The ASTURO MF 1/4" stainless steel fitting with pressure gauge is a professional accessory for pumps and spraying systems, designed to connect the material circuit and provide direct control of working pressure. It is suitable for coating systems, airless pumps, material feeding lines and technical applications where pressure must be monitored clearly during adjustment, start-up, continuous operation and maintenance. The analogue pressure gauge allows the operator to check the pressure value and adjust the pump with greater control.

The image shows a metal fitting with 1/4" male/female threaded connections, combined with an analogue pressure gauge with bar and psi scales. The dial allows pressure reading up to 400 bar / 6000 psi, a range consistent with high-pressure circuits typically used in airless applications and professional spraying systems. The compact configuration allows installation along the material line, near the pump or at a useful point in the circuit, depending on the system layout and the operator’s control requirements.

This accessory is particularly useful when working with paints, primers, undercoats, fillers, enamels, protective coatings, waterproofing products and technical materials that require stable pressure to obtain regular spraying. Pressure that is too low can cause an irregular spray fan, poor coverage, streaking or insufficient atomisation; pressure that is too high can increase overspray, material consumption, nozzle wear and stress on the circuit. The pressure gauge therefore allows the operator to monitor a key parameter for both application quality and operational safety.

During use, the fitting should be installed on components compatible with the MF 1/4" thread, always checking connection sealing and circuit suitability for the expected pressure. Before starting the system, the operator should make sure that the gauge is readable, undamaged and positioned so that it can be observed without exposure to dangerous areas. During spraying, the displayed value should be compared with product viscosity, nozzle diameter, required flow rate and the technical instructions of the pump or coating material used.

For technicians and maintenance operators, the fitting with pressure gauge is also useful for system diagnostics. Abnormal pressure variations may indicate clogged filters, worn or partially blocked nozzles, circuit leaks, irregular suction, insufficient material filtration or incorrect pump adjustment. Pressure reading therefore helps identify the causes of application defects more quickly and keeps the system operating under more stable working conditions.

In this product, precision is linked to pressure reading and control, not to dimensional measurement, height inspection, transmission play or geometric error analysis. The fitting with gauge improves repeatability in the spraying process because it helps the operator set and verify an essential operating parameter. Finish quality depends on the combination of pressure, viscosity, nozzle selection, spray distance, pass speed and substrate preparation.

The product is suitable for body shops, industrial maintenance, coating departments, workshops, construction sites, automotive companies, metal fabrication, machine tools, steel structures, panels, mechanical components and technical surfaces. To keep the accessory efficient over time, the circuit should be cleaned after use, residues inside the fitting should be avoided, pressure limits should not be exceeded and the condition of threads, seals and the pressure gauge dial should be checked periodically. The ASTURO MF 1/4" fitting with stainless steel pressure gauge is therefore a simple but essential component for better system control, improved application quality and professional use of spraying pumps.
