Every seal manufactured at AFT Fluorotec is designed and made specifically to suit the application.
Whilst we work around typical designs and groove dimensions for much of what we do, it is not a full picture of all we do. Many of the seals we design and supply are specials – the difficult applications, the extremes, often specific to particular products and service conditions and very often oil and gas related.
AFVI / AFVE Seals
Internal and external face seals energised with a V (cantilever) spring are suitable for static and slow dynamic applications.
Spring pre-load is light to medium which keeps friction lower. Some seal defection can be tolerated without permanent deformation as the V spring allows the seal to cope with minor misalignment. The heel length of this type of seal can be increased for high pressure applications and these can also be combined with back up rings for higher pressure applications.
AFCI / AFCE Seals
Internal and external face seals energised with a tape wound helical spring suitable for static applications only.
Spring pre-load is high and these type of seals require precision in the two mating faces. The heel length of this type of seal can be increased to accommodate higher pressures and this seal profle type can also be combined with back up rings for even higher pressure applications
