Asahi/America Inc., of Malden, Mass., introduces low-torque AV gaskets. Available in sizes and materials including 2″ to 12″ EPDM, ½?? to 12?? in PTFE-bonded EPDM, or ½?? to 10?? PVDF-bonded EPDM, these sturdy gaskets are ideal for plastic piping systems as well as metal and plastic-lined metal systems. In addition to maximum corrosion resistance, AV gaskets offer a low-torque, high-pressure sealing. At low-bolt tightening torque ratings, this sealing results in longer gasket life.
