Expanded PTFE round rope is a round packing braided from pure expanded PTFE-tapes. It is an extremely pliable and durable valve stem packing. Made of pure expanded PTFE, it has excellent chemical and thermal resistance, as well as an exceptionally low level of friction and adhesion. Although predominately a valve packing, AP2408 can be used as a static seal in many different areas. It can also be used in connection with most liquid and gaseous substances, including oxygen. Because of the suppleness of the pure expanded PTFE-material, AP2408 can be installed in spiral form - this reduces installation time. When compressed, the spiral becomes a solid, impervious and extremely durable PTFE-sleeve. The low coefficient of friction facilitates easy valve stem movement. The application is designed for valves, pharmaceuticals, paper mils, fibre plants where high purity and corrosion resistance is required.
