With the unique quad ring design, elastic memory is provided for elastomers not normally associated with this characteristic. Materials such as PTFE may therefore be used as sealing elements, dramatically increasing the ability to match gasket materials to service 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 a positive seal without excessive bolt loads - as are often required with flat gaskets. Features:- Eliminates flange leaks Guards against blowouts Usable with virtually any type of flange Matches gasket materials to service conditions Lowest possible clamp and compressive load Increases gasket life Insulating version is both a positive seal and a superior insulator Accessories:- NITRILE SEALS,MYLAR SLEEVES,G10 WASHERS,ZPS WASHERS, Type F
