It features a dual spray nozzle with a half-circle coverage pattern, making it well suited for edges, borders, and perimeter turf areas. The unit incorporates Close-In watering technology for uniform water distribution that reduces dry spots near the head. A co-molded wiper seal protects the internal components and extends service life. A heavy-duty stainless steel spring ensures consistent, full retraction after each cycle. Licensed irrigators and landscape contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis sprinkler head is used in residential lawns, commercial turf areas, and landscape beds where half-circle coverage is required. The 4-inch pop-up height makes it appropriate for turf applications where grass height stays within standard mowing ranges. A top-adjustment screw allows the technician to reduce spray distance without removing the head or changing nozzles. Nozzle changes require no tools, which speeds up service calls and routine maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHalf-circle spray pattern provides targeted coverage along edges and borders\u003c\/li\u003e\n  \u003cli\u003eDual spray nozzle delivers uniform water distribution with Close-In watering technology\u003c\/li\u003e\n  \u003cli\u003eCo-molded wiper seal extends head life by keeping debris out of the riser seal\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty stainless steel spring ensures flush retraction after every cycle\u003c\/li\u003e\n  \u003cli\u003eTop-adjustment screw reduces spray distance without tools or disassembly\u003c\/li\u003e\n  \u003cli\u003eTool-free nozzle replacement simplifies field servicing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation sprinkler head for standard 1800 series pop-up irrigation systems using half-circle nozzle configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed irrigators or qualified landscape contractors in accordance with local irrigation codes and water authority requirements. Shut off the irrigation zone and relieve line pressure before removing or replacing the head. Ensure the riser is threaded fully and the head sits flush with the finished grade to prevent mowing damage and uneven pop-up height. Verify zone pressure falls within the rated operating range of the nozzle to maintain uniform distribution uniformity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePop-Up Height\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Half circle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Dual spray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Material\u003c\/strong\u003e: Stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.225 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RAIN BIRD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1804HDS-25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RAIN BIRD","offers":[{"title":"Default Title","offer_id":51698502926642,"sku":"1804HDS-25","price":17.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6e27212e774bd49f055536c1cd73f04.jpg?v=1788363893","url":"https:\/\/voomisupply.com\/products\/rain-bird-1804hds-25-pop-up-sprinkler-head-half-circle","provider":"Voomi Supply","version":"1.0","type":"link"}
