1769 Aclathane 2-1/2 Bellows 30mm Vacuum Cup

These polyurethane hybrid cups are an excellent value. These cups get 6X more life than silicone and 2X more life than other polyurethane cups. Yet the price premium is only about 1.3X more than other polyurethane cups. The maximum temperature threshold is slightly higher than other PU cups. They are non-marking and contain no silicone so they are suitable to be used with parts that will be painted. With a shore rating of 72°, ACLA-PU is a little stiffer than silicone and some other polyurethanes, so keep this in mind if your part is textured or deeply contoured.
