Custom made NBR suction cup two-double suckers

An NBR suction cup in a double-sucker arrangement needs each intended contact area to meet its surface properly. The presence of two suction features does not guarantee equal loading, particularly if the surfaces are misaligned or one cup encounters a seam. The surrounding assembly should allow the contact geometry to work as designed.

Check the spacing, connection and available movement before selecting the part. A rigid arrangement can leave one contact partly lifted if the receiving surface is uneven. NBR compound selection must also reflect the substances and conditions around the cup; it should not be treated as universally compatible with any oily or outdoor setting.

Clean the contact areas and inspect the rims for cuts before attachment. Evaluate retention under the actual direction of force and intended movement without inferring a load rating from the number of cups. Release each contact through its intended edge or mechanism rather than pulling the assembly away by force. Replace damaged rubber when either contact can no longer form its intended seal.

Material options

NBR compound options, customized alongside the profile and contact conditions.

Hardness selection

Solid rubber options: 30–90 Shore A. Release each contact through its intended edge or mechanism rather than pulling the assembly away by force.

Custom geometry

A rigid arrangement can leave one contact partly lifted if the receiving surface is uneven.

Fit evaluation

Check the spacing, connection and available movement before selecting the part.

Color & OEM

Custom colors; OEM markings outside the suction contact face.
