Professional Applications & Engineering Value

This 3" Schedule 40 aluminum threaded pipe nipple delivers exceptional engineering value through its 6061 aluminum material grade and NPT threaded both ends design. The seamless construction eliminates weak points that commonly fail under pressure cycling, while the corrosion-resistant properties prevent degradation in harsh industrial environments handling air, oil, and water. Engineers specify this ASTM B241 compliant fitting for its reliable performance in Class 150 aluminum systems, where consistent thread engagement and pressure integrity are critical. The 4 1/2" length provides optimal spacing flexibility in complex piping layouts, making it ideal for industrial plants, manufacturing facilities, and processing systems requiring durable aluminum threaded connections.

Specification Summary & Compliance

This aluminum threaded pipe nipple features precise NPT thread specifications with standard pipe threading tolerances, 3" Schedule 40 dimensions (3.068" ID, 3 1/2" OD, 0.216" wall thickness), and 4 1/2" length. Manufactured to ASTM B241 standards for aluminum pipe, it ensures dimensional accuracy and material consistency. The product is fully RoHS 3 (2015/863/EU) compliant and suitable for use with aluminum fittings Class 150 and aluminum flanges Class 125, meeting industry requirements for environmental safety and material performance.
