BRASS AND PLASTIC FITTINGS FOR LANCES, KNAPSACK PUMPS, AND SPRAYING SYSTEMS

Fittings

Dal Degan spraying fittings are essential components for connecting pumps, hoses, lances, extensions, control units, and nozzles within a crop protection distribution system. Despite their small size, they play a fundamental role in ensuring circuit tightness, operator safety, and the reliability of the entire spraying system. Used on knapsack pumps, pressure sprayers, atomizers, sprayers, tank units, and weeding systems, these fittings allow for new installations, repairs, and the adaptation of components with different specifications without replacing the entire system. Dal Degan offers a complete range of agricultural fittings in brass and engineering plastic, designed to meet the needs of both professional gardening and specialized agriculture. Brass and plastic fittings Brass fittings are the ideal choice for professional and intensive use. They offer high mechanical resistance, excellent durability, and great reliability even with aggressive crop protection products. They are particularly suitable for farms, contractors, and users who frequently assemble and disassemble equipment. Engineering plastic fittings are a lightweight and economical solution, ideal for knapsack pumps, gardening systems, and hobby applications where pressures and stresses are lower. Main types of fittings The Dal Degan range includes all configurations commonly used in spraying systems. Hose barbs allow for the connection of flexible PVC or rubber hoses to the threaded components of the system and are available in various diameters and configurations. 90-degree elbows allow for changing the circuit direction without compromising liquid flow, making them particularly useful in tight spaces. Reducers allow for connecting components with different diameters or threads, facilitating the repair and upgrading of existing systems. Three-way fittings are used to create branches and feed multiple distribution lines from a single delivery point. The range also includes swivels, nuts, adapters, joints, ball valves, and numerous accessories for agricultural lances and pumps. Compatibility with pumps, lances, and atomizers All Dal Degan fittings use the most common standard threads in the agricultural spraying sector, including 1/2″ gas, 3/8″ gas, and peronospora thread. This feature ensures compatibility with Dal Degan manual and motorized knapsack pumps, pressure sprayers, atomizers, sprayers, tank units, lances, extensions, nozzles, and high-pressure hoses, as well as equipment from many other manufacturers. Thanks to the wide availability of configurations and spare parts, Dal Degan fittings are a reliable solution for the maintenance, repair, and customization of spraying systems for crop protection, weeding, professional gardening, and specialized agriculture.
