18 cm / 7.09 in N3 Nylon Coil Pants & Skirt Zipper, Closed End ZPHSN0018T5

This 18 cm / 7.09 in N3 nylon coil pants and skirt zipper is made for garments that need a controlled, fixed-bottom opening. It can be used in pants, skirts, shorts, dresses, light apparel, and similar textile constructions where the zipper should open and close without separating completely at the lower end.

A zipper is one of the parts customers use every time they wear a garment. When the length fits the pattern, the tape color works with the fabric, and the sewing line stays flat, the finished item feels easier to use and more carefully made. A well-matched zipper can improve both the practical function and the perceived quality of pants, skirts, and dresses.

Best Uses for an 18 cm / 7.09 in Closed-End Zipper

This zipper is suitable for pants fly constructions, skirt openings, shorts, dresses, lightweight workwear, and other garments with a fixed-bottom zipper opening. The 18 cm / 7.09 in length can work well in many adult pants patterns, but the actual zipper opening should always be measured before production.

For zipper replacement, measure from the existing top stop to the bottom stop. Check the zipper type, tape width, coil size, color, and sewing line as well as the length. A zipper with the correct length can still be unsuitable if the rest of the construction does not match.

Closed End Means the Bottom Stays Connected

A closed-end zipper has a fixed bottom stop, so the two zipper tapes do not detach completely. This makes it suitable for pants, skirts, dresses, pockets, pouches, and other projects where the lower end must remain joined.

Do not use this type for a coat, jacket, or vest front that needs to open fully at the hem. Those products need an open-end separating zipper with a bottom starter and separator.

N3 Nylon Coil for Light Garment Construction

This product is identified as N3 nylon coil for the U.S. market. It uses nylon coil teeth and polyester tape, creating a flexible fastening line for pants, skirts, shorts, dresses, and light garment projects.

N3 is a useful choice where a heavy molded or metal zipper would look too bulky. For thick denim, workwear, or designs where the teeth should become a visible style element, a metal zipper or larger zipper structure may be a better match.

Choosing Length, Color, and Placement

Confirm the zipper location on the finished pattern before ordering. Consider the waistband, fly extension, seam allowance, lining, hook or button position, and lower end of the opening. These details affect how comfortably the zipper works and how flat the garment sits when closed.

Choose a tape color that either blends with the garment or creates a deliberate contrast. Matching the zipper tape with fabric, lining, closures, labels, and other visible hardware helps the garment look more intentional and more polished.

Sewing Tips for a Cleaner Finish

Align the zipper tapes evenly before stitching. Avoid stretching the tape while sewing because it can create rippling, twisting, or an uneven fly or skirt opening. Test the finished closure before adding final topstitching or waistband work.

For stretch fabrics, lightweight fabrics, lining layers, or thick waistband construction, make a sample first. The zipper should move smoothly, the lower stop should not create unnecessary bulk, and the garment opening should remain flat during normal movement.

When to Choose a Different Zipper Type

Choose an invisible zipper when you want a more discreet closure line for dresses, skirts, and refined fashion products. Choose a metal zipper when a more pronounced denim or workwear hardware look is needed. Choose a separating zipper for jackets and coats that must open completely from the bottom.

For bags, pouches, wallets, and organizers, select the zipper based on the compartment size, tape construction, zipper direction, and expected load rather than choosing only by length.
