Our Poly Directors feature a robust BSPT male thread on one end and a high-tensile barbed connection on the other, making them the essential fitting for connecting supply lines to pumps, tanks, and solenoid valves. Designed to provide a secure, leak-resistant transition, these directors ensure that your high-pressure main lines remain intact during automated watering cycles. Built to survive the rigours of commercial fertigation rooms and the harsh Australian climate, they offer the reliability needed for long-term water distribution in both horticultural and agricultural environments.\u003c\/p\u003e\n  \n  \u003chr\u003e\n  \n  \u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e Connecting poly pipe to water pumps, tapping into threaded tank outlets, installing master valves, and transitioning from rigid PVC manifolds to flexible lateral lines.\u003c\/p\u003e\n  \n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision BSPT Threading:\u003c\/strong\u003e Features a strong, standard 3\/4\" BSPT male thread that provides a deep, secure engagement with pumps, tap timers, and female-threaded irrigation components.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Pressure Barbed Grip:\u003c\/strong\u003e Engineered with aggressive, well-defined barbs that provide a superior mechanical \"bite\" into the poly pipe wall, preventing hose pull-out under system pressure.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIndustrial UV-Stabilisation:\u003c\/strong\u003e Manufactured from premium, weather-resistant polymers designed to withstand intense HID\/LED grow lighting and direct sunlight without becoming brittle or cracking.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChemical \u0026amp; Nutrient Stable:\u003c\/strong\u003e Built to handle the continuous flow of concentrated mineral salts and pH adjusters common in hydroponic reservoirs without corroding or leaching.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVersatile 3\/4\" Interface:\u003c\/strong\u003e The universal 3\/4\" thread size makes these directors compatible with the vast majority of standard irrigation valves, manifold outlets, and water-transfer equipment.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInstallation-Grade Reliability:\u003c\/strong\u003e Trusted by professional installers across Australia for their consistent performance in residential, commercial, and agricultural water systems.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eAvailable Sizes\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003e13mm Director x 3\/4\" (Bag of 20):\u003c\/strong\u003e The standard choice for connecting 13mm distribution lines to tap timers or small pumps.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e19mm Director x 3\/4\" (Bag of 20):\u003c\/strong\u003e The versatile \"all-rounder\" for medium-flow systems and master valve connections.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e25mm Director x 3\/4\" (Bag of 20):\u003c\/strong\u003e The professional choice for high-volume main supply lines and commercial pump-to-manifold transitions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eSpecifications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-Impact Polypropylene \/ ABS\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFitting Type:\u003c\/strong\u003e Male BSPT Thread to Barbed Hose Tail\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/4\" (Standard Australian\/British Thread)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 20 Pieces per Bag\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black (Light-Proof)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eInstallation \u0026amp; Maintenance Tips\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThread Sealing:\u003c\/strong\u003e To ensure a 100% watertight connection on the threaded end, always apply 3–5 wraps of quality PTFE (Teflon) tape in a clockwise direction before screwing the director into your pump or valve.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThermal Seating:\u003c\/strong\u003e For the tightest seal on the barbed end, dip the end of your poly pipe in hot water for 15 seconds.
