Silicone products silicone cap silicone rubber feet for chair

Silicone rubber feet for chair use can be custom molded as caps around compatible leg ends. The material and wall geometry work together to establish the fit, while the base controls the contact beneath the chair. Flexibility should support the intended installation rather than compensate for an incorrect internal size.

Measure the leg at the engagement region and check its usable depth. The cap should seat without bunching around a taper or stopping early on a projection. Its floor-facing section needs to remain compatible in height with the chair's other supports.

Fit the feet through the intended arrangement and assess the chair on its normal surface. Keep the contact faces clean and check for a cap that lifts or twists when the chair is moved. During maintenance, inspect the mouth and internal contact region for tears or permanent stretching. A replacement should match the complete cap profile and selected material so that the original seated position and support height are preserved.

Material options

Custom silicone or rubber formulation, with dimensions and color adapted to the mating component.

Hardness range

Silicone: 20–80 Shore A; rubber: 30–90 Shore A. Assess the grade against this fit requirement: Flexibility should support the intended installation rather than compensate for an incorrect internal size.
