TURCON DOUBLE DELTA

Turcon Double Delta is an rubber energised plastic faced seal. The seal is designed to expand and improve the service parameters of O-Rings and is installed in existing O-Ring grooves.

Double Delta combines the flexibility and response of O-Rings with the wear and friction characteristics of the Turcon materials in dynamic applications.

The figures below shows the cross section of the Double Delta. 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.

Notches

Turcon Double Delta is as standard supplied without radial notches, as the thin radial section of the seal gives good response to pressure variations.

For diameters from 8 mm notches on both sides are optional. These ensure direct pressurizing of the seal under all operating conditions.

Advantages

– Compact groove dimensions and simple installation
– Low friction without stick-slip
– Resistance against wear and extrusion
– Rod seals available for all diameters from 2 to 999.9 mm
– Standard cross sections cover AS 568A and important metric O-Rings, other cross sections available on request.
– Fits also groove dimensions per MIL-G-5514F

Application Examples

The Turcon Double Delta is preferably used as a double acting seal for hydraulic and pneumatic equipment in sectors such as:

  • Machine tools
  • Handling devices
  • Manipulators
  • Valves
  • Chemical process equipments

It is particular recommended for light duty and small diameter applications.

Technical Data

Operating conditions

Pressure: Up to 35 MPa
Velocity: Up to 15 m/s
Temperature: -45_C to +200_C (according to O-Ring material)

others according to O-Ring material.

Important Note:

The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value.

Special Application:

Short stroke movements, poor lubricating fluids and
soft mating surfaces.
Turcon seal: Turcon T24

Energiser: O-Ring NBR 70 shore A or FKM 70 shore A (depending on the temp.)

For low friction requirement in dynamic hydraulic components with good lubricating medium:

Turcon seal: Turcon T05

Energiser: O-Ring NBR 70 shore A or FKM 70 shore A (depending on the temp.

Special Application:

Short stroke movements, poor lubricating fluids and
soft mating surfaces.

Turcon seal: Turcon T24
Energiser: O-Ring NBR 70 shore A or FKM 70 shore A (depending on the temp.)

For low friction requirement in dynamic hydraulic components with good lubricating medium:
