Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.

Spring type:
V Springs
V springs also referred to as cantilever, U or meander springs offer a light to medium load. This type of spring is intended for use in dynamic applications of rotary or linear motion and offers a relatively large amount of defection. V springs are also used in static applications where large spring defection is required i.e. a large tolerance on the groove dimensions, expansion/contraction/misalignment etc. Standard materials for V springs are stainless steel and Elgiloy®. V springs allow for an extremely fexible and wide operating range of seal. The load curve of a V spring is progressive until sudden failure and permanent deformation.
Canted Coil Springs
Canted coil springs are made from a round wire coil that is formed so the coils lay over at an angle. This results in a load/defection curve which is fat rather than progressive and very well suited to dynamic applications which are friction sensitive. Like the V spring, the canted coil spring is designed for use in dynamic applications of rotary and linear motion and static applications where a greater tolerance or defection must be accommodated. Standard materials are stainless steel and Alloy C-276.
Helical Springs
Helical springs are coil springs made from fat tape which is would into a helix shaped coil. Helical springs offer a very limited amount of defection versus a very high load displaying an instantly and dramatically progressive load/defection curve. Helical springs are intended for use in static applications or in certain circumstances they can be used for very slow or infrequent dynamic applications providing higher friction is acceptable. Helical springs are ideal for high pressure or vacuum applications where precise tolerances can be adhered to on the groove detail. Helical springs should also be the frst choice for cryogenic applications. For the most extreme service a double wall heat treated option can be supplied ensuring the maximum amount of sealing force and ductility of material at extreme cryogenic temperatures.
