The DS 151 model is a single-acting seal, energized by a helical spring that provides greater sealing tension than U or V springs, thus improving sealing against liquids and gases. The part is designed with an extended heel for improved extrusion behavior. The beveled working lip has a scraping and cleaning effect in abrasive or viscous media.
- Superior sealing, both in gases and liquids.
- Working lip with cleaning edge.
- Greater resistance to extrusion.
It can be machined in different formulations of PTFE with additives, Virgin PTFE and even in UHMW-PE for cryogenics. See materials section.
