This TPU-coated water-resistant O zipper is designed for specialty zipper applications where a standard closed-end or separating zipper does not match the shape or access needs of the finished product. It is offered in 17 cm / 6.69 in and 24 cm / 9.45 in lengths, with black N5 nylon teeth, black zipper tape, and a black double-slider combo head.
The O zipper format gives designers more flexibility in products that need an access opening with a non-standard layout. The double-slider construction allows the zipper opening to be adjusted from two points, which can be useful in pet garments, pet carriers, travel bags, organizer compartments, equipment pouches, makeup bags, and specialty textile accessories.
When is an O zipper the right choice?
Select an O zipper when the product pattern needs a specialty zipper path rather than a simple straight closure. It is a practical option for designs where the user may need to open the zipper from different positions or where access needs to be adjusted according to the product’s shape.
For a regular pocket, a simple bag opening, or a short straight compartment, a standard closed-end zipper may be the better option. For jackets and coats that need to separate fully at the bottom, an open-end separating zipper is the appropriate format.
Choosing Between 17 cm / 6.69 in and 24 cm / 9.45 in
The 17 cm / 6.69 in option is suitable for compact pet apparel, small access points, mini bags, and narrow textile constructions. It helps keep the zipper line balanced when the finished product has limited surface space.
The 24 cm / 9.45 in option gives more access room for larger pet garments, carriers, travel organizers, medium-size bags, and broader openings. Measure the zipper path on the actual product pattern before ordering so the zipper can be sewn without unnecessary tension or distortion.
What Does TPU Coating Do?
The TPU coating creates a flexible surface layer that helps reduce direct water exposure along the zipper line. This can be beneficial for products used around rain, splashes, moisture, outdoor conditions, or damp environments.
A TPU-coated zipper alone does not make the finished item completely waterproof. Overall water performance also depends on the outer fabric, seam construction, seam sealing, zipper-end finishing, lining, and the full design of the product. Test a finished sample under real use conditions before approving a production run intended for wet-weather use.
Why Use a Double Slider Combo Head?
This zipper has two sliders. The double-slider combo head arrangement lets the opening be controlled from two points, which can make the product easier to use in specialty patterns and access-focused designs.
To help the sliders operate smoothly, keep fabric away from the teeth during use. Avoid sharply folding the TPU-coated surface or forcing the slider if fabric becomes caught in the zipper chain. Release the trapped material first, then move the slider gradually.
Where Does N5 Work Best?
N5 is suitable for projects that need a more substantial zipper line than a lightweight pocket zipper. It can work well in pet apparel, pet carriers, medium-size bags, travel accessories, technical textile products, and outdoor-oriented accessory designs.
For small wallet compartments, narrow pouches, or very lightweight textile articles, a smaller zipper size may create a more balanced result. For heavy equipment bags or high-load designs, evaluate the zipper construction together with fabric strength, stitch quality, and overall product engineering.
O Zipper, Closed-End Zipper, or Separating Zipper?
Choose an O zipper when the product needs its specialized form and two-point access. For a straight pocket or bag compartment, browse the water-resistant jacket zipper collection to compare closed-end options.
For specialty zipper constructions and alternative forms, you can also review the specialty zipper collection. This helps customers compare the intended zipper shape, closure format, and use case before choosing a finished zipper.
Sewing and Application Notes
When sewing a TPU-coated zipper, avoid pulling the zipper tape into a shape that fights against the product pattern. Plan the zipper line during pattern development and complete a sewn sample before production, especially when the application has a curved or specialty construction.
Secure the zipper ends carefully so the sliders cannot run off the chain during use. Since this model has two sliders, decide their intended resting position before sewing the zipper into the product.
