Poly Directors – Heavy-Duty Threaded-to-Barb Adaptors (Bag of 20)

Poly Directors – Heavy-Duty Threaded-to-Barb Adaptors (Bag of 20)

Seamlessly bridging the gap between rigid threaded infrastructure and flexible poly piping is critical for any professional irrigation setup. 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.

Best For: Connecting poly pipe to water pumps, tapping into threaded tank outlets, installing master valves, and transitioning from rigid PVC manifolds to flexible lateral lines.

Key Features

• Precision BSPT Threading: Features a strong, standard 3/4" BSPT male thread that provides a deep, secure engagement with pumps, tap timers, and female-threaded irrigation components.
• High-Pressure Barbed Grip: Engineered with aggressive, well-defined barbs that provide a superior mechanical "bite" into the poly pipe wall, preventing hose pull-out under system pressure.
• Industrial UV-Stabilisation: Manufactured from premium, weather-resistant polymers designed to withstand intense HID/LED grow lighting and direct sunlight without becoming brittle or cracking.
• Chemical & Nutrient Stable: Built to handle the continuous flow of concentrated mineral salts and pH adjusters common in hydroponic reservoirs without corroding or leaching.
• Versatile 3/4" Interface: The universal 3/4" thread size makes these directors compatible with the vast majority of standard irrigation valves, manifold outlets, and water-transfer equipment.
• Installation-Grade Reliability: Trusted by professional installers across Australia for their consistent performance in residential, commercial, and agricultural water systems.

Available Sizes

• 13mm Director x 3/4" (Bag of 20): The standard choice for connecting 13mm distribution lines to tap timers or small pumps.
• 19mm Director x 3/4" (Bag of 20): The versatile "all-rounder" for medium-flow systems and master valve connections.
• 25mm Director x 3/4" (Bag of 20): The professional choice for high-volume main supply lines and commercial pump-to-manifold transitions.

Specifications

• Material: High-Impact Polypropylene / ABS
• Fitting Type: Male BSPT Thread to Barbed Hose Tail
• Thread Size: 3/4" (Standard Australian/British Thread)
• Quantity: 20 Pieces per Bag
• Colour: Black (Light-Proof)

Installation & Maintenance Tips

• Thread Sealing: 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.
• Thermal Seating: For the tightest seal on the barbed end, dip the end of your poly pipe in hot water for 15 seconds. Slide the pipe fully over the barbs until it hits the shoulder of the director for a "shrink-wrap" fit.
• Hose Clamps: For high-pressure applications or pump outlets, we recommend using a stainless steel ratchet or worm-drive clamp over the barbed section to provide maximum security against pressure spikes.

Ideal For (Uses)

• Pump Plumbing: Creating a secure, removable connection point on the outlet of a submersible or centrifugal nutrient pump.
• Tank Take-offs: Connecting your main 19mm or 25mm supply line directly to the threaded bulkhead or tap of a reservoir.
• Valve Manifolds: Adapting standard 3/4" solenoid valves to interface with your poly pipe distribution network.
