Applications:
These versatile 13-4mm reducing fittings are ideal for a wide range of applications including:

• Hydroponics systems - create efficient water distribution networks
• Hanging basket irrigation - deliver precise water flow to multiple baskets
• Pots and raised beds - establish targeted watering systems
• Aquarium setups - construct reliable water circulation systems
• Water butt connections - develop gravity-fed irrigation networks

Brand: The 13-4mm Tee is Antelco brand. The other parts are unbranded.

Specification:
• Material: Polypropylene
• Large end: 13mm (1/2") internal diameter
• Small end: 4mm internal diameter
• Connection type: Barbed
• Pressure rating: Suitable for low-pressure systems
• Installation: Designed for flexible pipes that stretch over the barbs for a secure fit

Installation Tips:
For best results, use flexible tubing that can stretch slightly over the barbed ends. To ensure a secure connection, briefly immerse tubing ends in warm water to soften before fitting over the barbs. The double barb design provides additional grip for a leak-free seal without requiring clamps in most low-pressure applications. For outdoor installations, periodic inspection is recommended to ensure connections remain secure.
