Dual-Slider AeroSeal™ Airtight Zipper
Versatile, Two-Way Access With Certified IPX7 Hermetic Sealing.
Building on the high-performance design of our standard zipper, the Dual-Slider Aeroseal™ introduces the added versatility of a two-way opening.
This zipper achieves a certified IPX7 waterproof rating while also delivering an advanced hermetic seal, offering superior protection against liquids and gases. Its dual-slider configuration allows for convenient access from either end, making it the perfect choice for demanding applications like large enclosures, equipment covers, and medical isolation chambers, where operational flexibility is paramount.
Key Feature
Versatile Two-Way Access
Two sliders provide operational flexibility, allowing the zipper to be opened or closed from either direction or to create a specific opening anywhere along the chain.
Robust IPX7 Airtight Seal
The core zipper chain delivers the same certified protection against liquid and gas ingress as our flagship Standard Aeroseal™.
High-Strength Construction
Built to the same high tensile strength and durability standards, ensuring reliable performance even with frequent use on large applications.
Ideal for Large Openings
Simplifies access to the contents of large bags, tents, and enclosures without needing to fully open the zipper.
