Product Description

Product description

Spring energized seals encompass a variety of products that that can be customized to operate in a broader range of applications than any other seal product available. This is possible due to the availability of seal jacket materials and configurations in combination with spring loads, spring materials and spring sizes. Commonly, spring energized seals are called upon to retrofit applications where traditional seal products such as O-rings, U-cups and rubber lip seals fail due to issues of chemical compatibility, pressure, temperature, friction or high speed dynamics. 

Main properties 

. excellent low temperature resistant
. Good mechanical property
. Low coefficient of liner expansion
.Good dimensional stability
. Good penetration function

Product application

It is widely used for seals in the condition of low temperature with high pressure(gas, liquid nitrogen, liquid oxygen ect) ,semiconductor, chemical, pharmaceutical,aerospace and other relevant sealing area.

The jackets are precision machined from PTFE, filled PTFE composites and other high-performance polymers with temnperature range from cryogenic to 280 ºC.We have a variety of energy storage spring for choose, each with characteristics that meet specific requirements.
