Custom made molded FDA silicone rubber gasket good sealing

A silicone rubber gasket used in a regulated contact application needs a defined material formulation and a suitable mechanical design. Material suitability must be evaluated for the finished component and the conditions encountered throughout its intended use. The actual contact medium, temperature, cleaning conditions, and applicable requirements determine suitability.

Choose the molded profile around the mating faces and intended compression. The gasket should remain located without unsupported edges or inaccessible areas that complicate the required cleaning routine. Its seating condition needs to be considered separately from material compliance.

Evaluate the complete joint for the specified function and exposure. Before assembly or reuse, inspect the gasket and mating surfaces for residue, cuts, and lasting distortion. A broad material description cannot establish a pressure rating, service interval, or suitability for a different contact application. If the joint is changed, revisit both the mechanical fit and the material requirements rather than assuming that the same silicone part remains appropriate because its nominal dimensions still match.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Choose the molded profile around the mating faces and intended compression.

Custom dimensions

If the joint is changed, revisit both the mechanical fit and the material requirements rather than assuming that the same silicone part remains appropriate because its nominal dimensions still match.

Fit & assembly

Before assembly or reuse, inspect the gasket and mating surfaces for residue, cuts, and lasting distortion.

Use & inspection

The gasket should remain located without unsupported edges or inaccessible areas that complicate the required cleaning routine.
