DR 118 BB

The DR 118 BB model is a seal for static or dynamic applications of low rotation, consisting of a double PTFE collar (with loads) and a metal spring that tensions the collar and maintains its geometry around its perimeter. The lips of the collars have a protrusion on the inside to hold the spring in place.
The seal is axially deformable and is used in the internal pressurization of front rotating systems, such as loading arms for fuels, oil, liquefied gases...
- U-shaped, V-shaped or helical springs.
