Small round silicone protecting rubber seal bushing

A small round rubber seal bushing needs clean, compatible mating surfaces around its outside and center passage. The custom silicone geometry can follow the assembly, with the section selected for its intended support and contact. Protecting the molded edges during installation helps preserve that fit.

Check the entrance of the outer seat and the end of the component passing through the center. Burrs or sharp projections can cut the rubber before it reaches its final position. The available depth should let the bushing seat naturally without an unexpected shoulder loading one end.

Choose the compound for the substances and temperature at the interface. Guide the part into place without dragging it sideways, then inspect the exposed ends for folding. Secure the assembly using its designed arrangement rather than arbitrarily squeezing the rubber. During care, examine the center opening and the retained edge for damage. Match the original profile and material when replacing the component so that the intended contact remains continuous around the small round seat.
