Dual-Track AeroSeal™ Airtight Zipper
Redundant Sealing for Mission-Critical Applications and Ultimate IPX8+ Protection.
The Dual-Track Aeroseal™ is the ultimate choice for environments where failure is not an option.
Its robust design is built with a redundant set of parallel, interlocking teeth, providing the highest level of security and a hermetic seal. The zipper has been certified with an IPX8+ waterproofing rating, making it a definitive solution for deep-sea diving, hyperbaric chambers, and critical military or HAZMAT containment applications where absolute reliability is paramount.
Key Feature
IPX8+ Redundant Sealing
The dual-track design provides a secondary, backup seal, ensuring unparalleled protection against ingress, even under extreme pressure.
Extreme Pressure Resistance
Maintains hermetic integrity at pressures up to 120kPa, far exceeding the 100kPa industry benchmark for critical applications.
Exceptional Tensile Strength
With a transverse strength of 1673 N, it is over 67% stronger than the standard, built to withstand extreme external forces.
Mission-Critical Durability
Engineered to withstand 1500 reciprocating cycles under load, guaranteeing reliability for equipment where performance is a matter of safety.
