Ptfe seals manufacturer in China? We can design the suitable spring energized seals for your application. Our oil seals have TC, TB, SC, DC, TCV and so on. Looking forward to supply the best seals for you.(O Ring Manufacturers & Hydraulic Oil Seal Manufacturers). DMS SEALS, the seals manufacturer, was founded in 2008. DMS started by manufacturing filled PTFE seals, including bronze filled PTFE, carbon filled PTFE, graphite PTFE, MoS2 filled PTFE, and glass filled PTFE. We now also produce O-rings made of NBR, FKM, silicone, EPDM, FFKM. Read even more info on o ring supplier.
The O-ring of DMS SEALS is often used in hydraulic and pneumatic transmission systems and has wide applications. It can be used for both static and reciprocating seals. Moreover, it can also be used in rotary sealing systems. The O-ring can be installed in a groove with a rectangular cross section on the outer or inner circle, achieving a good sealing effect. It has many advantages compared with other types of sealing rings. Its compact structure makes it easy to assemble and disassemble. Moreover, its dynamic frictional resistance is relatively small, and a single piece of O-ring can achieve sealing performance in both directions.
It can maintain stable performance after prolonged exposure to various corrosive compounds. Due to its lack of polarity, low unsaturation, and high chemical stability, our gasket has high resistance to various polar chemicals such as alcohols, acids (acetic acid, hydrochloric acid, etc.), strong base (sodium hydroxide, oxidant, hydrogen peroxide), detergents, animal and vegetable oils, ketones and certain esters. It is designed to have excellent aging resistance and excellent resistance to compression set and compression stress relaxation. Therefore, our gasket has significant advantages over other conventional gaskets. Its excellent materials and manufacturing process enables it to achieve effective sealing when exposed to corrosive chemicals, friction, high temperatures or very low temperatures. At the same time, it is easy to install and has industry-leading creep resistance, which saves users a lot of time and cost and increases productivity.
Since the scraper seal is made of the special material, PTFE, it has an impurity immersion function. Therefore, when combined with the piston rod seal and the metal bushing, it can prevent damage to the piston rod and prevent the accumulation of oil pressure. It has a diameter range of 3-1600mm and a temperature range of -30°C + 200°C. The wiper scraper seal can operate at speeds of up to 5 m/s. It has high wear resistance, tear resistance, low-temperature resistance and good strength. Our wiper seals can be used in combination with piston seals and anti-wear rings to prevent oil in the cylinder from being mixed with foreign matter, which causes damage to the working seal. It is especially suitable for piston rods with a large diameter. Moreover, it has a wide range of applications, such as agricultural machinery, injection moulding machines, forklifts, cranes and so on.
Gasket sealing mechanism: The function of the gasket is caused by the blocking effect on the internal medium formed by the contact pressure of the sealing material on the joint surface and the elastic restoring force to the external tightening force. Classification and structure of gaskets: Gaskets are divided into three categories: non-metallic gaskets, non-metallic and metal combined gaskets and metal gaskets. The common materials are rubber, leather, asbestos board, cork, PTFE, tinplate, steel, aluminum, copper and stainless steel.
Good sealing performance: Because the system works outdoors, there is no leakage oil recovery system, and the working medium will directly pollute the environment after leakage, so external leakage requirements are strict. At the same time, for the requirements of hydraulic oil heating control, pressure maintaining or maintaining position, the internal leakage requirements are also very strict. High pressure: The working pressure of the hydraulic system is high, usually above 20MPa, and the highest is about 40Mpa, which is higher than the general industrial hydraulic system pressure, so the sealing pressure resistance requirements are high.
Supplied in rolls or open loops. The open ring can be directly installed and used, but it must be cut when the roll is used, and the cutting length must be calculated in advance: there can only be one opening, the opening form is an oblique 45° opening, and the opening distance is about 3-15mm, or the diameter of the guide ring 3-5% of . Under normal circumstances, the openings are oblique openings. Straight openings or zigzag openings are rare and have specific uses and purposes. There are two purposes for the opening. The first is to facilitate installation. If it is not opened, it is an integral ring, which is difficult to install or impossible to install, so it must be opened. Secondly, the opening and a certain opening distance are reserved to facilitate the automatic coordination of volume changes. Otherwise, the movement may be stuck or the moving parts may be pulled due to the excessive expansion of the guide belt under certain conditions. Coiled ones are relatively cheap, and the same coil can be used to make guide rings of different sizes. See more details at dmsseals.com.
