Turcon® Variseal® MC

Turcon® Variseal® MC

  • Good static and semi-dynamic sealing effect
  • Reduced friction under high loads
  • Almost universal chemical compatibility
  • Permanent elasticity unaffected by contact with chemicals
  • Available with anti-extrusion back-up rings for service in extreme conditions where single or double extrusion gaps are present.
  • Withstands aggressive and abrasive process media
  • Unlimited shelf life
  • Compact form and single piece installation, ideal for replacing multi-piece packing and sealing systems
  • No external preload required. Resistant to compression set and the need for re-tightening
  • Special sizes and geometries available

The Turcon® Variseal® MC from Trelleborg Sealing Solutions has been developed to replace multiple chevron seals or V-stack type products in subsea valve stems requiring a high-integrity sealing capability. It includes a series of single-acting spring-energized seals housed within a U-shaped Turcon® polytetrafluoroethylene (PTFE) based material seal profile. The unique single-piece design significantly improves sealing integrity and leak tightness in high-pressure applications by providing higher contact force across multiple seal hardware interfaces.

Turcon® Variseal® MC has three main design characteristics:

  • Application specific U-shaped seal profile with multiple sealing points
  • Multiple springs available in NACE approved materials
  • Proven high-performance Turcon® or Zurcon® polymers, including NORSOK approved grades
