Product Description

Product name

High quality spring energized seal under cryogenic condition

Spring-energized seal is a spring-actuated, pressure-assisted sealing device consisting of a PTFE( or other polymer) jacket, especiallly encapsulating a corrosion-resistant energizer

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.
