Our newly developed TIZIP® MasterSeal Ocean10 is based on the same mechanical principle as the TIZIP® MasterSeal 10 but offers greater resistance to hydrolysis and microbial action. The zipper’s plastic teeth are attached to a durable, polyurethane-coated tape. When the plastic slider interlocks the zipper’s teeth, a sealing lip gives the zippered seam its unique waterproof and pressure-resistant properties. The TIZIP® MasterSeal O10 was specially developed for watersports such as scuba. A reinforcement tape on the bottom end, named Q-Strap, prevents over stressing of the zipper when open. The TIZIP® MasterSeal O10 is currently available only in our standard lengths.
