Trelleborg Double Delta® combines the flexibility and response of O-Rings with the wear and friction characteristics of the Turcon® materials in dynamic applications. The double acting performance of the seal follows from the symmetrical cross section which allows 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.

Material Information for the product(s) on this page
V7
Colour:
Green
Basic Material:
FKM
Commercial Description:
A 70 durometer FKM. FKM is an elastomer material known especially for its non-flammability, low gas permeability and excellent resistance to ozone, weathering, and ageing. The operating temperatures of the fluorocarbon rubber range between -20 °C and +200 °C (for a short period of time up to +230 °C). FKM is also often used with mineral based oils and greases at high temperatures. Used as an energizer in T46V and M12V
T46
Colour:
Greyish to Dark Brown
Basic Material:
PTFE
Filler:
Virgin PTFE compounded with Turcon® and bronze
Commercial Description:
Turcon® T46 is a blend of PTFE, bronze, and a proprietary Turcon® filler and is backed by years of time-tested performance and offers a balance of performance and cost. This material has a high extrusion resistance and has very good wear properties. For medium to heavy applications with reciprocating movements in mineral oils and other media with good lubrication. Used in article numbers ending in T46N and T46V.
