　　While similar to Vee Packings, the WV style provides sealing properties that are largely independent of stack packing pressure. The WV is designed so that it will provide a multiple lip hydraulic seal in a fixed gland depth packing. Because of the design of the WV packing, te lips of each ring are free to flex when in a nested stack so each lip automatically reacts to fluid or air pressure, providing a better seal in a given packing space. There is no compression adjustment required during the seal life.

　　Since the WV Packing is a multiple lip hydraulic seal, it is recommended over a single lip seal for applications where side loading is a factor. The multiple lip also provides extra stability. If one seal fails, there will be another seal to serve as back-up.

　　There is an interference built into both the I.D. lips and the O.D. lips so that there will be sealing capabilities at low pressure.
