Elastic Tankpak 6756

Elastic Tankpak 6756 is an excellent gasket for sealing transport containers for chemicals or solvents. The core is made from a hollow elastomeric material (EPDM) wrapped in PTFE foil, thus guaranteeing optimum chemical resistance for the entire seal. The polypropylene middle layer primarily acts as a cushion and buffer, and it is first wrapped with PTFE foil. The entire seal is then over-braided with PTFE yarn, fixing it firmly to the rest of the material composite.

Notes:

For rectangular cross-sections, the maximum width/height ratio should ideally not exceed 3:2. The surface pressure applied to the seal must be evenly distributed around the edge, and must be applied in small increments by attaching as many toggles or clamps as necessary. The sealing surface on the edge of the container or coaming must be smooth and rounded to avoid damaging the seal. The packing may be safely stored in its original packaging for up to 3 years under cool, dry storage conditions.
