The Teflon axial seal is a high-performance seal with a special spring. The appropriate spring force plus system fluid pressure pushes the seal lip (face) out and gently presses the sealed metal surface to generate Very good sealing effect. The actuating effect of the spring overcomes the slight eccentricity of the metal mating surface and the wear of the sealing lip while maintaining the desired sealing performance.

Teflon (PTFE) is a sealing material with excellent chemical resistance than perfluororubber and good heat resistance. It can be applied to most chemical fluids, solvents, hydraulic oils and lubricating oils. It can be used for a long time to achieve sealing performance. It uses various special springs to overcome the elasticity problem of Teflon or other high-performance rubber plastics, and has developed seals that can be replaced by static or dynamic (reciprocating or rotating motion). The temperature range can be from 300 to 30 degrees Celsius, and the spring can be used in various high temperature corrosive fluids depending on the environment.

In addition to the sealing application of high temperature corrosive environment, it is very suitable for air hydraulic cylinders because of its low sealing friction coefficient, stable sealing contact pressure, high pressure resistance, large radial yaw and groove size error. The seal replaces the U or V shape to achieve excellent sealing performance and service life. Sealing performance is not affected by insufficient lubrication at start-up, effectively reducing wear and frictional resistance. Dongguan Teflon axial seal manufacturers can display different sealing forces to meet various application requirements through the combination of different sealing materials and springs. Suitable for a small variety of seals, chemical resistance and heat resistance are far superior to the commonly used seal rubber.
