Custom molded silicone rubber gasket/EPDM rubber seal

An EPDM rubber seal should be selected for the actual medium and temperature at its joint, while a silicone gasket configuration requires its own material assessment. The two can share a custom outline without sharing the same service suitability. Keep the selected compound identified alongside the geometry so replacement preserves the intended configuration.

Check the mating faces, local sealing width, and available compression. The gasket should follow locating features naturally and remain supported around openings. Include cleaning substances and any movement that changes the contact in the material and joint assessment.

Install flat on clean surfaces without stretching the perimeter. Inspect for folds or an edge displaced as the faces close. During service, compare changes in rubber condition with the actual exposure and inspect local cuts against the hardware. A compound substitution should not be used as a general response to damage caused by a sharp seat or an unsupported gap that needs correction in the assembly.

Material options

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

Hardness selection

Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. A compound substitution should not be used as a general response to damage caused by a sharp seat or an unsupported gap that needs correction in the assembly.

Custom dimensions

The gasket should follow locating features naturally and remain supported around openings.

Fit & assembly

Inspect for folds or an edge displaced as the faces close.

Use & inspection

During service, compare changes in rubber condition with the actual exposure and inspect local cuts against the hardware.
