18 cm T7 Black Nylon Closed-End Pocket Zipper – ENC0018T7

18 cm Black Nylon Coil Zipper for Pocket Sewing

This T7 black nylon pocket zipper is a finished-length sewing component for making zippered pockets or replacing a pocket zipper when the fit and construction match. It measures 18 cm, approximately 7.09 inches. The black tape coordinates with matching fabrics and pocket details.

Closed-End and Non-Separating Construction

The two sides remain joined at the bottom as the slider opens and closes the pocket. This closed-end zipper suits pocket designs that retain a bottom connection. It cannot replace an open-end zipper where a jacket or cardigan front must separate completely. Jacket pockets should be assessed separately for length and installation requirements.

Choosing a Replacement Pocket Zipper

Compare the original zipper's length, end type, coil construction and stitching arrangement. Check the 18 cm length against the pocket opening and allow for the installation's seam allowances. Matching size labels alone do not establish that sliders or other components from different zippers are interchangeable.

Checks Before Completing the Stitching

Position the zipper against the opening and keep the fabric clear of the slider path. Test the opening and closing movement before finishing the stitching. For repeated production, confirm the fit and fabric placement in a sample pocket first.

Sales format: Sold individually as a finished-length zipper, rather than continuous zipper chain sold by the yard or meter.

Frequently Asked Questions

What is a nylon coil zipper?

A nylon coil zipper uses a continuous coil structure to form the interlocking chain. This product is supplied as a finished-length black pocket zipper with a closed-end bottom.

What is a non-separating zipper?

A non-separating zipper stays joined at the bottom when open. It differs from an open-end zipper that allows the two sides to detach completely.

Is this an exact 7-inch zipper?

The specified length is 18 cm, approximately 7.09 inches. Use the metric length when checking the pocket; it should not be treated as an exact whole-inch replacement.

Do I need to replace a stuck pocket zipper?

First check for fabric or loose thread caught in the slider path and avoid forcing it. Damage to the coil, tape or slider may require repair or replacement depending on the fault.

Is this zipper sold by the yard?

No. It is a finished-length 18 cm zipper sold individually. It is not continuous zipper chain.
