This malleable iron service Tee A197 NPT is manufactured in full compliance with ASTM standards. It has equal main run sizes, and the branch is engineered for quick tapping, valve/meter installation—eliminating the need for extensive pipe cutting and system shutdowns, thus significantly improving piping modification and maintenance efficiency. Constructed from black heart malleable iron with high-temperature graphitization annealing, it delivers exceptional toughness, impact resistance and low-temperature performance. Precision threads meet ANSI B1.20.1 (NPT) specifications, with smooth sealing surfaces free of burrs or scratches for leak-proof connections. Available in black, electro-galvanized and hot-dip galvanized finishes, it is ideal for water supply, gas, fire protection, HVAC and low-pressure industrial fluid systems, serving as a critical fitting for building, municipal and plant piping retrofits, new branch additions and instrument mounting.
Malleable cast iron service tee has two ends with female threads and the other end without male threads, used to connect pipes. Used to change the direction of the fluid, used in the branch pipe of the main pipeline.
