Piab DURAFLEX RB20x40P Rectangular Suction Cup Review: Specs, Price and Applications
The Piab RB20x40P is a rectangular DURAFLEX suction cup in a 20 x 40 format, developed for handling flow-packed bars of sweets and other small rectangular flow-pack packages.
It has a single bellows with a low overall height for tight spaces, a relatively firm lip that avoids being sucked into the cup, and two alternative fittings for correct orientation. DURAFLEX combines rubber-like elasticity with polyurethane-like wear resistance.
Quick Verdict
A precise match for flow-pack bars, where round cups waste area and soft lips wrinkle thin film.

Design and Operating Principle
Bars are long and narrow, so a rectangular cup covers more of the surface than a round one of the same width, giving more holding force and stability.
Flow-pack film is thin and flexible; a firm lip prevents it being drawn in, which would wrinkle the pack and leak.
Two fitting options ensure the cup aligns with the product orientation on the gripper.
Integration and Selection
Use in flow-pack machines and pick-and-place of bars. Choose the fitting that matches the gripper's orientation.
Low height suits compact pick heads.
