When your emitters lack internal check valves, the entire lateral line drains at the lowest point every time the zone shuts down, leading to soggy soil in depressions and air pockets that delay water delivery during the next cycle. In the peak of the summer heat, these delays and inconsistencies can ruin turf or cause permanent wilt in nursery stock. With global supply chains remaining unpredictable, waiting until a system fails to secure your emitters is a risk to your project deadlines. Planning your inventory now ensures your crews stay on schedule and your clients receive the uniform growth they expect.\u003c\/p\u003e\u003cp\u003eThese Netafim self piercing emitters provide a distinct technical advantage over standard punch-in drippers by integrating a high pressure check valve. This internal mechanism holds water in the supply lines between cycles, preventing low point drainage and ensuring instantaneous watering across the entire run. This design significantly reduces labor costs during installation because the self piercing barb eliminates the need for separate hole punching tools on many polyethylene tubing types. By choosing a pressure compensating model with a 2.5 PSI shut off elevation, you provide your clients with a system that performs consistently on slopes and varying elevations, giving your firm a reputation for high quality, reliable engineering.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh grade UV resistant plastics and silicone diaphragm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlow Rate\u003c\/td\u003e\n\u003ctd\u003e1.0 Gallon Per Hour (GPH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Range\u003c\/td\u003e\n\u003ctd\u003e10 to 45 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCheck Valve Shut Off\u003c\/td\u003e\n\u003ctd\u003e2.5 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInlet Type\u003c\/td\u003e\n\u003ctd\u003eSelf piercing barb for 1\/4 inch tubing or direct to lateral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutlet Type\u003c\/td\u003e\n\u003ctd\u003eNipple for attachment of 1\/4 inch distribution tubing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor Code\u003c\/td\u003e\n\u003ctd\u003eBlack body with color coded insert\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eISO 9261 compliant for flow and performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThe Netafim pressure compensating series is available in flow rates of 0.5 GPH, 1.0 GPH, and 2.0 GPH to accommodate various soil types and plant water requirements.

While the self piercing design allows for direct entry, ensure the polyethylene tubing is warm and flexible to prevent cracking during cold weather installs. Always flush the main supply lines before installing emitters to remove debris that could bypass the internal filtration. Check local codes for backflow prevention requirements when connecting to potable water sources. If using distribution tubing on the outlet, secure the tubing to a stabilizer stake to prevent the emitter from twisting out of the lateral line over time.\u003c\/p\u003e","brand":"Netafim USA","offers":[{"title":"Default Title","offer_id":52093144498465,"sku":"21520-003828","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/netafim_21520_003828.png?v=1765470849","url":"https:\/\/asiwsupply.com\/products\/netafim-self-piercing-pressure-compensating-emitters-with-internal-check-valve-1-gph","provider":"ASIW","version":"1.0","type":"link"}
