Waterproof Duffels
Key sealing challenges
- Long-term exposure to fresh or salt water.
- Continuous stretching and bending close to the body.
- Comfort requirements for tight-fitting suits.
- In some cases, dry inside .conditions even under immersion.
Recommended zipper solutions
Choose AquaSeal™ for surface water sports; consider AeroSeal™ where true dry conditions and airtightness are required.
- AquaSeal™:wetsuits, semi-dry suits, surface sports gear.
- AeroSeal™: drysuits and systems that must stay dry inside.
- Configurations for back zips, front zips and relief zippers.
HAZMAT & medical containment
Designed for airtight containment, chemical resistance and infection control.
Key sealing challenges
- Risk of chemical/biological aerosol/infectious liquid leakage.
- The requirements of positive/negative pressure
systems on sealing continuity. - Mechanical wear from frequent putting on and taking off, as well as during the cleaning process.
- The effect of different disinfectants (chlorine, alcohol,peroxide) on materials.
Recommended zipper solutions
- Level A & high-risk Level B protective suits used in chemical response,biological containment and CBRN environments.
- Medical isolation chambers, patient transport pods,quarantine enclosures and inflatable decontamination tunnels.
- for welded integration into isolation chambers,transport pods and inflatable decontamination tunnels.
Fully encapsulated HAZMAT suits
Decontamination suits and response gear
Surgical and isolation gowns with high sealing requirements
CBRN Protective Garments
Applications in the field
These examples illustrate how different industries use ZIZIP™ waterproof and airtight zippers in real products. You can adapt similar concepts to your own projects.
AeroSeal™ airtight zippers help maintain hermetic protection in hazardous decontamination operations.
Carefully integrated airtight zippers support controlled access and reliable sealing around patients.
Zippers are placed where movement and sealing demands intersect, balancing comfort and protection.
Long AquaSeal™ zippers provide wide openings for packing while keeping gear dry in harsh weather.
AeroSeal™ zippers help manage access while maintaining the airtight shell of the structure.
Tailored zipper paths create service access points in protective covers for machinery and marine systems.
How we support your application
We work as a sealing partner, not just a zipper supplier. Our process connects application requirements with the right technical solution and reliable manufacturing.
We begin by defining your application requirements, including the sealed medium, operating pressure, target IP or airtightness level, service life, and applicable standards. This ensures clear alignment across engineering, sourcing and quality teams.
Our engineers recommend AquaSeal™ vs AeroSeal™, sizes (#3 / #5 / #8), slider and puller configurations, and integration methods (sewing, welding, lamination) based on your design envelope and end-use environment.
We support prototypes, test samples and design iterations until sealing performance, ergonomics and durability meet your internal and external test criteria. This can include lab tests, field trials and joint reviews of failure modes.
Once the design is validated, our vertically integrated production and quality systems help stabilize performance, lead times and supply for your program – from initial ramp-up through mature volume production.
