Spring Seal/ spring energized seal/ Variseal (U type Teflon) is a high-performance seal with a special spring inside, by the appropriate spring force plus system fluid pressure, The sealing lip (face) is pushed out and gently pressed against the sealed metal surface to produce a very good sealing effect. The actuating effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, while maintaining the desired sealing performance.

PTFE is a kind of chemical resistance than perfluorinated rubber excellent, good heat resistance sealing material, can be applied to the vast majority of chemical fluids, solvents, as well as hydraulic oil, lubricating oil, its swelling is very small so it can play a long-term sealing performance, the use of a variety of special springs to overcome the elasticity of teflon or other high-performance rubber plastics. Developed to replace most of the application of static or dynamic (reciprocating or rotating motion) seals, can be used in a variety of high-temperature corrosion fluid applications.

Pan plug sealing is suitable for both static and static, in addition to the above high temperature corrosion environment sealing applications, because of its low seal lip friction coefficient, seal contact pressure stability, high pressure resistance, allow large radial bias and groove size error, it is very suitable for air hydraulic cylinder seals, replace U or V shape packing and obtain excellent sealing performance and service life.

Product advantage:
● Can be used for reciprocating and rotating motion
