Waterproof &
Airtight Zipper

Open-End WaterSeal Zipper

Designed for apparel, providing reliable protection in wet environments.

The single-seal, open-end WaterSeal™ Watertight Zipper is specifically engineered for flexible gear that requires frequent opening and closing while maintaining basic waterproof sealing.Its core feature lies in the single-open-end design.

The TPU-coated zipper teeth create a continuous, impermeable barrier that effectively blocks the intrusion of liquids and moisture when the zipper is closed. This type of zipper balances lightweight design with flexible adaptation, allowing for application on curved surfaces or foldable equipment.
