High Temperature Resistance

The ability to withstand extreme temperatures is essential in many industries that utilize O-rings. This is because heat can be one of the most destructive forces when it comes to compound deterioration, so finding an o-ring that can withstand fluctuations in temperature is important.

Silicone o rings can hold their shape, flexibility and seal at very high temperatures, making them a good choice for industries that require resistance to high levels of heat. This includes the electronics industry, where silicone o-rings can provide thermal stability and efficient insulation. They can also withstand the rigours of the automotive industry, where they can be used to provide tight connections between moving parts.

Additionally, silicone o-rings are non-reactive with chemicals and therefore, they do not release toxic fumes or leach into products. This makes them suitable for use in the medical and food industries, where they are used in equipment like life-support machines.

There are several different types of silicone o-rings, depending on your requirements and the conditions in which they will be used. The most popular is silicone rubber, which can be used in a range of environments and has excellent heat and ozone resistance. Other options include PTFE, FEP, and EFLAS which all have a similar level of performance to silicone. However, the chemical composition of each material varies slightly, so you should carefully consider the specifics of your application before choosing a particular type of O-ring.

Low Compression Set

The ability of Silicone o rings to withstand high and low temperatures is a major benefit. The wide temperature range allows these seals to remain functional in a Silicone o rings variety of environments and is especially helpful for the food and beverage industry, where equipment may frequently change between hot and cold applications.

Additionally, Silicone’s ozone, weathering and UV resistance is very beneficial for industries in harsh outdoor environments. These characteristics make Silicone o rings a great choice for the medical, aerospace, semiconductor and automotive industries.

A common failure mode for o-rings is the compression set, which occurs when the elastomer fails to return to its original size after being compressed to a constant force. This can occur due to the o-ring’s material not being compatible with system chemicals or it may result from exposure to high temperature or dynamic environments.

To avoid compression set, be sure that the o-ring fits its gland correctly. It is also important to check that the o-ring is not being subjected to excessive mechanical stress, such as twisting or pinching. Xometry’s engineering and manufacturing capabilities allow us to provide a high-quality o-ring that will perform in even the most demanding situations. Contact a representative today to see how our customization and rapid prototyping services can improve your process. In addition, we can also help you select the right materials for your specific needs.

Good Resistance to Chemicals

Silicone o rings are an ideal silicone face mask brush wholesale choice for sealing in a variety of environments and applications. They are extremely durable and long-lasting, providing a high level of performance in static applications with a wide temperature range.

They have an exceptional resistance to ozone, UV radiation, and many different types of oils. In addition, they are physiologically neutral and non-reactive to most materials, making them an excellent choice for use in medical applications.

These qualities make silicone o rings a great choice for a wide range of industries and applications, from electronics to automotive. They are commonly used in electronic devices to provide thermal stability and protect delicate components from electrical damage. They are also found in the automotive industry for the same reasons, as well as in food and beverage and medical applications due to their bio-inert nature.

Injection molded silicone o-rings are available with a number of additives, including reinforcing fillers for improved tensile strength, flame retardants, and conductive compounds to meet specific application requirements. Stockwell Elastomerics also custom molds fluorosilicone rubber to create o-rings with greater chemical resistance for specialized aerospace applications. We can even injection mold o-rings in custom geometries to improve installation and fit in non-standard gland configurations. Choosing an o-ring material can be difficult because of the vast number of available options, but understanding the advantages and disadvantages of each type of o-ring material can help you make the right decision for your needs.


A silicone ring may not be traditional for a wedding band, but these rings are available in a wide array of styles to suit any style. They also have more durability than traditional ring materials, so they can be worn for years without worrying about the ring breaking down or becoming brittle.

Silicone is a popular material for o-rings and seals because it offers an excellent combination of properties. The material is very flexible and can resist a wide range of temperatures and chemicals. It also has low compression set, meaning it will retain its shape and sealing capabilities even after prolonged periods of compression. Additionally, it is a good electrical insulator and can withstand high voltages.

Rubber silicone O-rings are ideal for use in a variety of industries, including automotive, aerospace, and medical. They are able to withstand extreme temperatures and pressures, making them perfect for aircraft engines and hydraulic systems. They are also biocompatible and resistant to high temperatures and sterilization processes, which makes them a great choice for medical devices.

For food processing equipment, it is important to have a strong and reliable seal that will prevent leaks. Silicone FDA metal detectable O-rings are a great option for these applications because they can be detected easily by inspectors and are safe to come into contact with food. They are also durable, easy to clean, and affordable.
