DK 219

Model DK 219 is a single acting energized joint with a U-shaped spring. It is a profile recommended for dynamic applications. The part is designed with an extended heel for improved extrusion behavior. The beveled design of the outer lip provides a scraping and cleaning effect of the sliding zone. The ribbing on the inner diameter allows the part to be fixed in its housing.
- Increased extrusion resistance in high pressure and temperature services.
- Outer lip with cleaning edge.
- Inner fixing ribbing.
It can be machined in different formulations of PTFE with additives, Virgin PTFE and even in UHMW-PE for cryogenics. See materials section.
