There are different kinds of mechanical seals available in the market depending on the applications they are required for and are involved in.
The Teflon Seals, as the name suggest are back ups to prevent extrusion in rubber o-ring sealing systems.It is also available with multiple shapes and sizes that can help your work hassle-free. It is a common phenomenon for rubber o-rings to extrude especially with present day fluid systems that are a combination of high pressures and high temperatures. And this is a situation where the Teflon backup rings play a significant role in preventing o-ring extrusion. Among the list of major qualities of these seals would be the surprisingly reduce frictional co-efficiency, which infact could be the lowest among any other type of sealing aid.
As a kind of sealing material, teflon is applied by different ways. The good corrosion resistance, stable physical property and temperature endurance make contribute to its excellent sealability. As a result, it is very applicable in the following industries, such as oil, chemical, electric and steel. The applicable media are also in a wide range, including water, oil, acid liquid and other chemical liquid. PTFE seals are typical applications for teflon.
These Teflon seals are ideal to be used as backup rings in aerospace applications especially in the Aerospace Standard AS-568A Uniform Numbering System. Teflon assures you of the quality of these types of seals, as they have been successfully approved by fluid systems designers for its added flexibility in size selection. These varieties are apt for use in sealing systems that are frequently subjected to severe duty cycles, or where pressures exceed 3,000 psi and temperatures are above 275 degrees Fahrenheit. A material extensively acclaimed for its low frictional co-efficient, teflon seals are widely employed in many types of engineering processes. It helps in cost reduction by enhancing the everyday living span of significant functionality constituents giving a brilliant sliding and dress in and tear resistant framework.
One of the most common types of industrial coatings in use today is teflon. The list of common applications for it is virtually endless, although it's important to realize that not all kinds of seals may necessarily be the best option for all your sealing solutions. Before selecting a teflon seal and coatings, you should learn as much as you can about the history and development of this type of coating.There are numerous industries that make use of PTFE for sealing purposes. Teflon sealing products also give a long lasting valve seals thanks to its acid and heat resistance properties. Because of to its vital properties, the seals locate use in parts wherever other materials aren't ample or appropriate.

Rod Seals
Seals have been used since ancient times and have evolved into a wide variety of shapes and materials.Rotary Shaft Seals
The rotary shaft seal is used for excluding dirt, dust, water or other particles, while retaining lubricant in rotary shaft equipment. It was developed as a means of protecting bearings of rotating shafts.Integral Seals from Darcoid Norcal Seal
An integral seal is named so because it effectively integrates a stamped or machined metal or molded plastic retainer with a molded in place rubber sealing element to create an extremely versatile sealing device.
