Depending on the material they are made of, O-rings can come in many different colors like black, brown, green, red and blue. Only a few, however, offer a transparent color. Silicone, polyurethane and Teflon are able to produce a clear o-ring product. Without any color additives, these materials are semi-clear, not totally transparent in natural form. However, certain additives are able to produce ultra-clear silicone.
Clear O-rings are doughnut shaped, flat and thin. The positive characteristics of this mechanism, considered a seal or gasket, include flexibility, chemical inertness and odorless ness when in a solid state. As just one branch of the o-ring family, clear o-rings stand out because of their transparency. They are generally transparent in both UV light and visible light. Clear o-rings are used in the medical, pharmaceutical, food processing, dairy and biotech industries, to name just a few. Like all o-rings, they are used for sealing and gasketing applications. O-rings create a seal when they are pressed between two or more parts of a product or system while it is being assembled. The product or system that needs sealing usually involves vacuums or piping. O-rings are set up as a static seal or with dynamic joints. As a static seal, clear o-rings are permanently sealed in one spot, assuring that whatever substance within the system will not leak out. Dynamic joints refer to the part of o-rings in a fluid system like a hydraulic cylinder. In such a situation, an o-ring would need to be well- lubricated to protect is from the fast deterioration that comes from being in between moving parts.
