Turcon® Variseal®

Low Friction, Self Lubricating and Chemically Inert


Key Benefits:

  • For static, dynamic and rotary applications
  • Used as a rod or piston seal or wiper to minimize contamination
  • Turcon® PTFE based materials provide the lowest coefficient-of-friction available (.04 to .08)
  • Operating temperatures range from -253 °C to +300 °C/ -423 °F to +572 °F
  • Chemically inert and self lubricating for cleaner operation
  • Three spring designs to customize load deflection characteristics

Typical Healthcare & Medical Applications:

Diagnostic & lab equipment such as syringe pumps, HPLC, immunoassay and chemistry analyzers. Powered surgical hand pieces such as bone drills, and oscillatory saws in cranial, ENT and large bone orthopedic applications. Pharmaceutical and biotech filling equipment as well as cryogenic and oxygen applications.

Materials Specific to Healthcare & Medical

PTFE, UHMWPE and Polyesters are typically used as the seal jacket material for most life sciences applications. Spring energizers are available in three materials: stainless steel, Hastelloy® and Elgiloy®. The seals can be made using materials compliant with FDA CFR177.2600, 3-A, USP Class VI, Cytotoxicity (USP 87), NSF, KTW, WRAS etc.

About Turcon® Variseal®

Turcon® Variseal® are used in a variety of medical, pharmaceutical and biotechnology applications, generally in reciprocating pump, cylinder or valve applications. They can also be used in rotary applications such as bone drills, swivels and valves or in static applications such as connectors or cryogenics.

The seals are comprised of two components: a jacket and energizer. The jacket seals against the mating surface and is generally made of a plastic and is usually energized by a metallic spring.

In low pressure applications, the energizer maintains seal load against the mating surface. For higher pressures, the media pressure itself can be used to maintain seal load allowing the seal to function at extremely high pressures.

We offer three types of metal spring energizer designs: slant coil, cantilever and helical. Each spring type has a different load deflection curve allowing our engineers to optimize the seal design based on the application requirements.
