Turcon® Variseal®
Variseal® are effective in a wide range of applications. They are chosen when higher resistance to chemical media is required, if the seal is required to operate in extremes of temperature and/or where good extrusion and compression characteristics are needed.
Characteristics
Turcon® Variseal® designs have three main characteristics:
- Application-specific U-shaped seal profile
- Spring geometry suited to the particular application
- Proven high-performance Turcon® or Zurcon® polymers
Standard or custom geometries are available in metric, inch and intermediate sizes ranging from 2 to 3,300 mm / 0.079 to 126 inch.
Method Of Operation
All Variseal® designs included on this page have the same operating principle and differ only in their profile form and the type of metallic spring used.
The Variseal® spring supplies the load required for sealing at low pressures (Figure 1). The “U” shaped jacket allows fluid pressure to energize the sealing lips, so total sealing pressure rises with increasing operating pressure (Figure 2).
