Anti-Leak Micro Irrigation Valve Nozzle Connector for Garden Sprinklers, Greenhouse & Agricultural Drip Hose - 100 Pcs

Designed for lawn and garden watering as well as irrigating trees and high-rise plants, this anti-leak valve is a practical accessory for micro irrigation systems. Inside each unit is a high-quality "O"-shaped silicone sleeve that provides strong sealing performance and a long service life. The valve operates automatically with system pressure: when pressure reaches a designated level the silicone ring moves away from the hose and the valve opens to allow water flow; at the corresponding pressure the silicone ring seats against the hose and the valve closes to stop water passage. The primary function of these fittings is to shut the nozzle and prevent water leakage.
