Special-shape rubber silicone washer/thin gasket with high quality

A thin silicone washer with a custom gasket outline can close a shaped interface while occupying limited space between mating parts. This custom rubber or silicone component can follow a nonstandard outline, including the openings and edge features required by the assembly. Its thickness should be established alongside the available closing gap.

Thin sections need support from the mating surfaces. A narrow bridge between openings can move during installation, while an unsupported edge may become trapped as the parts close. Include the complete perimeter and hole positions when defining the gasket, rather than reducing it to an overall width and length.

Select the compound for the substances, temperature, and contact requirements of the joint. Fit the gasket on clean surfaces and verify its orientation before bringing the parts together. Where the outline is asymmetric, use its distinguishing features to confirm alignment. Close the assembly in its intended sequence so that the gasket remains flat. When replacing it, match the specified section instead of adding extra thickness to compensate for damage elsewhere in the joint.

Material options

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

Hardness selection

Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Its thickness should be established alongside the available closing gap.

Custom dimensions

Include the complete perimeter and hole positions when defining the gasket, rather than reducing it to an overall width and length.

Fit & assembly

A narrow bridge between openings can move during installation, while an unsupported edge may become trapped as the parts close.

Use & inspection

When replacing it, match the specified section instead of adding extra thickness to compensate for damage elsewhere in the joint.
