Sealed soft food grade silicone o ring rubber o rings

A soft food grade silicone o ring should be developed for the actual food-contact joint and its cleaning cycle. The chosen silicone formulation, section and groove must work together so the ring remains seated as required during operation and after the equipment is cleaned or reassembled.

Select the material for the relevant contents, contact duration and temperatures. Softness is one design variable rather than a general guarantee of sealing. The joint needs enough support for the selected ring without forcing the rubber into an unintended gap.

Fit the ring using the equipment's designated method and inspect the full circumference before closing the joint. Where maintenance removes the ring, handle it without stretching the section and clear residue from its seat before replacement. Check for cuts or a lasting change in shape. Do not use a similarly soft spare without matching its compound and dimensions, since a different formulation or section can behave differently in the same food-equipment assembly.

Material options

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

Hardness selection

Silicone: 20–80 Shore A. Do not use a similarly soft spare without matching its compound and dimensions, since a different formulation or section can behave differently in the same food-equipment assembly.

Custom dimensions

The joint needs enough support for the selected ring without forcing the rubber into an unintended gap.

Fit & assembly

The chosen silicone formulation, section and groove must work together so the ring remains seated as required during operation and after the equipment is cleaned or reassembled.

Use & inspection

Where maintenance removes the ring, handle it without stretching the section and clear residue from its seat before replacement.
