DR 119

Model DR 119 is a seal for static or dynamic low rotation applications, consisting of a PTFE collar (with loads) and a metallic spring that tensions the collar and maintains its geometry around its entire perimeter. Both lips of the collar have a protrusion on the inside to hold the spring in place.
The seal deforms axially and is used in the external pressurization of caps or front rotating systems, such as fuel loading arms.
- U-shaped, V-shaped or helical springs.
- Part free of Stick-slip effect.
- Double spring retention.
The slip ring can be machined in various PTFE formulations.
