The ASTURO stainless steel needle-air cap-nozzle set for G70/SSP is a technical spare parts kit designed to restore, maintain or adapt the spray assembly of the compatible spray gun item 00125. The set includes needle, nozzle, air cap and gasket, the components that determine coating material flow, material output, spray fan formation and atomisation quality. It is an essential spare part for keeping spray gun performance consistent and obtaining a regular finish on technical, metal, plastic, wood or bodywork surfaces.

The table shows several configurations available according to nozzle diameter: 1.2 mm, 1.4 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.5 mm and 3.0 mm. This range allows the operator to select the most suitable set according to the product applied, viscosity, required flow rate and desired finish. Smaller diameters are suitable for thinner materials, controlled finishes and applications requiring greater delivery precision, while larger diameters are suited to denser products, primers, fillers, heavy enamels or applications requiring higher material output.

The needle works together with the nozzle and controls the opening of the material passage. The nozzle determines the outlet diameter and therefore directly affects flow rate and material behaviour. The air cap contributes to air distribution and spray fan formation, while the gasket helps maintain correct sealing of the assembly. Correct matching of these components is essential to avoid irregular spraying, unstable atomisation, asymmetrical spray pattern, product leakage or adjustment difficulties.

The needle-air cap-nozzle set is useful both as a maintenance spare part and as a spray gun configuration element. With use, the needle and nozzle may wear, become marked, deform or become clogged by paint residues. The air cap may also lose efficiency if its holes become blocked or if the part is damaged by impact. In these cases, replacing the complete set helps restore more stable spraying, smoother trigger response and better finish quality.

For this product, precision is not related to dimensional measurement or metrological resolution, but to precise coating application. A properly centred and matched needle-nozzle assembly allows material to be dosed more predictably, flow to remain consistent and the spray fan to be controlled more effectively. Heights, transmission play and geometric errors are not measured by the kit, but the geometry and alignment of the internal components directly influence spray quality and result repeatability.

The field of use includes body shops, workshops, finishing departments, the wood industry, industrial maintenance, coating of metal components, plastic parts, panels, structures and technical surfaces. The possibility of choosing the nozzle diameter allows the painter to adapt the spray gun to primers, fillers, enamels, clear coats, water-based paints, colours and materials with different viscosities. Correct selection reduces rework, material waste, cosmetic defects and adjustment time.

Before installation, the spray gun should be cleaned thoroughly, compatibility with the G70/SSP model should be checked and the seats should be inspected to ensure they are free from dried residues or deposits. The components should be installed without forcing, avoiding excessive tightening that could damage the nozzle or needle. After replacement, a test on a sample panel is recommended, adjusting air and material until uniform atomisation and a spray fan consistent with the intended application are obtained.

To maintain spray quality over time, the needle, nozzle and air cap should be cleaned after every use with products compatible with the coating material applied. Hardened residues, blocked air cap holes or deposits inside the nozzle can alter flow rate, generate intermittent spraying and compromise the finish. The ASTURO stainless steel needle-air cap-nozzle set for G70/SSP is therefore an essential spare part for users who want to keep their spray gun efficient and achieve professional, regular and repeatable applications.
