2384 PIAB Duraflex Dual Durometer 1-1/2 Bellows 75mm PU Vacuum Cup with Fitting

These polyurethane vacuum cups are constructed in two different durometers (hardness). These Duraflex cups have a sturdy and forgiving bellows (60º shore, green) and a large flexible sealing surface (30º shore, yellow) that performs extremely well on uneven surfaces. 30º shore makes these the most flexible sealing surface cups available.

The polyurethane makes them mark free and long lasting. The dual durometer makes these vacuum cups both strong and flexible. Many consider these the best performing polyurethane cup available.
