FDA approved food grade round silicone washer

A round silicone washer provides a shaped contact layer around a matching opening or fixing. In equipment used with food, its dimensions and material should be developed for the particular location where the washer will sit, including whether food or cleaning fluid can reach its edges.

Choose the silicone formulation for the intended substances, contact duration and cleaning conditions. A general approval reference does not establish suitability for every finished assembly. The washer geometry should allow the joint to close as designed without leaving an unintended pocket where residue can collect.

Match the bore and outer area to the mating faces and check the installed compression. During routine maintenance, follow the equipment's cleaning and replacement procedure, inspecting the washer and the adjacent surfaces together. Remove damaged material rather than turning a worn face inward. If deposits repeatedly accumulate at one edge, review the joint geometry and fit instead of treating the washer as a separate component with no connection to the surrounding design.
