Heat resistant industrial silicone rubber suction cup with screw

An industrial silicone rubber suction cup used near heat should be selected for the temperature at the cup and its contact surface. The screw attachment, flexible body, and rim need to maintain their intended geometry under the relevant operating cycle. A general silicone description does not establish holding behavior at every temperature or surface condition.

Check the thread interface and mounting clearance, then assess the load direction and any offset from the contact surface. The cup profile should suit the actual texture and curvature beneath the rim. Include the real vacuum operating and release arrangement where one is used.

Fit the hardware without twisting the rubber body and keep the contact region clean. Evaluate the complete assembly under its actual conditions, including movement and temperature changes. During maintenance, inspect both the screw region and rim for damage or persistent distortion. If contact changes as the equipment warms, review the surface, mounting geometry, and compound before assuming a tighter screw connection will restore the intended seat.

Material options

Custom silicone compound; formulation and geometry developed together.

Hardness selection

Silicone options: 20–80 Shore A. Check the thread interface and mounting clearance, then assess the load direction and any offset from the contact surface.

Custom geometry

The cup profile should suit the actual texture and curvature beneath the rim.

Fit evaluation

Evaluate the complete assembly under its actual conditions, including movement and temperature changes.

Color & OEM

Custom colors; OEM markings outside the suction contact face.
