Turcon® Roto Variseal® for Oil & Gas - Trelleborg

Turcon® Roto Variseal®

  • Suitable for rotary, reciprocating and static service
  • Remains tight in the groove even when subject to oscillating or helical movements
  • Low coefficient of friction
  • Protects against mechanical torsion
  • Good scraping effect
  • Stick-slip-free operating for precise control
  • High abrasion resistance and dimensional stability
  • Withstands rapid changes in temperature
  • Protects against mechanical torsion
  • Excellent resistance to aging
  • Unlimited shelf life
  • Unidirectional seal
  • Anti-rotation flange secures seal in hardware

Turcon® Roto Variseal® is excellent in rotary, reciprocating and static applications, when there is a need to lock the seal in the groove. The standard Variseal® for rotary applications, Turcon® Roto Variseal® is a single acting seal consisting of a U-shaped jacket and a V-shaped corrosion resistant spring.

Turcon® Roto Variseal® has a flanged heel, which prevents the seal from rotating in the groove and a short heavy dynamic lip that reduces friction. This gives a long service life and good scraping ability, even in media of high viscosity.
