Dual-Slider AquaSeal™ Waterproof Zipper
Flexible Two-Way Access with Proven IPX5 Water Resistance.
The Dual-Slider Aquaseal™ is designed for waterproof applications that demand flexible access.
By integrating two sliders onto our reliable IPX5-rated zipper chain, this configuration allows users to open large bags, tents, and covers from either end or from the middle. It’s the ideal solution for gear where convenient access is just as crucial as providing complete protection against rain and water spray
Key Feature
Flexible Two-Way Access
Two sliders allow for partial or full opening from either direction, simplifying access to large compartments.
Reliable IPX5 Water Resistance
The TPU-coated chain provides a strong seal against the elements, protecting contents from moisture.
Heavy-Duty Performance
Built to the same high standards of tensile strength and durability as our standard Aquaseal™ zippers.
Ideal for Gear & Covers
Perfect for the main compartments of duffel bags, boat covers, and tent doors where versatile access is needed.
