Heavy-duty Schedule 80 wall thickness provides exceptional strength and durability for demanding industrial fluid handling.
Versatile media compatibility safely handles air, nitrogen gas, oil, steam, and water, simplifying inventory for multiple applications.
Seamless transition between 4" and 2 1/2" piping optimizes flow efficiency and space in complex pipe systems.
Compliance with major industry standards ensures consistent quality, safety, and interoperability in professional installations.

Professional Applications & Engineering Value

This galvanized iron reducer nipple is engineered to address common industrial challenges such as corrosion, pressure drops, and connection integrity. The seamless construction and galvanized surface provide a robust barrier against rust and degradation, making it ideal for harsh environments involving steam, oil, or water. With NPT threaded both ends, it ensures a tight seal that withstands vibration and thermal cycling, reducing the risk of leaks in air, nitrogen gas, or high-temperature fluid systems. Its Schedule 80 design offers enhanced wall thickness for added safety in high-pressure applications, while the precise 4" to 2 1/2" reduction facilitates efficient flow control in industrial piping networks, minimizing energy loss and maintenance downtime.

Specification Summary & Compliance

This reducer nipple features NPT thread type conforming to ASME B1.20.1 for precise fit and leak-resistant connections. It meets material standards including ASTM A234 and ASTM B633, with construction adhering to MSS SP-95. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental safety and regulatory adherence for global industrial use.
