Product Overview

M8 thread glass suction cups combine a suction contact with a threaded mounting interface. The M8 designation identifies a nominal thread size, while the cup's dimensions and compound remain separate choices. ETOL offers custom size, color and rubber material options for this range.

The suction face needs a smooth, clean surface to establish its contact. When attaching hardware, keep the load path aligned with the cup rather than applying an unintended twisting or peeling force at the edge. A secure thread connection cannot compensate for a cup that is sitting partly over a surface defect.

Check the mating thread and required engagement before assembly. Match the pitch, usable thread length and suction arrangement to the attached hardware, then evaluate holding performance with the selected cup on its intended surface. Avoid rotating the cup body against the glass as a way to tighten the attached hardware.

Evaluate the complete attachment on the intended glass surface and in its working orientation. Inspect the contact lip for damage and keep residue away from it during handling. Release suction by the method appropriate to the chosen design before moving the assembly; pulling the mounted item sideways can load the cup edge in a way that differs from its intended service.

Material options: Rubber compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. When attaching hardware, keep the load path aligned with the cup rather than applying an unintended twisting or peeling force at the edge.
Custom geometry: Match the pitch, usable thread length and suction arrangement to the attached hardware, then evaluate holding performance with the selected cup on its intended surface.
Fit evaluation: Check the mating thread and required engagement before assembly.
Color & OEM: Custom colors; OEM markings outside the suction contact face.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
