subject: Energized Ptfe Spring Seals Features And Applications [print this page] For the most demanding applications in industries like Oil and Gas, Fluid Handling, Medical , Food Service, Aerospace and Pharmaceuticals, it is essential to use high quality energized spring sealing. PTFE sealing is one of the best seals that are perfect to meet the temperature, frictional and chemical resistance requirements of different industrial applications.
Energized PTFE spring seals are widely used in industries for various applications that demand extreme temperature, chemical compatibility, long life and ultra-low friction performance. PTFE is one of the most popular polymers that are used to manufacture seals.
PTFE (commonly renowned as Teflon) made seals offer inert static as well as dynamic sealing for some of the most demanding industry applications. Although Teflon seals provide several advantages, but to maintain and increase its sealing forces an energizer is required.
The elastic PTFE sealing jacket is made resilient using an internal energizing spring. At low pressure, the thin sealing jacket applies load to the sealing element. With the increase in system pressure, the shaft or bore results in the seals that are highly efficient. The spring of the PTFE energized seals offer permanent resilience to the jacket of the seals.
The excellent features of PTFE spring energized seals make these the perfect sealing products for multiple industrial applications. Being chemically resistant, dry running or lubricated, low friction without stick/slip, the seals are ideal for industrial purposes. Unlimited shelf life and ability to withstand extreme pressure make these energized seals suitable for applications that demand high sealing efficiency.
Seals made up of PTFE or Teflon gain huge appreciation in industries as these offer exceptional resistance to corrosion. Also, the seals have lowest coefficient of friction as compared to all the other sealing materials.
Unlike elastomeric sealing materials such as Nitrile, Polyurethane, Rubber and Viton, PTFE offers little or zero memory after compression as it is made up of plastic. As a result of it, Teflon seals require an energizing element that is usually made of metal spring or rubber.
PTFE Spring energized seals are used for rotating shafts as rotary seals, rod or piston sealing, static and face sealing applications. Also, such sealing is used in fluid handling, semiconductor, medical devices, military and defense, pharmaceuticals, oil & seismic transportation and food service industry.
There are reputable manufacturers that design energized spring seals of Teflon. As various factors affect the performance of seals, therefore it is essential to keep in view surface finish, hardness, spring energizer, lubrication, operating conditions, polymer jacket, spring load vs. deflection and frictional considerations.
With manufactures and suppliers of energized seals, it has become easy for industries to fulfill their sealing requirements. For your convenience, you can even search online to find out manufactures that cater to your diverse requirements of polymer seals, bushings, bearings and precision components.
However, you need to do your research work right before taking any decision. Make sure that the manufacturer is reputable and has experience to rely on. You can go through their websites and review testimonials of their recent clients. It would certainly help you to know about the image of manufacturer among other industries.
When seeking manufactures of energized PFTE spring seals, make sure that the products offered by them are of high-quality. Go for manufactures that offer products at competitive prices. You can even compare seals and other products on the basis of quality and prices.
