PSI LineBacker® Sealing Gaskets utilize a patented rectangular sealing element, referred to as a “quad” ring, in combination with a unique groove design to effectively seal and isolate flanges of all types. This unique design provides elastic memory. Materials such as polyimide, TFE (Teflon) and vinyl may be used as sealing elements, which dramatically increases the options available for matching gasket materials to service and environmental conditions. A much broader range of retainer material/seal element combinations may therefore be used for excellent temperature and chemical range compatibility.
