Malleable cast iron union elbow (Taper seat / flat seat) is a detachable pipe fitting that provides a 90-degree directional change with leak-proof connections for a wide range of piping systems. Constructed from high-quality malleable iron, it consists of three components: a tail part, a head part, and a union nut, with female threads on both ends for installation. Ideal for plumbing, gas, water, and industrial pipelines, this union ensures easy installation, allows for quick disassembly during maintenance, and provides exceptional durability and long-term strength.
