Barbed fitting - female threaded with brass wing nut

Barbed fitting female threaded with brass wing nut Ezfitt (Reference: 503) represents excellence in connection solutions for irrigation systems. This precision technical component combines the robustness of brass with Ezfitt's ingenious design, guaranteeing lasting performance in all irrigation applications. Manufactured according to ISO 228-1 standards for "G" gas threading, this fitting ensures universal compatibility with all professional equipment on the market.

Applications and benefits

This barbed fitting is suited to a wide range of irrigation applications, both for domestic users and professionals. In the home setting, it enables reliable connections between garden hoses and spray guns, watering lances or micro-irrigation systems. Landscape, agricultural and horticultural professionals appreciate its ability to withstand the intensive demands of job sites.

The wing nut is a key asset of this product: it allows manual tightening and loosening without the need for specific tools. This feature proves particularly valuable during maintenance operations, network modifications or seasonal storage. The 2-piece design also facilitates cleaning operations and inspection of the elastomer seal condition.

Technical specifications and innovation

The choice of brass as the primary material gives this fitting exceptional resistance to corrosion and thermal variations. This characteristic guarantees a long service life, even in humid environments or those exposed to the elements. The barbed surface of the fitting ensures optimum grip with the hose, preventing any slippage even under pressure.

The integrated elastomer seal benefits from a specially developed formulation designed to resist UV, extreme temperatures and chemicals commonly used in gardening. This chemical resistance allows the use of nutrient solutions, liquid fertilisers or phytosanitary treatments without affecting the sealing properties.

The nominal pressure of 10 bar (PN 10) places this fitting in the category of professional equipment, capable of withstanding the high pressures of surface pumps and pressurised systems. This capacity allows its use in automated irrigation installations or extensive distribution networks.

Installation and use

Installing this barbed fitting requires careful preparation of the hose to ensure a perfect seal. Begin by making a clean, perpendicular cut of the hose using a cutter or hose cutter. Check for any burrs that could damage the elastomer seal during insertion.

For assembly, lightly moisten the inside of the hose with soapy water to facilitate insertion of the barbed fitting. Firmly push the fitting in up to the stop, ensuring that all the barbs are fully engaged within the thickness of the hose. Then position the hose clamp (sold separately) over the barbed section and progressively tighten to ensure mechanical fastening.

Maintenance of this fitting is limited to periodic visual inspection of the elastomer seal and occasional cleaning of the wing nut. At the end of the season, a complete disassembly allows inspection of all components and thorough cleaning before reassembly.

Expert advice and product synergies

The effectiveness of this barbed fitting is greatly enhanced when combined with professional-quality hose clamps. Favour stainless steel worm-drive clamps for optimum mechanical holding, particularly in installations subject to vibrations or frequent pressure variations.

For professional applications, consider integrating this fitting into a modular system including shut-off valves, pressure reducers and filters. This systemic approach ensures uniform and controlled water distribution, optimising irrigation efficiency while preserving the service life of all components.

A common mistake is to over-tighten the wing nut, risking damage to the elastomer seal or causing deformation of the thread. A firm manual tightening is generally sufficient to ensure a perfect seal. In the event of residual leakage, check the condition and positioning of the seal before increasing the tightening torque.

For seasonal installations, plan for disassembly and storage away from frost. Although brass resists sub-zero temperatures, the expansion of residual water could damage the elastomer seal or create mechanical stress in the assembly.
