Highlights

What sets Visio apart

Technical tightness

Exceeds TA Luft and VDI 2290 requirements in combination with a leakage verification according to EN 1591-1, even with lower-grade bolts.

No retightening

The resilient design makes retightening the flanges unnecessary, even with strong pressure and temperature fluctuations.

Versatile

For smooth sealing faces, tongue and groove, male and female facings and apparatus flanges with webs. Standard material 1.4571, total thickness 1.6 ± 0.1 mm.

Tested and certified

Fire-safe according to API 607, TA Luft including blow-out resistance according to VDI 2200, FDA conformity of the PTFE version.
