SMC ZPT13BFK10-04-A10 | ZP Series Basic Bellows Vacuum Pad 13mm Vertical Inlet With Buffer FKM Fluoroelastomer 10mm Stroke Chemical Resistant

The SMC ZPT13BFK10-04-A10 is a bellows type vacuum pad from the ZP series, featuring a 13mm pad diameter with FKM (fluoroelastomer) rubber construction, vertical vacuum inlet, and 10mm buffer stroke. The FKM material designation ("F") makes this the chemical-resistant specialist of the ZPT lineup, engineered for vacuum handling applications where exposure to aggressive chemicals, solvents, acids, or petroleum-based fluids would rapidly degrade standard NBR or urethane pads.

When is FKM the right pad material choice? FKM (also known as Viton® or fluoro rubber) provides outstanding resistance to a wide range of chemicals including mineral oils, fuels, hydraulic fluids, aromatic hydrocarbons, chlorinated solvents, and many acids. FKM also operates across an extended temperature range of -10°C to +200°C, making it suitable for handling parts in chemical processing, pharmaceutical manufacturing, fuel system assembly, and any environment where aggressive chemical exposure is routine.

The bellows pad shape ("B" prefix) provides angular compensation for reliable vacuum sealing on tilted or slightly curved workpieces, while the 10mm buffer stroke ("K10") adds shock absorption for delicate part protection. This dual-compliance design — bellows for angular variation plus buffer for height variation — maximizes first-pass pick reliability in challenging automation environments where both surface geometry and chemical exposure demand premium pad materials.

Connected via a ø4mm one-touch fitting ("04") with the "A10" buffer body sized for 13mm class pads. This pad is RoHS compliant and part of SMC's ZPT series spanning 2 to 125mm diameters across six material options for complete application coverage.
