Reducing cross malleable iron

  Datasheet (PDF)

The Georg Fischer reducing cross 180 galvanised malleable cast iron fitting provides a reliable, robust four-way junction engineered for branching, dividing, and distributing fluid streams across intersecting pipelines while seamlessly reducing diameter on the opposing branch outlets. Manufactured from high-grade decarburised annealed whiteheart malleable cast iron grade EN-GJMW-400-5 in full compliance with EN 10242 and ISO 49 Design Symbol A, the fitting exhibits superior cast integrity, high shock resistance, and durable structural tenacity. Internal parallel jointing threads Rp conforming to EN 10226-1 and ISO 7-1 are precision-cut across all four outlets to engage flawlessly with taper external threads R, generating intimate metallic flank contact that achieves reliable, permanent pressure tightness when coupled with thread sealants such as hemp, PTFE cord, or anaerobic sealing compounds. The entire component is protected with a uniform hot-dip galvanised zinc finish derived from high-purity raw zinc, providing exceptional barrier protection against corrosion, rust formation, and harsh industrial atmospheres while meeting stringent hygienic standards for potable water conveying. Engineered for rigorous mechanical demands across liquid and gas pipeline infrastructure, heating and cooling loops, compressed air systems, and industrial plant processing, the fitting accommodates continuous operating temperatures from -20 degrees Celsius to 120 degrees Celsius at a maximum permissible working pressure of 25 bar, maintaining a pressure rating of 20 bar at elevated temperatures up to 300 degrees Celsius. Standardised laying dimensions and calibrated z-measurements across run and reduced branch sizes spanning 3/4 inch to 2 inches streamline accurate pipe cut lengths, allowing efficient axial alignment, simplified layout verification, and distortion-free prefabrication of complex threaded piping networks.
