Custom made compression molded soft rubber gasket ring

A compression molded soft rubber gasket ring can follow the circular contact path of a custom joint. Material, size, and color can be adapted to the assembly. The soft section needs appropriate support from the mating parts so that its deformation occurs where the design intends.

Define the ring's inside diameter, outside diameter, and thickness alongside the seat. A wide unsupported edge can be displaced as the joint closes, while an unsuitable inner opening can catch against a locating feature. The available compression should be controlled by the assembly rather than judged only by how soft the loose ring feels.

Choose the compound for the medium and temperature at the interface. Install the ring flat on clean surfaces and check that it remains centered before closure. If fasteners establish the joint position, use their intended sequence and settings. During servicing, inspect the ring for extrusion or a lasting change in section. A replacement should reproduce the required geometry and material rather than simply being softer or thicker than the removed component.

Material options

Hardness selection

Rubber: 30–90 Shore A. The available compression should be controlled by the assembly rather than judged only by how soft the loose ring feels.

Custom dimensions

Define the ring's inside diameter, outside diameter, and thickness alongside the seat.

Fit & assembly

Install the ring flat on clean surfaces and check that it remains centered before closure.

Use & inspection

A replacement should reproduce the required geometry and material rather than simply being softer or thicker than the removed component.
