Abstract

A tubular hydrocarbon adsorption trap includes a fuel vapor permeable porous media sheet which is circularly wrapped around to form a circumferentially closed elongated tubular body having at least one interior chamber in which the hydrocarbon vapor adsorbent media is arranged. Opposing longitudinal edges of the wrapped media sheet are secured by ultrasonic welding or other means to securely close the circumference of the tubular body. The tubular body is closed on the top and bottom longitudinal edges to retain hydrocarbon vapor adsorbent media within. A method of manufacturing the tubular hydrocarbon adsorption trap is also disclosed.
