Brass Hose Barb Fittings | 4mm to 19mm Connectors for Water & Air Lines

This brass barb pipe fitting is a versatile 2, 3, or 4-way connector designed for secure, leak-resistant junctions in pneumatic and low-pressure fluid systems. It accommodates a wide range of hose sizes from 4mm to 19mm, providing a durable and corrosion-resistant connection point for copper, nylon, or polyurethane tubing. Features and Benefits - Machined from solid brass - Provides excellent corrosion resistance and long-term durability for reliable performance in demanding environments. - Multi-port configurations (2, 3, 4-way) - Offers maximum flexibility for creating complex tubing networks, T-junctions, or simple extensions from a single fitting. - Compatible with 4mm to 19mm hose IDs - A single fitting type serves multiple hose sizes, reducing inventory needs and simplifying system design. - Barbed stem design with hose clamp grooves - Ensures a tight, secure grip on tubing to prevent blow-offs and maintain consistent system pressure. - Precision-machined threads - Allows for easy installation and a clean, professional finish when connecting to standard NPT or BSP threaded ports. Applications - Pneumatic control systems - Ideal for distributing air supply to multiple cylinders, valves, or tools in workshop and automation setups. - Aquaponics and hydroponics - Perfect for creating custom irrigation manifolds and water distribution networks with flexible tubing. - Low-pressure coolant lines - Suitable for routing coolant in CNC machines, 3D printers, or other equipment requiring reliable fluid transfer. - DIY and prototyping projects - An excellent choice for hobbyists and engineers building custom pneumatic or fluidic circuits for models or testing rigs.
