  • Seamless construction eliminates weak points, providing superior structural integrity and leak prevention under high-pressure conditions.
  • Heavy-duty Schedule 80 wall thickness offers enhanced burst strength and durability for handling air, hydraulic fluids, oil, and steam safely.
  • Precision NPT threads on both ends guarantee a secure, leak-tight connection between 3/4" and 1/4" piping systems, minimizing installation time and fluid loss.
  • Full compliance with ASTM A403 and MSS SP-95 assures consistent quality, dimensional accuracy, and performance in industrial fluid and gas transfer applications.
  • REACH and RoHS 3 compliance meets stringent environmental and safety regulations, making it suitable for global industrial supply chains.
  • Versatile media compatibility allows use with water, natural gas, oil, and steam, streamlining inventory for multiple plant applications.

Professional Applications & Engineering Value

This Schedule 80 stainless steel pipe reducer is engineered to solve critical challenges in industrial piping systems where pressure integrity and corrosion resistance are paramount. Its seamless 304/304L stainless steel construction prevents failure at high pressures and aggressive media, such as hydraulic fluid and steam, while the NPT threaded design ensures a robust, leak-free interface between different pipe sizes. By reducing from 3/4" to 1/4" NPT, it optimizes flow control in compressed air lines, fuel transfer systems, and process water networks, minimizing pressure drops and installation complexity. The thick-wall profile and compliance with ASTM A403 provide engineers with a reliable, specification-grade component that extends service life and reduces downtime in harsh operating conditions.

Specification Summary & Compliance

This pipe reducer features precision NPT threads on both ends with standard dimensional tolerances, manufactured from seamless 304/304L stainless steel under ASTM A403 and MSS SP-95 specifications. It is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring adherence to environmental and health standards for industrial use.
