  • The Invisible Seal

    Gaskets and seals are important to a number of industries where round objects need to be sealed by an o-ring. If the objects being sealed are in a spot where they are visible to traffic it is important to have everything color coded. So what if the object is clear? Fortunately, there is such a thing as a clear o-ring. O-rings are made in all colors. However, clear is the most tedious to produce. Silicone is the preferred material to make clear o-rings, but silicone tends to have a semi-clear...

  • Silicone and Silicon

    The word silicon can be heard often, not incredibly often, but often enough that most of us are aware of it. But, it may surprise you to know that it is in fact the second most common element on Earth. The only element ahead of it is oxygen. Knowing this, I feel like I should know a little more about it. Jons Jacob Berzelius is given credit for the isolation of the element, having done so back in 1824. It has a chemical symbol of Si, a periodic number of...

  • Kits and Replacements

    O-rings are found in many settings from automobiles to industry. However, in these intense industries the products can begin to wear down over time and need replacements. For this reason many suppliers provide o-ring kits. These small to large kits contain various sizes of o-rings for when current used o-rings begin to get faulty and must be replaced. Typically they are available in standard measurement and metric measurement sizes for easy transfer. While many sizes are available in the kits, typically they are only made of one material such as...

  • Silicone Vs. Polyurethane

    The basic characteristics of silicone and polyurethane make them ideal for the production of O-rings, but each have high performance in some areas and low performance in others. This is why it is extremely important to be knowledgeable about the product you are using and the conditions that it will need to withstand. So, let's discuss the major points of these two products. The silicone O-ring is the general standard when it comes to sealing products because they are simple to use, inexpensive to produce, and quite versatile. The qualities...

Industry Information

Silicone O-Rings

Silicone O-rings are round, highly temperature resistant devices that seal connecting pieces in machinery where flexibility and longevity are important. These O-rings are resistant to UV damage, corrosion, oils, chemicals and solvents. They are used for electrical insulation and are dielectrically stable. Silicone O-rings aren’t toxic, and therefore are FDA approved to be used in food handling equipment and appliances.

Silicone is an inert material, meaning it doesn’t react with most chemicals. The medical industry therefore uses it for applications like complex medical implant systems that have moving parts requiring a sealant such as an o-ring. The aerospace, automotive, food processing and jewelry industries use silicone O-rings in their machinery and tubing or piping systems as well. Silicone o-rings sometimes require the use of a lubricant, if the two pieces it is wedged between are moving pieces. The lubricant protects the silicone from quick deterioration. This is a common thing among all o-rings, whether they are metal or rubber, flat or round. Silicone o-rings are naturally an opaque and partially transparent color, which is why they are sometimes called clear o-rings. However, clear o-rings are also produced from other materials such as Teflon, and silicone o-rings can be altered to match any color available.

Silicone is an element derived from quartz. For use as an o-ring, three other chemicals are added; methyl, phenyl and vinyl. The combination of these four elements make the silicone used for silicone o-rings a synthetic material. Its temperature resistance ranges from -60°C to 225°C, and some special varieties are able to range from -100° to 300°C. They come in many different sizes, and are formed by joining a piece of silicone cord at its ends. Silicone itself is developed in two major fashions. Liquid silicone rubber, also known as LSR, must be heated and cured to reach its moldable state, while high consistency rubber (HCR) must be melted and then cooled before it can be set in a solid state. LSR is the silicone best suited to o-ring designs. Silicone O-rings are odorless, non-toxic and will never grow mold. Although they are flexible in low temperatures, they have low tensile strength, poor tear strength and low wear resistance. A Teflon sleeve is one possibility for additional protection from erosion since Teflon is stronger it works well as a cover for less durable o-ring materials. O-rings made of silicone are therefore better suited to perform in higher temperature applications.
