Abstract
A weight component for an irrigation drop tube includes an elongated, hollow core sleeve, the core sleeve having a radially outwardly directed shoulder at one end connected to a radially outer skirt. A weight sleeve is supported at one end by the shoulder, inside the outer skirt, such that a chamber is created between the core sleeve and the weight sleeve. This chamber is at least partially filled with ballast material, and a cap closes the chamber at an opposite end of the weight sleeve.
