- 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.
