LineBacker

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. With the unique quad ring design, elastic memory is provided for elastomers not normally associated with this characteristic. Materials such as AFLAS, TFE (Teflon) and KALREZ may therefore be used as sealing elements which dramatically increases the options available for matching gasket materials to service and environmental conditions. This greater variety of materials also provides excellent temperature and chemical range compatibility. LineBacker sealing gaskets are self energizing with theoretical near zero m and y factors resulting in effecting a positive seal without excessive bolt loads required with flat gaskets.
