Ptfe seals provider 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. Discover additional info at seals manufacturer.

The O-ring seal, which is also called shaft seal, is noted for a reasonable compression and stretch rate to achieve a good sealing effect. It will not leak when it is sealed statically. At the same time, the O-ring size is properly matched to the groove size. The structure is simple and its installation is very close to the machine. Its most prominent advantage is its self-sealing effect, eliminating the need for periodic adjustments. We guarantee that the size and mounting grooves of all our O-rings are standardized, so they are cost-effective and easy to maintain. They have low frictional resistance and are suitable for occasions where the pressure is often alternating.

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.

Our piston seals are designed to provide excellent leak control. We guarantee that it can perfectly meet the user’s requirements for low friction, compactness, precise configuration and simple installation. It is designed for fluid power applications. It is made of compound materials with high performance, which guarantees excellent wear resistance and excellent extrusion resistance for the seal. It is designed to be suitable for almost all fluid media and is highly resistant to oxidation and corrosion. It has excellent dynamic and static sealing performance and can even work under dusty industrial environments. Moreover, it has strong adaptability to various working conditions and can adapt to a fast, high-pressure working environment. At the same time, it has unparalleled performance in extreme temperature environments.

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.

Construction machinery sealing system requirements: High and low temperature resistance Because of continuous work for a long time, if it is outdoors in summer, the hydraulic oil temperature of the machine may exceed 100°C, which requires the seal to be resistant to high temperature. If it is outdoors in winter, the temperature may be around -40°C when it is just turned on, and the seals are required to be resistant to low temperatures. Therefore, the sealing system is required to withstand a wide temperature range. The machine itself walks. Due to the limitation of volume and weight, the hydraulic oil tank is generally relatively small.

We own a number of invention patents and leading production process. The R&D teams have the ability to design and develop seals for various of complicated working condition of sealing system. We have already passed the certification of ISO 9001 and IATF 16949. We have the mature technical reserve for the solution of ultra-high temperature, ultra-high pressure, ultra-low temperature, highly corrosive and other special working condition.
