Turcon® Double Delta®

Double Delta® combines the flexibility and response of O-Rings with the wear and friction characteristics of the Turcon® materials in. The double acting performance of the seal follows from the symmetrical cross section which allow the seal to respond to pressure in both directions. Initial contact pressure is provided by radial compression of the O-Ring. When the system pressure is increased the O-Ring transforms this into additional contact pressure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions.

Basic Material
PTFE/NBR
Filler
Virgin PTFE compounded with Turcon®, mineral fibre and additives
Commercial Description
Turcon® M12 is used as a primary sealing material and paired with an NBR (N7) elastomer with O-ring energized seals. Turcon® M12 offers low friction, high wear resistance, and costs on par with standard bronze-filled compounds. NBR is used to provide good, general sealing capabilities.
