PTFE products
PTFE products are commonly found in a number of different applications and are particularly popular because of their unique set of properties, which includes resistance to both water and oil, and an extremely low coefficient of friction. Moreover, the material’s heat and chemical resistance coupled with its fairly high strength makes it both durable and dependable.
PTFE SPGO seal is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
In the construction industry, SPGO is one of the most commonly used PTFE combined seals applied in hydraulic cylinder. It has excellent dynamic and static sealing effect.
PTFE SPGO piston seal can be used for hole and shaft, but its sealing effect is the same. According to its own deformation, it produces high initial contact stress on the sealing surface to prevent the liquid leakage. When the hydraulic cylinder works, the pressure liquid begins to squeeze the square seal ring to the greatest extent through the elastic deformation of the O-ring, so that it is close to the sealing surface, resulting in a high additional contact stress that increases with the increase of the pressure of the pressure liquid, and together with the initial contact stress to stop the leakage of the pressure liquid.
PTFE SPNO(step seal) sealing rings are designed to restrict oil flow by eliminating the straight path of leakage. This helps to prevent leaks and ensure that the cylinder operates smoothly and efficiently. These rings are available in several side-face and coating options, and they meet DIN and JIS standards. If you are looking for a reliable sealing solution for non-critical applications, step seal sealing rings may be a good choice.
Fundamentals of PTFE SPNO(Step Seal) Sealing Rings
If you’re looking for a reliable solution for non-critical sealing applications, PTFE SPNO(step seal) sealing rings might be the right choice for you. These sealing rings are designed to restrict oil flow by eliminating the straight path of leakage.
PTFE SPNO(step seal) sealing rings are available in several side-face and coating options, meeting DIN and JIS standards. They are commonly used in piston and hydraulic systems, as well as gearboxes and pumps.
One of the key advantages of PTFE SPNO( step seal) sealing rings is their exceptional reliability. They are designed to withstand harsh operating conditions and offer long service life. Additionally, they are easy to install and require minimal maintenance.
PTFE products are commonly found in a number of different applications and are particularly popular because of their unique set of properties, which includes resistance to both water and oil, and an extremely low coefficient of friction. Moreover, the material’s heat and chemical resistance coupled with its fairly high strength makes it both durable and dependable.
These PTFE backup rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and many acids. Use them to extend the life of your O-rings and improve their performance in high-pressure applications.
PTFE products are non-toxic, odorless and highly transparent. They are soft, elastic, resistant to kinking and deformation, and do not crack. They can withstand both low and high temperatures, have a long service life, and possess high tear resistance. When stored at room temperature, they do not turn yellow, bloom or fade. When left in water for a long time, they do not produce scale or peculiar smells. Therefore, they are suitable for sealing in the food industry.
PTFE (Polytetrafluoroethylene) Stainless Steel Oil Seals are engineered to provide exceptional sealing performance in a variety of industrial applications. These seals combine the chemical resistance and low friction of PTFE with the strength and durability of stainless steel, making them ideal for environments that demand both reliability and longevity.
PTFE Stainless Steel Oil Seals are available in the following configurations: single-lip, double-lip, triple-lip, and four-lip. The lip orientation can be forward, reverse, or a combination of both forward and reverse.
The lip portion is made of PTFE composite material, which has obtained FDA environmental certification—this significantly enhances the wear resistance and fatigue resistance of the sealing lip. The metal case (or “skeleton”) is constructed from 304/316 stainless steel, which offers excellent corrosion resistance.
PTFE is a material that is well-known due to its outstanding resistance to chemical attack and its low-friction properties. flexible fluoropolymer, which is great for sealing jobs with a great deal of work. This unique molecular design of PTFE offers an exceptional resistance to chemicals and temperatures and environmental elements. This makes it the ideal material to use in critical industrial processes.
