Barbed Fittings: Female End with Union Nut

Barbed Female End Fitting with Union Nut Ezfitt (Reference: 517) represents the ideal technical solution for your professional irrigation connections. This high-quality 2-piece brass fitting guarantees a perfect seal and simplified installation for all your irrigation projects.

Applications and fields of use

This Ezfitt barbed female end fitting is perfectly suited to domestic and professional irrigation systems. Specially designed for home gardeners, landscapers and farmers, it allows you to efficiently connect your garden hoses to taps, valves or other fixed equipment.

Its barbed design ensures a secure grip on all types of flexible hoses, whether standard garden hoses, micro-porous hoses or drip irrigation lines. The union nut greatly facilitates assembly and allows precise adjustments without rotating the hose.

Gardening professionals particularly appreciate this fitting for temporary or semi-permanent installations, where ease of disassembly is essential. Compatible with the ISO 228-1 standard, it integrates seamlessly into existing networks.

Technical specifications and materials

Made from high-quality brass, this Ezfitt fitting benefits from exceptional resistance to corrosion and temperature variations. Brass, an alloy of copper and zinc, guarantees optimum longevity even in difficult outdoor conditions.

Its 2-piece design with union nut offers remarkable installation versatility. The barbed end slides into the hose while the union nut allows progressive and controlled tightening onto the destination thread. This design avoids torsional stress on the hose during assembly.

Rated PN 10 bar, this fitting withstands high service pressures, making it compatible with high-pressure irrigation systems and powerful surface pumps. The ISO 228-1 thread (''G'' gas thread) ensures universal compatibility with the majority of irrigation equipment on the market.

Installation and implementation

Installing this Ezfitt female end fitting requires minimal tooling and can be carried out by any user. Start by cleanly cutting the end of the hose with a sharp cutter to obtain a clean, perpendicular cut.

Thread the union nut onto the hose before inserting the barbed end. Push the end firmly until the barbs bite into the wall of the hose. This step is crucial to ensure the seal and mechanical hold of the assembly.

For the final connection, screw the union nut onto the destination thread while respecting the recommended tightening torque. Hand-tightening followed by a quarter turn with a spanner is generally sufficient. Avoid over-tightening, which could damage the thread or deform the sealing gasket.

Maintenance is limited to periodic checks of the seal and cleaning the threads if necessary. When disassembling, proceed carefully to preserve the integrity of the hose.

Expert tips and optimisations

To maximise the performance of this Ezfitt fitting, we recommend using additional hose clamps on critical installations or those subject to large pressure variations. These clamps, available in our accessories range, reinforce the mechanical hold of the assembly.

Experienced professionals often pair these female ends with male quick-connect fittings to create quickly disconnectable connections. This combination proves particularly useful for seasonal irrigation systems or temporary installations on landscaping sites.

Be mindful of thermal shock: although brass withstands temperature variations well, avoid sudden transitions from cold to hot which could create stress in the assembly. During freezing periods, systematically drain your installations to avoid breakage.

For intensive professional applications, regularly check the condition of the barbs and replace the fitting if you notice significant wear. A worn fitting can cause leaks and compromise the efficiency of your irrigation system.
