Spring energized PTFE lip seal

 

Spring energized seal is a spring-energized U-cup that uses a variety of jacket profiles, spring types and materials in rod and piston, face and rotary seal configurations. They are used when elastomeric seals fail to meet temperature range, chemical resistance or friction requirements.

 

Spring loaded seal consists of variety of jacket profiles and spring types. Spring energized seals can achieve the sealing effect compensation under different pressure conditions by spring energizer. The spring energizes the seal and supplies all of the load needed for sealing when the media pressure is too low to fully actuate the lips.

 
Jacket profiles are made from PTFE and other high performance polymers. It is especially suitable for static sealing and slow reciprocating motion. Spring types are available in corrosion-resistant Stainless steel, Elgiloy and Hastelloy.
