Flanges compliant with the SAE J518 standard are the international reference for connections in high-pressure hydraulic systems. Designed to withstand fatigue cycles, vibrations and pressure peaks, they provide superior leak-tight performance compared with traditional threaded fittings, while simplifying radial assembly and disassembly without generating torsional stress on the piping.
The range includes several configurations to suit different system layouts. For permanent connections, socket-weld flanges allow guided pipe insertion, while butt-weld flanges ensure maximum sealing performance with full-penetration welding. Where welding is not required, threaded flanges provide quick mechanical connection. Fastening to components such as pumps or valve blocks is effectively managed by half flanges, which ensure even distribution of the clamping preload across the bolts. The assembly is completed by pipe stubs, which are essential for housing the sealing O-ring. Finally, blind flanges and blind counter flanges are used during testing, flushing or for the safe isolation of hydraulic lines.
The use of these components is essential in heavy industry, earthmoving equipment and the marine sector to eliminate fluid leakage and significantly reduce plant downtime and maintenance costs.
