Custom made silicone sealing O-ring/EPDM rubber gaskets

EPDM rubber gaskets should be specified for the actual mating faces and service exposure of their joints. A silicone O-ring option needs a different section and material assessment, even where both appear in the same equipment. Keep the intended format and compound tied to each location rather than choosing by a similar outline.

Define thickness, contact width, openings, and locating features for the gasket. Check the available compression and support around narrow regions. Select the formulation for the medium, temperature, and cleaning process that reach the installed part.

Fit the gasket flat without pulling it to align distant holes. Bring the faces together evenly and inspect for a displaced edge. During maintenance, examine local damage beside the corresponding hardware feature. Correct uneven support or a sharp seat before replacement instead of choosing a thicker gasket to conceal the mismatch, which can alter the closing condition across other sections that were already correctly supported.

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. Check the available compression and support around narrow regions.

Custom dimensions

Define thickness, contact width, openings, and locating features for the gasket.

Fit & assembly

Fit the gasket flat without pulling it to align distant holes.

Use & inspection

During maintenance, examine local damage beside the corresponding hardware feature.

Photos illustrate structure or material only. The EPDM gasket contact width and locating openings differ from the groove section needed by the silicone O-ring option. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.
