Capacitive rubber tips/ Custom rubber crutch tips

These custom rubber tips are developed around a mating end and an intended contact surface. The socket shape, engagement depth and outer profile determine how the tip is retained and where the force reaches the rubber. Those details should be established before color or other visible features are selected.

ETOL offers dimensional customization and options for rubber material, hardness and branding. Identify the actual role of the component when defining its construction. A tip used to cover a shaft end has different functional requirements from one intended for an electrical contact interface, even if the outside shapes are similar.

Check the fit on the complete mating part, including any corner, taper or shoulder that controls insertion. The rubber should settle into its intended position without a thin section being stretched over an obstruction. Inspect the contact face after assembly and ensure that the component remains retained during the intended handling motion. Keep the inside clean during fitting, and replace a damaged or permanently distorted tip rather than relying on extra force to restore its original shape.

For a tip shared across several designs, compare the mating ends directly. An identical outer appearance does not establish the same socket engagement, and a subtle shoulder change can leave one version incompletely seated.

Material options

Custom rubber compound and color, selected for the contact conditions and required geometry.

Hardness range

30–90 Shore A for rubber. Assess the grade against this fit requirement: The rubber should settle into its intended position without a thin section being stretched over an obstruction.

Custom profile & fit

Check the fit on the complete mating part, including any corner, taper or shoulder that controls insertion.

Assembly considerations

An identical outer appearance does not establish the same socket engagement, and a subtle shoulder change can leave one version incompletely seated.

Design check

Inspect the contact face after assembly and ensure that the component remains retained during the intended handling motion.
