The ASME B16.20 Ring Type Joint (RTJ) Gasket is a precision-engineered sealing solution designed for extreme-pressure applications. Crafted from soft iron, this 8-inch (DN200) gasket conforms to ASME B16.20 standards and is rated for Class 2500 LB (PN420) pressure conditions. The ring-type joint design creates a reliable metal-to-metal seal when compressed between mating flanges, with the soft iron material deforming to fill microscopic surface irregularities for exceptional leak-tight performance.
