SZIP Metalproof Sealed Waterproof Metal Zipper(8TZ CR Airtight Zipper & Waterproof Zipper), which is also called water tight and air tight zipper, consists of two fabric tapes.

The ends are sealed by the chloroprene rubber that is formed by vulcanization molding. The part of fabric tape is made by coating the polyester fabric with chloroprene rubber.

The inner teeth are fixed on the outer teeth through the fabric tape. When the slider closes up the two fabric tapes, the fabric tape with elasticity between the outer teeth will be compressed into the shape, as shown in the figure, and the double sealing status will be formed.

Therefore, the zipper can provide protection against the water, dust, air, sunshine, etc. when it is completely closed. Even if it is exposed to certain pressure and bending, the zipper can still keep the abovementioned sealing property.
