Silicone rubber gaskets are vital of modern society

Silicone rubber gaskets are available in a variety of shapes and sizes and are used in many different applications.

A silicone rubber gasket's main function is to create a tight seal.

Surfaces and the silicone rubber gaskets are compressed together to create a good seal.In the case of silicone O-rings may need to be some movement, is often sealed by a lubrication fluid to be done.  A few gaskets require the application of sealants directly to the gasket surface in order for it to function properly.

Silicone gaskets are widely used in all areas, and these car engineering, aerospace, construction and catering count, just to name a few. They are very common between two or more surfaces, on which a fluid leak or air must be included.

They are rings of silicone, commonly used for all types of plumbing and hydraulic applications, enabling even a small amount of motion between two surfaces, while maintaining efficiency. 

Over time a silicone gasket dries out and loses its elasticity.When this is noticed, the silicone gasket must be immediately replaced to prevent dangerous situations.

Properties and uses silicone rubber gaskets

Silicon is extremely versatile and has the ability to withstand extreme temperatures, humidity and has repelling properties.

For this reason, it is often used in sealants, adhesives, cooking utensils. medical equipment and for isolating lubricants.

Silicones are polymers composed of chemical elements, including oxygen, hydrogen and silicon.

This combinaton resists cracking, shrinking and migration caused by thermal cycling. The silicone seals are also Resistant to oil, water, anti-freeze, and transmission fluid as well as dries tough, yet flexible, withstanding a huge temperature range of between -50°C to +300°C.

Application examples of silicone rubber gaskets

Silicone rubber gaskets for plumbing

A major requirement of today’s plumbing, such heavily used faucets, water softeners and toilets, is a long-term seal. Silicone gaskets, or seals can be custom moulded to fit any application, providing superior strength, more aesthetic design, and improved functionality compared to other plumbing materials.

Silicone rubber gaskets for car engines

Car engines need gaskets – and silicone is a good material to use.

Specifically, they are used as valve covers – to form a protective shield over an engine’s valves. The valve cover gasket is a piece of rubber or cork, which is used to keep a tight seal.

This, however, is a common place to see oil leaks in car engines, since silicone gaskets can deteriorate over a long period of time.

Because the silicone gaskets that seals the valve cover to the head, eventually wears out and fails you may see leaking oil – although sometimes this may be caused by something else. It is therefore important to change them every so often to prevent this mishap.

Silicone rubber is a newer material, since cork rubber used to be the material of choice in car engines. There are other types of rubber available , but none that can mould to the shape of the engine quiet as well as silicone. The very latest cover gaskets are a rigid carrier with a moulded-silicone sealing bead.
