Professional Applications & Engineering Value

This 1 1/4" Schedule 40 aluminum threaded pipe nipple solves critical challenges in industrial fluid handling systems where corrosion resistance and reliability are paramount. The seamless 6061 aluminum construction prevents internal weak spots that commonly fail in welded alternatives, while the NPT male threading on both ends creates secure, pressure-tight connections without requiring additional adapters. Engineered for air, oil, and water applications, this nipple withstands chemical exposure and environmental factors that degrade inferior materials. The ASTM B241 compliance guarantees dimensional accuracy and material properties that maintenance engineers depend on for predictable performance in Class 150 and 125 flange systems, reducing downtime and replacement costs in processing plants, manufacturing facilities, and industrial utilities.

Specification Summary & Compliance

This aluminum threaded pipe nipple features precision NPT thread form with standard industrial tolerances, 1 1/4" Schedule 40 dimensions (1.38" ID, 1 21/32" OD), and 10" length. Manufactured to ASTM B241 specifications for aluminum pipe, it meets pressure rating requirements for Class 150 fittings and Class 125 flanges. The product is fully RoHS 3 (2015/863/EU) compliant, containing no restricted hazardous substances, making it suitable for global industrial applications with environmental regulations.
