One of the most cost-effective and most popular o rings offering a whole host of benefits is that of silicone rubber o rings.
Known for their flexibility and low compression characteristics, silicone o rings are often the seal of choice for applications within the medical, aerospace, automotive, and electronics industries.
In this post, we take a look at some of the main benefits and what this particular type of o-ring can bring to your application.
Silicone o rings UK
Silicone o rings are one of the most widely used types of sealing element due to their effective sealing capabilities and suitability to numerous industries; they’re also simple to use and offer good value for money.
Due to its flexible nature, silicone sealing is also considered the industry standard and the `go-to` o ring choice for many manufacturers.
Silicone compound materials, such as carbon, hydrogen, and oxygen, along with a silicone base polymer, are used to produce a range of general-purpose o rings, all providing good to average levels of strength (you will find various grades of o rings available; the grade you choose will be dependant on your exact requirements). Depending on requirements and specifications, these types of o-rings can also be formulated to include inert fillers.
With excellent weathering capabilities, resistance to ozone, acid, and heat, as well as being non-reactive, stable, and cost-effective to manufacture, silicone is a durable choice.
Benefits of silicone o rings
Wide temperature range
Silicone rubber o rings are an incredibly practical solution when applications are operating with various low and high-temperature ranges. Able to withstand and maintain their shape and performance, silicone o rings are an excellent choice for 99.9% of environments in which they are placed.
They can maintain their high performance in temperatures ranging from -75 degrees Celsius up to 230 degrees Celsius, with some newer polymers able to still operate in temperatures up to 315 degrees Celsius.
Due to the elasticity of this type of o ring, even in the lowest of temperature ranges, silicone o rings keep their flexibility, providing you with peace of mind that they will always perform at their best.
Silicone o rings also maintain their flexibility and composure when exposed to certain chemicals, i.e., alkali and acid elements.
When silicone o rings are stored correctly (in clean and dry spaces away from direct sunlight and UV rays), they can last boundless years. This is important to bear in mind as the silicone counterpart Nitrile o rings may only have a lifespan of 15 years.
Reducing ongoing maintenance requirements and the need for replacement.
Low compression set
Silicone o rings can still perform at high pressures and temperatures due to the makeup of their material.
Available in a choice of colour
This may not be a big selling point; however, for some applications, having this choice is required, especially for consumer-facing applications.
Available from o ring suppliers in red, green, blue, and clear, no matter the colour you choose, the strength of the material is not compromised; you can simply choose the one that is best suited to your application.
For all we have mentioned, the advantages of using silicone o rings, this material choice does come with some weaknesses, which you should be aware of.
For example, this type of o ring has poor tensile strength and low shear strength. It isn’t resistant to abrasion, and also has low impermeability.
This makes silicone o rings unsuitable for applications that involve steam or oil.
