXS three-piece set is best for general repairs, while ANPURZII and YZSFIRM offer two-piece black #5 plastic options. Choose MebuZip’s #8 metal zipper for a heavier-duty metal option, or Deoward for a two-piece set with right-hand orientation specified. Before buying, confirm zipper size, opening direction, color, and whether 27 inches refers to the teeth or the full zipper.
| Product | Best for | Key detail |
|---|---|---|
| WAVEBEEXS #5 | General sewing and repairs | Three-piece set |
| ANPURZII #5 | Left-hand replacement | Two black zippers |
| YZSFIRM #5 | Bulk black replacements | Two-piece set |
| MebuZip #8 metal | Metal zipper preference | Right-hand, one piece |
| Deoward #5 | Right-hand plastic replacement | Two-piece set |
WAVEBEEXS #5 Three-Piece Jacket Zipper Set

This set is best for home sewers who want multiple black zippers for coat, jacket, sweatshirt, or other sewing projects. It includes three #5 separating zippers made with resin teeth and polyester fabric tape. The listed features describe broad use for garments, tents, and craft projects.
The manufacturer states that the zipper was tested for more than 30,000 sliding cycles. That makes it a practical option for shoppers prioritizing a stated durability test. Limitation: The product details do not specify left- or right-hand orientation, so check that the zipper opens on the correct side for the garment before ordering.
ANPURZII #5 Two-Piece Left-Hand Set

Choose this two-pack if the garment requires a left-hand zipper and you want black plastic replacement zippers. The listing specifies a 27-inch teeth length and a 28-inch end-to-end length. Its molded plastic construction is described as sturdy and wear-resistant, with a smooth pull.
This is a better fit than products without a stated opening orientation when left-hand configuration is required. It is intended for sewing coats and jackets, among other uses. Limitation: Do not assume it will suit a right-hand zipper installation; verify the original zipper’s orientation before purchasing.
YZSFIRM #5 Two-Pack Black Separating Zippers

YZSFIRM is best for buyers seeking two black #5 resin zippers for sewing or replacement work. The stated teeth length is 27 inches, while the total end-to-end length is 28 inches. The listing names jackets, coats, bags, purses, sweatshirts, upholstery, tents, and other projects as possible uses.
Choose this set when you need a simple two-piece supply of black plastic zippers rather than a mixed-color assortment. The product details describe the zippers as sturdy and durable. Limitation: The listing does not identify the zipper’s hand direction, so confirm compatibility with the garment’s opening arrangement.
MebuZip #8 Right-Hand Metal Zipper

This zipper is best for shoppers who specifically need a heavier #8 metal zipper rather than a standard #5 plastic option. It has black nickel teeth, a right-hand orientation, and a listed 27-inch teeth length with a 28-inch overall length. The product information describes brass teeth and a metal pull for winter coats, hoodies, and leather jackets.
Choose it when the original garment uses a compatible metal zipper and the stated right-hand orientation matches. Limitation: It is sold as one zipper, and #8 is a different size from #5. Do not select it as a direct replacement unless the garment’s zipper size and construction match.
Deoward #5 Right-Hand Two-Piece Set

Deoward is best for buyers who want two black #5 plastic zippers with right-hand orientation specified. The listed teeth length is about 27 inches, and the overall length is about 28 inches. Its resin teeth and reinforced polyester tape are described as durable, and the pull has a PU leather wrap for grip.
The listing also describes smooth opening and closing. This set is a useful comparison choice when orientation matters and a two-piece quantity is preferred. Limitation: The listed length is approximate, so measure the original zipper’s teeth before ordering, especially when an exact fit is important.
Buying Guide: How To Choose A 27-Inch Separating Zipper
Does 27 inches mean the full zipper length?
Often, no. Several products here specify 27 inches for the teeth and about 28 inches from end to end. Measure the closed zipper’s teeth from the bottom insertion area to the top stop, then compare that measurement with the product listing. Do not rely only on the overall tape length.
Should you choose #5 or #8?
Match the size of the replacement to the original zipper. The featured plastic options are #5, while the MebuZip metal option is #8. These sizes are not interchangeable by default. Compare the teeth size and zipper construction on the garment before choosing a replacement.
Does zipper direction matter?
Yes. Left-hand and right-hand zippers open in different orientations. ANPURZII specifies left-hand, and Deoward and MebuZip specify right-hand. For listings that do not state the direction, inspect the original zipper and confirm the replacement’s orientation before buying.
Which material is the better fit?
Plastic or resin zippers suit shoppers looking for the listed #5 options for jackets, coats, and craft projects. The metal MebuZip is a different choice for a garment that originally uses a compatible #8 metal zipper. Prioritize matching the original instead of choosing by material alone.
How many zippers should you buy?
A single replacement may be enough for one repair, while two- or three-piece sets provide spares for future sewing. Check the package quantity and color. Mixed-color options may be useful for varied projects, but the products selected here focus on black replacements.
Frequently Asked Questions
What is a separating zipper?
A separating zipper opens fully into two halves, as commonly needed for jackets and coats.
Can I replace a 27-inch zipper with a 28-inch one?
Some listings describe a 27-inch teeth length and 28-inch total length. Compare the teeth measurement, not just the overall length.
Are all 27-inch jacket zippers the same size?
No. They can differ in zipper size, material, hand direction, color, and whether the stated length measures the teeth or full zipper.
What does #5 mean on a zipper listing?
#5 identifies a zipper size category. Match it to the original zipper rather than assuming any 27-inch zipper will fit.
Which option is explicitly right-hand?
Deoward’s #5 plastic set and MebuZip’s #8 metal zipper are listed as right-hand options. Confirm the size and material requirements as well.
