Food grade silicone rings custom made rubber gasket washer

Custom silicone rings can form a gasket or washer interface in food contact equipment. The ring's bore, outer dimensions, and section need to match the supporting joint. A flat washer profile and an O ring section have different seating requirements, so the intended configuration should be established first.

Choose the silicone formulation for the actual food, temperature, and cleaning process. The joint should locate the ring without requiring it to be twisted or stretched into a mismatched shape. Clean the mating surfaces before assembly and check that the rubber remains in its intended seat as the parts close. Consider access for cleaning after use, especially where residue can remain beneath an edge or inside a groove. Inspect the ring during disassembly and preserve the correct material and section when replacing it. A similar outside diameter does not show whether another ring will receive the same support or compression within the food contact assembly.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. A similar outside diameter does not show whether another ring will receive the same support or compression within the food contact assembly.

Custom dimensions

The ring's bore, outer dimensions, and section need to match the supporting joint.

Fit & assembly

Clean the mating surfaces before assembly and check that the rubber remains in its intended seat as the parts close.

Use & inspection

Consider access for cleaning after use, especially where residue can remain beneath an edge or inside a groove.
