Factory supply OEM waterproof dustproof rubber flange bushing

A rubber flange bushing uses its projecting flange to define a seated edge against the receiving surface. That feature can cover the perimeter of an opening, but waterproof or dustproof performance depends on the complete fit, including the central passage and adjoining parts. A wide flange alone does not establish a sealed assembly.

Match the body to the receiving bore and the flange to the available supporting face. If the surrounding surface is stepped or uneven, part of the flange may remain lifted. The installed compression should allow the intended contact without folding the rubber under the mounting edge.

Check seating around the full circumference and inspect the inside passage after the mating component is fitted. Evaluate any ingress requirement under the intended conditions of use. During servicing, look beneath accessible flange edges for trapped debris and check whether movement has pulled the bushing from its seat. Refitting should restore the original geometry rather than rely on extra pressure against an incorrectly matched opening.

Material options

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

Hardness selection

Rubber: 30–90 Shore A. Refitting should restore the original geometry rather than rely on extra pressure against an incorrectly matched opening.

Custom dimensions

Match the body to the receiving bore and the flange to the available supporting face.

Fit & assembly

Check seating around the full circumference and inspect the inside passage after the mating component is fitted.

Use & inspection

During servicing, look beneath accessible flange edges for trapped debris and check whether movement has pulled the bushing from its seat.
