Product Overview

Rubber chair foot tips provide fitted contacts beneath chair legs. Custom molding allows the receiving profile to follow the end shape, including a taper or corner detail. The base should remain under the leg while the rim holds the tip in its intended position.

Inspect the bare end before fitting. Rough tube edges, seams or damage can cut into a new tip from inside. Measure the finished leg rather than copying a worn rubber cavity that may have stretched through use.

Seat each tip fully and compare the chair's contact on its intended floor. The foot should not curl to one side when the chair is moved normally. Choose the rubber formulation for the actual floor finish and cleaning conditions, and keep the bases free of grit. During maintenance, inspect the inner bearing area as well as the outside wall. A tip can wear thin beneath the leg while still looking intact around its perimeter. Replace it with the matching profile so the chair retains its original seated height and support relationship.

Material options: Rubber compound options, customized alongside the profile and contact conditions.
Hardness selection: Solid rubber options: 30–90 Shore A. Seat each tip fully and compare the chair's contact on its intended floor.
Custom geometry: Custom molding allows the receiving profile to follow the end shape, including a taper or corner detail.
Fit evaluation: Rough tube edges, seams or damage can cut into a new tip from inside.
Color & OEM: Custom colors; OEM markings clear of the working interface.

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.
