The style EQFG spiral wound gaskets are built to ASME B16.20 specifications. Style EQFG gaskets have the inherent strength, resiliency and blowout resistance of spiral wound gaskets, yet require low bolt load for seating. They are manufactured with high purity flexible graphite filler for optimum sealability, and are available for the full range of standard Pound Classes, as well as other non-standard low pressure flanges.
