Custom molded silicone pipe tube rubber sleeves bushing

Custom silicone rubber sleeves bushing components need a wall thickness that suits both the inside part and the surrounding seat. The available radial space determines how much rubber can be installed without excessive squeezing. A thicker wall may reduce clearance or alter the position of the covered pipe or tube.

Define the bore, outside dimensions and engagement length using the completed assembly. Consider any clamps or housings that compress the rubber after insertion. The selected silicone formulation should suit the actual medium, temperature and contact conditions.

Evaluate the fitted shape once all surrounding hardware is in place. Check for extrusion at the ends, a distorted internal passage or contact concentrated at one side. If the component is intended to carry fluid or pressure, assess that duty within the complete system rather than inferring it from the tubular shape. During inspection, compare the rubber's contact marks with the receiving surfaces. Repeated uneven compression can indicate misalignment or an unsuitable seat that should be corrected before changing only the sleeve thickness.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Repeated uneven compression can indicate misalignment or an unsuitable seat that should be corrected before changing only the sleeve thickness.

Custom dimensions

Define the bore, outside dimensions and engagement length using the completed assembly.
