• Schedule 40 wall thickness (0.109") offers optimal strength-to-weight ratio for handling moderate pressures without unnecessary bulk.
• Full ASTM B241 compliance guarantees material quality and dimensional accuracy for consistent performance across installations.
• RoHS 3 compliance meets international environmental standards, making it suitable for regulated industries and global supply chains.
• 6 1/2" straight length provides versatile spacing flexibility while maintaining structural rigidity in piping layouts.

Professional Applications & Engineering Value

This heavy-duty aluminum threaded pipe nipple solves critical challenges in industrial fluid and pneumatic systems where corrosion resistance and weight reduction are paramount. The seamless 6061 aluminum construction prevents failure points common in welded alternatives, while the NPT male threads ensure leak-free connections in compressed air lines, hydraulic oil circuits, and water cooling systems. Engineers specify this ASTM B241 compliant fitting for applications requiring Class 150 pressure rating compatibility with aluminum flanges and fittings, particularly in manufacturing plants, processing facilities, and mobile equipment where aluminum's non-sparking properties enhance safety. The Schedule 40 dimensions provide standardized interoperability with existing piping infrastructure while the RoHS 3 compliance addresses environmental regulations without compromising performance.

Specification Summary & Compliance

This 1/2" NPT aluminum threaded pipe nipple maintains precise NPT thread standards with 0.622" ID and 27/32" OD dimensions per Schedule 40 requirements. Manufacturing follows ASTM B241 specifications for aluminum alloy pipe, ensuring consistent material properties and dimensional tolerances. The product is fully RoHS 3 (2015/863/EU) compliant and suitable for use with Class 150 aluminum fittings and Class 125 aluminum flanges in air, oil, and water service applications.
