Plastic Open End Zips

Browse our range of plastic open-end zips — also known as separating zips — stocked across 16 colours and 11 lengths from 10 to 30 inches. All zips in this collection feature moulded Delrin or Acetal teeth for a smooth, reliable action that holds up to regular use.

Open-end zips fully separate at the base, making them the correct choice for jackets, hoodies, gilets, and any garment that needs to open completely. The plastic moulded construction is lightweight, corrosion-resistant, and suitable for both hand and machine sewing.

All stock is held in Birmingham and available for same-day dispatch on orders placed before the daily cut-off.

What Are Open-End Zips?

An open-end zip (also called a separating zip) has a box and pin at the base that allows the two sides to fully detach. This is the standard construction used in jackets, coats, and hoodies. Closed-end zips, by contrast, are fixed at the bottom and used in trousers, bags, and cushions.

Suitable For

Jackets, hoodies, gilets, fleeces, sportswear, children's clothing, craft projects, and garment repairs requiring a full-separation fastener.

    109 in stock Express UK Shipping Available  

    A genuine YKK Vislon No.8 open-end jacket zip with moulded plastic teeth — available in 14 colours and three lengths, made in the UK. Brand: YKK Range: Vislon Material: Moulded plastic teeth, 35mm woven tape Gauge: No.8 (8mm tooth width) Type: Open end (separating) Lengths: 18 inch (46cm) · 20 inch (51cm) · 22 inch (56cm) Colours: Black · Navy · Royal Blue · Brown · Ivory · Light Ecru · Fawn · Khaki · Forest Green · Dark Grey · Burgundy · Red · Dark Wine · White Pack size: Sold individually (1 zip per order) HS Code: 9607110000 Country of Origin: United Kingdom The YKK Vislon No.8 is the standard open-end zip for outerwear, workwear, and performance clothing. The No.8 gauge means 8mm teeth — substantially larger than the No.5 used in most everyday garments — giving a stronger, more reliable fastening. Vislon moulded plastic teeth have a distinctive chunky appearance and a smooth, positive action that holds up to repeated use. The wide 35mm tape is well suited to heavier fabrics where a secure seam allowance matters. With 14 colours and three lengths, this is a practical stock zip for garment makers and repair specialists alike. How to Order: Select your preferred Colour from the dropdown (14 options available). Select your required Length — 18 inch, 20 inch, or 22 inch. Add to basket and proceed to checkout. Colours may appear slightly different depending on your monitor settings and lighting conditions. Note: colour 578 (Dark Grey) appears closer to a mid-grey tone in real-world lighting. If colour matching is critical, we recommend ordering a sample first.

At 8mm, the No.8 gauge teeth are substantially larger than the No.5 found in most everyday garments, delivering a stronger, more positive fastening that stands up to repeated daily use. The open-end construction means the zip separates fully at the base — the standard requirement for any garment that opens completely. The wide 35mm tape provides a generous seam allowance, ideal for stitching securely into heavier coat and parka fabrics. How to Order: Select your preferred Colour from the dropdown (14 options available). Select your required Length — 24, 26, 28, 30, or 32 inch. Add to basket and proceed to checkout.
