MS Union Fitting 25x20 mm

Mild Steel Union for Industrial Pipe Connections

This 25x20 mm MS union fitting provides a practical solution for connecting pipes with a 25 mm and 20 mm nominal bore. The mild steel construction offers good strength and durability, making it suitable for non-corrosive fluid and air transfer in workshop and industrial environments. The three-piece design—consisting of a nut and two female-threaded ends—enables quick disconnection without rotating the pipes, which is a key advantage during equipment maintenance or hose replacement on blasting machines.

Applications in Abrasive Blasting and Surface Preparation

In abrasive blasting setups, pipe fittings must withstand vibration, frequent assembly changes, and the passage of compressed air. This MS union is typically installed in air supply lines, abrasive metering systems, or dust collector ducting where a reliable, serviceable joint is required. Its reducing size (25x20 mm) helps transition between different pipe diameters, a common requirement when connecting a blast machine outlet to a smaller nozzle holder or coupling.

Selection and Compatibility Considerations

To ensure a proper fit, confirm the thread standard (BSP or NPT) and the exact inner and outer diameters of your existing pipes. While MS unions are cost-effective, they are best suited for dry, non-corrosive environments. For wet blasting or chemical exposure, a stainless steel alternative may be required. Always match the pressure rating of the union to your system's maximum operating pressure to prevent failures.
