It features a high-efficiency (HE) nozzle that produces larger water droplets at a lower trajectory, reducing system run times by up to 35 percent compared to standard nozzles. The unit ships with a patented pressure-activated co-molded wiper seal that keeps the stem clean and extends service life. A stainless steel retraction spring and stainless steel flow-reduction screw round out the core mechanical components. Inlet size is 1\/2 inch. This head is installed by irrigation contractors and landscape professionals as part of zoned spray irrigation layouts.\u003c\/p\u003e\u003cp\u003eThe 1804HEVN15 is suited for turf and ground cover zones where water conservation and uniform coverage are priorities. The adjustable pattern covers 0 to 360 degrees, making it adaptable to corner, edge, and full-circle applications without stocking multiple fixed-pattern heads. The removable grit filter protects the nozzle orifice from debris in supply lines, which is especially useful during initial system startup or in areas with older piping. This unit is sold in a package quantity of 18, making it practical for contractors stocking multi-zone installs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-efficiency nozzle reduces run times by up to 35 percent through larger droplet size and lower spray trajectory\u003c\/li\u003e\n\u003cli\u003eAdjustable pattern from 0 to 360 degrees covers corner, strip, and full-circle zones\u003c\/li\u003e\n\u003cli\u003ePatented pressure-activated co-molded wiper seal keeps stem and body clean during retraction\u003c\/li\u003e\n\u003cli\u003eStainless steel retractable spring and stainless steel flow-reduction screw for long-term durability\u003c\/li\u003e\n\u003cli\u003eRemovable grit filter protects nozzle from particulate debris in the supply line\u003c\/li\u003e\n\u003cli\u003eEasy nozzle alignment feature simplifies pattern adjustment during installation and service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation spray head for standard 1\/2-inch threaded irrigation spray body applications in residential and commercial landscape irrigation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed irrigation contractors or qualified landscape professionals.
