{"product_id":"manguera-de-riego-por-goteo-autocompensante","title":"Pressure-compensating drip irrigation hose","description":"\u003cp\u003eWatering perennial plantations on uneven terrain, fruit trees on slopes, or professional subsurface drip irrigation (SDI) projects —where a standard hose delivers uneven flow and clogs from soil suction— requires a pressure-compensating drip hose with a silicone diaphragm and integrated anti-drain and anti-siphon mechanisms. This pressure-compensating drip irrigation hose —also known as \u003cstrong\u003ePC drip line\u003c\/strong\u003e, heavy-wall PC hose, or thick-walled PC tubing— is manufactured by Gardese from LDPE, 16 mm diameter and 1 mm thick (4000 gauge), with integrated PC emitters (1.6 L\/h flow rate, maximum deviation 7%), 0.14 bar anti-drain threshold, in two spacings (30 and 50 cm), in 500 m rolls, designed for professional precision agriculture, permanent plantations, and subsurface irrigation projects.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniform PC flow with maximum 7% deviation:\u003c\/strong\u003e the pressure-compensating system with a silicone diaphragm holds flow practically constant across the operating pressure range, equalizing the dose at every plant —an audited requirement for professional fertigation and agro-export with agronomic auditing.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-drain (ND) threshold of 0.14 bar (2.03 psi):\u003c\/strong\u003e the emitter closes automatically when pressure drops below this threshold, keeping the line full between cycles so the next pulse starts with every emitter discharging from the first second —decisive for efficient pulse irrigation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-siphon (AS) mechanism for SDI:\u003c\/strong\u003e prevents soil particles from being sucked through the emitter when the system shuts down, an essential condition for buried subsurface drip irrigation, where a conventional hose is ruined by root and sand suction.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum clogging resistance:\u003c\/strong\u003e inlet filter with anti-drain barrier, high-grade technical silicone diaphragm, and wide-passage labyrinth with dynamic self-cleaning, which significantly extends emitter lifespan compared with flat drip tape.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeavy-wall thickness (1 mm, 4000 gauge):\u003c\/strong\u003e calibrated for multi-season use (several years) with mechanical resistance to occasional agricultural equipment passage and intense Caribbean sun exposure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical applications and uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePerennial plantations on uneven terrain: citrus, mango, avocado, papaya, palm, cocoa on non-flat plots.\u003c\/li\u003e\n  \u003cli\u003eBuried subsurface drip irrigation (SDI) for fruit trees and crops where the system remains underground for years.\u003c\/li\u003e\n  \u003cli\u003ePrecision fertigation with short, frequent pulse irrigation in intensive agriculture.\u003c\/li\u003e\n  \u003cli\u003eProfessional residential landscaping with garden borders, decorative rows, and sloped garden areas.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and durability\u003c\/h3\u003e\n\u003cp\u003eAn economical pressure-compensating hose fails on two counts: the compensation diaphragm is made of low-grade silicone (losing elasticity within months and ceasing to compensate flow), and it lacks reliable AS and ND mechanisms (allowing soil suction and line drainage between cycles). Gardese uses a technical silicone diaphragm with maximum 7% deviation and integrated ND\/AS mechanisms, which separates a true PC hose built for professional fertigation from a hose labeled “PC” that does not actually compensate in practice.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color: #F3F6F3; padding: clamp(14px, 4vw, 18px); margin-top: 20px; font-size: 0.9em; color: #555555; border-radius: 8px;\"\u003e\n  \u003cstrong style=\"color: #006902;\"\u003eAlso known as:\u003c\/strong\u003e\n  \u003cstrong\u003eTechnical:\u003c\/strong\u003e PC drip line, pressure-compensating drip hose, pressure-compensated dripline, heavy-wall PC dripline, PC tubing with AS and ND.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e manguera PC, manguera de goteo autocompensante, manguera para pendientes, dripline PC.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e pressure compensating dripline (USA), PC drip line (USA), manguera autocompensante (LATAM), manguera PC (LATAM), poliducto autocompensante (MX), tubo de goteo PC (ES).\n\u003c\/div\u003e","brand":"GARDESE","offers":[{"title":"16 mm (5\/8 in) in diameter and 1 mm (Gauge 4000) thick \/ 30 cm (12 in) between drippers and 1.6 L\/h (0.35 gal\/h) flow rate \/ 500 m (1640 ft) long roll","offer_id":52744496152904,"sku":"967456","price":58500.0,"currency_code":"DOP","in_stock":false},{"title":"16 mm (5\/8 in) in diameter and 1 mm (Gauge 4000) thick \/ 50 cm (20 in) between drippers and 1.6 L\/h (0.35 gal\/h) flow rate \/ 500 m (1640 ft) long roll","offer_id":52744498676040,"sku":"945623","price":55500.0,"currency_code":"DOP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/manguera-riego-goteo-autocompensante-pc.png?v=1778208592","url":"https:\/\/dodom.com\/en\/products\/pressure-compensating-drip-irrigation-hose","provider":"Dodom","version":"1.0","type":"link"}
