DOUBLE PTFE TTV O-RING. double PTFE wrapped Viton core.

 We have the privilege to offer our clients a wide array of TTV 'O' Rings (double PTFE wrapped Viton core). These rings combine the elasticity of Viton with the chemical resistance of PTFE. Moreover, we make sure that the outer joint of the TTV 'O' ring is faced away from the assembly direction.

The O-Ring marks a strikingly simple form and reliable function. The sealing action of the O-Ring is formed by the deformation of its cross-section d2 in a groove.

Thereby, the sealing gap at the groove base and the contact or sealing surface is sealed. As a result a surface pressure is generated, which makes the sealing effect possible. The maximum deformation of the O-Ring cross section depends mainly on the depth of the groove. With the right groove design and material selection, a dynamic or static seal can then be employed within the temperature limits of the material.

ttv O-Rings are manufactured and controlled in accordance to DIN 3601 (formerly 3771). They are produced seamlessly in a heated injection or compression mould by vulcanization. As for the material variations of elastomer materials are used.

The designation of the O-Ring is composed of three elements:

» d1 = Dimensions of the inner diameter (mm)

» d2 = Cord thickness (mm)

» Material designation and its hardness (elasticity)
