YKK Vislon Heavy Two Way Open End Plastic Zip 8 Weight 6 Colours 4 Sizes

68 in stock Express UK Shipping Available

A genuine YKK Vislon #8 heavy-duty two-way open-end plastic zip — chunky 7mm moulded teeth with a moveable bottom stop, in 6 colours and 4 lengths. Brand: YKK Range: Vislon Heavy (#8) Material: Moulded plastic (Vislon) teeth, 35mm woven tape Tooth width: 7mm Tape width: 35mm Type: Two-way open end (separating, opens from top and bottom) Lengths: 24 inch (61cm) · 26 inch (66cm) · 28 inch (71cm) · 30 inch (76cm) Colours: Black · Brown · Fawn · Navy · Dark Grey · Khaki Pack size: Sold individually (1 zip per order) HS Code: 9607200000 Country of Origin: Please verify with supplier The YKK Vislon Heavy is one of the chunkiest plastic zips in the YKK range. The #8 gauge gives you a 7mm tooth that feels substantial in the hand and handles the stress of outerwear, bags, and technical garments without snag or flex. The two-way construction means it can be opened from both the top and the bottom — useful on longer coats for seated movement, or on bag designs where access from below matters. The Vislon moulded tooth is smoother-running than a metal tooth and holds its shape well under repeated use. Please note: the Dark Grey colourway is closer to mid-grey in person — refer to the product images carefully if colour matching is critical. How to Order: Select your preferred Colour from the dropdown (6 options available). Select your required Length — 24, 26, 28, or 30 inch. Add to basket and proceed to checkout. Colours may appear slightly different depending on your monitor settings and lighting conditions. Please note the Dark Grey variant is closer to mid-grey in person — if colour matching is critical, we recommend ordering a sample first.

YKK Vislon No.8 Heavy Duty Open End Coat Zip 14 Colours 24 26 28 30 32 Inch

1 review

162 in stock Express UK Shipping Available

A genuine YKK Vislon No.8 open-end coat zip with chunky moulded plastic teeth — available in 14 colours and five long 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: 24 inch (61cm) · 26 inch (66cm) · 28 inch (71cm) · 30 inch (76cm) · 32 inch (81cm) 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 go-to heavy-duty open-end zip for full-length coats, long parkas, maxi outerwear, and performance garments where a shorter jacket zip simply won't reach. 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. 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.
