Five Energizers for PTFE Spring-Energized Seals

PTFE Seals


PTFE spring-energized seals are a popular choice for engineers.  The reasons are many, including their long service life, even wear, and their ability to perform in some of the harshest environments.  They work well in extreme temperatures; can even perform well in situations where operating conditions can vary significantly.  They usually offer a low compression set, have a long shelf life, and work very well in non-lubricated applications.  The use of PTFE results in extremely low friction and excellent chemical compatibility and users can choose from a variety of spring energizers.
