This DeatschWerks adapter converts an 8AN male flare connection to an M18x1.5 male inverted flare thread, intended to join AN-style plumbing with M18x1.5 inverted flare fittings. Use it for fluid or fuel system transitions where those exact thread sizes are required; verify thread pitch and sealing compatibility with your existing components before installation.
