Piab DURAFLEX Suction Cups Review: Specs, Price and Applications
DURAFLEX is Piab's suction cup material that blends the softness and elasticity of rubber with the wear resistance of polyurethane. The cups are designed to be strong and flexible at the same time.
The range includes dual-durometer cups with two hardness levels, offering high wear resistance, a better grip that supports production safety and no marks on handled parts.
Quick Verdict
A long-lasting cup material that solves the classic trade-off between soft sealing and hard wear resistance.

Design and Operating Principle
Rubber cups seal well but wear quickly; polyurethane wears slowly but is stiffer. DURAFLEX combines both qualities, so cups last longer without sacrificing sealing.
Dual-durometer cups use a soft lip for sealing and a hard bellow for stability, reducing leakage and improving positional accuracy in fast moves.
Mark-free behaviour matters on visible surfaces such as glass, painted panels or printed packaging.
Integration and Selection
Choose cup geometry for the product and select single or dual durometer depending on surface: dual for uneven or porous, single for smooth.
Expect longer replacement intervals compared with standard rubber cups.
