Brass Hydraulic Fittings are generally crafted from high-quality brass alloys that include copper and zinc, adhering to standards like IS-319 or BS-218. This alloy offers moderate tensile strength, excellent ductility, and outstanding corrosion resistance in non-aggressive environments. The fittings come with precision threads, smooth sealing surfaces, and reliable metal-to-metal compression characteristics. Their mechanical properties include good tolerance to vibrations, consistent sealing under moderate pressure, and dependable performance within normal temperature ranges. Brass ensures long-lasting durability in clean fluid systems where extreme pressure or corrosive substances are absent.
