An improved low volume spray device for an irrigation system comprises upper and lower separately molded plastic members that may be assembled before or after the lower member is installed on a fluid conduit. The lower member, which is secured within the conduit, is molded with a conical deflector portion that receives the main force of the liquid stream from the conduit. An upper head member snaps onto the lower member and has a peripheral series of spaced apart teeth adapted to receive liquid from the conical deflector and separate it to form a uniform spray pattern of radially directed streams. Since the main fluid force is on the conical deflector, fluid pressure cannot act to separate the upper member when in use.
