Spring Seal/ spring energized seal/ Variseal/PTFE

Spring Seal/ spring energized seal/ Variseal is a U-type Teflon built-in special spring high-performance seal with appropriate spring force plus system fluid pressure to push out the sealing lip (face) Gently press the sealed metal surface to create a 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 refrigerant to 300 ° C, pressure from vacuum to ultra-high pressure 700 kg moving speed up to 20m / s, and the spring can be used in different environments, stainless steel, Elgiloy Hastelloy, etc., so it can be applied to a variety of high temperature corrosive fluids occasion.

The universal plug seal can be made according to the AS 568A standard O-ring groove (such as radial shaft seal, piston seal, axial surface seal, etc.), completely replacing the general O-ring, because it has no swelling, it can be long-term Maintain good sealing performance. For example, mechanical seals used in high-temperature corrosive environments of petrochemical processes, the most common causes of leakage, in addition to the uneven wear of the slip ring, the deterioration of the O-ring is also the main cause, the use of HiPerSeal can completely improve the rubber softening, swelling, surface Problems such as roughening and wear, thus greatly increasing the service life of the mechanical shaft seal.

It is suitable for sealing and static sealing. In addition to the sealing application of the above high temperature corrosive environment, it has a low friction coefficient of the sealing lip, stable sealing contact pressure, high pressure resistance, and allows for a large radial run-out. And the groove size error, it is very suitable for the seal of the empty hydraulic cylinder, replacing the U-shaped or V-shaped pressing to obtain excellent sealing performance and service life.
