With its robust and flexible design, the multifunctional TIZIP® MasterSeal 6 & 10 offers a high water, air and pressure resistance. The zipper’s plastic teeth are attached to the front and back side of a durable, polyurethane-coated tape. As with the TIZIP® MasterSeal waterproof and pressure-resistant properties are secured by the pressing together of the sealing lip across the interlocking elements. The TIZIP® MasterSeal is opened and closed with a precision metal or polymer metal slider. The zipper’s outstanding properties make it uniquely suitable for a full range of demanding applications. Optional you can add a reinforcement tape on the bottom end, named Q-Strap. The Q-Strap prevents over stressing of the zipper when open.
