• Elastic seal, which is energised by the deformation of the seal flanges towards the seal centreline. This deformation is governed by the groove and seal geometries.

• The seal will be pressure energised when subjected to pressure either from the inside or the outside.

• The HX seal works equally well both directions and is therefore the best choice when also large external pressures can occur (recommended for subsea use).

• A robust seal used in the most demanding applications.

• No practical limit for pressure that can be taken.
