Brass Wing Nut Union Hose Fitting

Brass Wing Nut Union Hose Fitting Ezfitt (Reference: 504) - Professional connection solution for irrigation systems, this technical component ensures watertight and durable assemblies on all your hydraulic networks. Compliant with ISO 228-1 standards, this fitting combines the robustness of brass with ease of installation thanks to its wing nut.

Benefits and practical applications

This union hose fitting Ezfitt is designed for amateur and professional gardeners seeking reliable connections for their irrigation systems. Its barbed design ensures an optimal grip on the hose, while the wing nut enables easy hand-tightening and loosening without any specific tools. Perfect for connecting sections of garden hose, creating branch lines, or repairing a damaged section.

Landscape professionals appreciate its weather resistance and its ability to withstand a working pressure of 10 bar, sufficient for most domestic and semi-professional irrigation applications. Home users benefit from its ease of use and exceptional longevity.

Technical specifications and materials

Made from quality brass, this fitting is naturally resistant to corrosion and temperature variations. Brass also offers excellent mechanical properties, ensuring long-lasting performance even under repeated stress. The integrated elastomer seal ensures a perfect watertight assembly, compatible with cold and warm water.

The gas thread ''G'' ISO 228-1 complies with international standards, ensuring optimal compatibility with the majority of irrigation equipment on the market. The barbed design allows for a secure hose insertion, preventing any slippage under pressure. The nominal pressure PN 10 bar comfortably covers the needs of domestic and semi-professional installations.

Installation and practical use

Installing this union hose fitting is particularly straightforward. Start by sliding the wing nut onto the hose, then firmly push the hose onto the barbed part of the fitting until it reaches the stop. Then hand-tighten the wing nut, ensuring the elastomer seal is correctly positioned. Moderate tightening is sufficient to guarantee a watertight seal.

For optimal use, regularly check the condition of the elastomer seal, particularly after frost periods. When dismantling, gradually unscrew the wing nut to avoid damaging the threads. The fitting supports repeated connections/disconnections without loss of watertightness.

Maintenance is limited to occasional cleaning with soapy water and checking for the absence of limescale deposits on the threads.

Expert tips and product synergies

To maximise the durability of your installation, pair this union fitting with suitable hose clamps that permanently secure the hose insertion. This double security is particularly recommended for installations subject to significant pressure variations.

Professional tip: For temporary installations (seasonal watering), mark the optimal tightening position of the wing nut to facilitate subsequent reassembly. Avoid over-tightening, which could deform the elastomer seal and compromise long-term watertightness.

This fitting integrates perfectly into a system approach with other Ezfitt components: stop valves, branch fittings, elbow connectors. For professionals, keeping a stock of spare parts facilitates preventive maintenance of client installations.
