extended product description
Teekay Axiflex (non axially restrained)
The Axiflex with its pronounced multi-chamber sealing lips is suitable for mounting on already
attached / fixed pipes and allows expansion or displacement of the pipe in the coupling.
The sealing lips press against the surface. As the line pressure increases, so does the contact
pressure of the seal. Thus, a constant seal is guaranteed in each released pressure level.
The listed dimensions are guides to the most common sizes. Couplings of other diameters can
also be made.
|Type I||AISI 304/ 1.4301||-||C-Steel, PTFE coated|
|Type II||AISI 304/ 1.4301||-||AISI 316/ 316L|
|Type IV||AISI 316L/ 1.4404||-||AISI 316/ 316L|
|Type V*||axially restrained C-Steel||Rilsan/ PVC/ Epoxy||C-Steel, PTFE coated|
|Type VI*||axially restrained C-Steel||Rilsan/ PVC/ Epoxy||AISI 316/ 316L|
* Application for Type V and Type VI at high pressures and aggressive soil conditions
Housing and seal also available in material 1.4462 or 1.4539 on request.
|Sealing material||Temperature range|
|EPDM||-40°C to +100°C|

Due to the minimum distance between the pipe ends (see installation instructions), the rubber
can be sucked into the pipe under negative pressure. To prevent this, a vacuum ring can optionally
