Custom made rubber bushing silicone rubber wire sleeve

Rubber wire bushings molded in silicone form custom passages around wiring. Each bushing can be adapted to a receiving feature, with a sleeve portion that follows the wire beyond that location. The design should keep the passage aligned with the intended route rather than forcing the wire around an abrupt edge.

Use the actual wire or bundle dimensions when defining the inside profile. A group of loose wires may need a different passage from a single jacketed cable. The outer seating area also needs to match the component that holds the sleeve, including available depth and surrounding clearance.

Fit the part without rolling the sleeve or pinching a wire between the rubber and its seat. After routing, check that the wire does not pull the bushing to one side. Provide the support needed by the complete assembly instead of relying on sleeve contact alone to carry a hanging cable. During maintenance, inspect the concealed entry area when access is available and replace a sleeve whose wall has been cut or worn through.

Material options

Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Silicone: 20–80 Shore A. Coordinate flexibility with the sleeve wall and wire route so the bushing maintains a supported passage without creating an abrupt bend.

Custom dimensions

Use the actual wire or bundle dimensions when defining the inside profile.

Fit & assembly

Provide the support needed by the complete assembly instead of relying on sleeve contact alone to carry a hanging cable.

Use & inspection

During maintenance, inspect the concealed entry area when access is available and replace a sleeve whose wall has been cut or worn through.
