YKK Americas Group manufactures airtight and watertight zippers for dive suits, waterproof shoes, survival suits and space suits. Our zippers are watertight, keeping you safe and dry in extreme situations. Our PROSEAL® zippers are UL certified for use in SOLAS suit applications. We are the global leader in keeping closures dry and airtight. Our zippers used in personal flotation devices (“PFDs”) are UL certified to meet the US Coast Guard regulations.
YKK offers varying degrees of water and air resistance zippers. YKK® Airtight/Watertight zippers provide solutions in situations where access is needed, but also where an effective barrier between water, gases, chemicals, liquids, and/or other substances is important. For example, compartments in shipping, aircraft, or civil engineering works, and covers over fermentation vats and water stores are excellent places for a YKK® Airtight/Watertight zipper. Of course, survival suits, including dry suits, firefighter suits, and chemical suits are also ideal candidates for these zippers.
