A double-sided (zipper pull on the inside and on the outside) was not available on the market so we had one designed and paid to have a custom mold made for the double-sided zipper pull! This one is incredibly durable!
We are offering a 1 meter long (total length including the ends is 105.4cm or 42.5”) airtight/watertight zipper that is coated with TPU and will bond to vinyl with HH66 or similar vinyl cement. It will also bond with TPU using HH66 vinyl cement as well (TPU and vinyl are compatible materials and will bond very strongly with each other). In fact all of our inflatable suits are made with a TPU zipper that is of the non-airtight variety.
This will NOT bond with latex or rubber. If you need a rubber airtight zipper, you will need to seek a dry suit zipper that is made of rubber.
