The Double Studded Adapter (DSA) is a sophisticated flange featuring a through bore, dual ring grooves, and bolt hole configurations on each face, complemented by tapped end studs and nuts. Unlike traditional spacer flanges, the DSA uniquely accommodates variations in size and pressure ratings on each side, making it indispensable for connecting disparate nominal sizes, pressure ratings, and configurations.
