Custom made NBR/silicone/Rubber Motorcycle Oil Seal Washer

A motorcycle oil seal washer must match the connection in which it is used. This custom NBR or silicone offering should be selected by the required material formulation, opening size, outside boundary, and section. Different oil-contact positions on a motorcycle may use different sealing arrangements.

Identify the exact seat and fastening method before choosing a replacement. A washer fitting around the same nominal feature may still have an unsuitable thickness or contact width. The compound needs to suit the actual oil, temperature, and conditions at that location.

Service the connection through the motorcycle's intended procedure. Clean the mating faces and inspect for damage before positioning the washer. Use the specified fastening method rather than tightening harder to compensate for an unsuitable seal. During inspection, compare recurring damage with the corresponding seat. Replace with the correct compatible profile and material, preserving the original joint geometry instead of substituting an approximately sized rubber ring from another application.

Material options

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

Hardness selection

Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Compare the proposed compound firmness using the actual washer thickness and contact width, rather than matching only the feature through its center.

Custom dimensions

Different oil-contact positions on a motorcycle may use different sealing arrangements.

Fit & assembly

Use the specified fastening method rather than tightening harder to compensate for an unsuitable seal.
