We provide high quality Industrial Rubber Radius Rings that are solid-rubber, doughnut shaped seals. When pressed between two mating surfaces, O-rings block the passage of liquids or gases. These rings can form a static or dynamic seals. A static seal is where the O-ring does not move and is used simply for containing pressure or maintaining a vacuum. Dynamic seals can be reciprocating (like a piston and cylinder), or rotating (shaft rotating in a housing). We can provide these Industrial Rubber Radius Rings in different specifications.
