The ASME B16.9 Stainless Steel Reducing Cross is a four-way branch fitting designed to connect pipes of different diameters at a single intersection. Forged from high-grade stainless steel (304L/316L), it allows for a main header to feed smaller branch lines while maintaining 90° symmetry. The STD wall thickness ensures high pressure integrity for chemical and pharmaceutical manifolds. Its butt-weld design provides a permanent, leak-proof joint, making it superior to threaded fittings in high-vibration and corrosive services.
