Malleable iron Pitcher tee reducing

  Datasheet (PDF)

The Georg Fischer pitcher tee 131 reducing on the branch is an engineered pipe fitting designed for branching fluid streams with minimal flow resistance and turbulence in industrial, municipal, and building services piping systems. Conforming to the ISO/EN E1 design standard, this specialized tee integrates a hydrodynamic curved sweep along the reducing branch line, promoting smooth laminar media transition and substantially lower localized pressure losses compared to conventional right-angle branch tees. Cast from decarburised annealed whiteheart malleable cast iron grade EN-GJMW-400-5 according to EN 1562, the component delivers exceptional mechanical tensile integrity, deformation resistance, and structural reliability under system vibration, thermal cycling, and pressure pulsations. The external and internal surfaces feature a durable hot-dip galvanized coating applied using high-purity zinc, providing comprehensive metallurgical barrier protection against oxidation, corrosion, and media wear, making it fully approved for potable water networks, heating water, non-aggressive gases, compressed air, and hydrocarbon transfer. Accurate internal parallel pipe threads conforming to EN 10226-1 and ISO 7-1 (Rp design) provide standard-compliant engagement with taper external threads (R) to generate robust, metal-to-metal contact and pressure-tight joints when combined with an appropriate sealing compound. Engineered to operate reliably across a broad temperature range from -20 degrees Celsius to 300 degrees Celsius with pressure ratings reaching 25 bar at standard temperatures, the fitting provides strict axial concentricity and exact laying dimensions compatible with standard prefabrication planning methods.
