PFYN Flat Vacuum Suction Cups with G1/4 Female Thread

PFYN size and connection reference

PFYN-60, PFYN-80 and PFYN-95 are single-layer flat cup options with a listed G1/4 female connection. Choose the diameter that fits the available sealing surface, then select the material for the actual workpiece and operating conditions.

Nominal diameter is not a verified effective sealing diameter or a payload rating. Check the selected drawing and validate holding performance on the actual part.

Applications and Suitable Workpieces

PFYN Flat Vacuum Suction Cups with G1/4 Female Thread: Flat suction cups provide stable positioning on smooth, flat or only slightly curved non-porous workpieces.

Recommended applications

• Sheet metal, glass, smooth plastic parts, coated panels, electronics panels and other flat industrial components.
• Machine loading and unloading, sorting, assembly, transfer and general automated pick-and-place.
• Thin sheets where a low internal volume and controlled vacuum can help reduce movement during pickup.

Model and selection notes

• PFYN60, PFYN80 and PFYN95 identify diameter; white silicone and black NBR versions use the same listed G1/4 female connection.
• Select diameter according to the available sealing area, workpiece mass, acceleration and mounting direction.
• Silicone suits clean parts and wider temperature conditions; NBR suits general industrial use, abrasion and lightly oily surfaces; conductive grades are only for static-sensitive handling where identified.
• Rough, porous, deeply curved or perforated surfaces may not seal. Confirm holding force on the actual part with an appropriate safety factor.
