S-5038K434 1.38" ID x 1 21/32" OD x 20" Long ASTM B241 Standard-Wall Aluminum Threaded Pipe Nipples and Pipe

Key Features & Benefits at a Glance

• Superior corrosion resistance from 6061 aluminum construction ensures long-term reliability in harsh industrial environments with air, oil, and water systems.
• Leak-resistant NPT threading on both ends provides secure, tight connections that maintain system integrity under pressure.
• Seamless construction eliminates weak points, enhancing burst pressure resistance and preventing failure in demanding applications.
• Precise Schedule 40 dimensions (1.38" ID, 1 21/32" OD) guarantee compatibility with standard piping systems, reducing installation time and errors.
• ASTM B241 compliance certifies consistent material quality and mechanical properties for engineering-critical installations.
• RoHS 3 environmental compliance meets modern regulatory requirements while maintaining full performance capabilities.
• 20-inch male-threaded design enables flexible spacing configurations while withstanding Class 125/150 flange pressures.

Professional Applications & Engineering Value

This 6061 aluminum threaded pipe nipple solves critical industrial challenges where corrosion, pressure integrity, and regulatory compliance intersect. The seamless aluminum construction combined with NPT threading creates a robust solution for compressed air systems that demand moisture resistance, hydraulic oil lines requiring vibration tolerance, and water processing applications needing non-contaminating surfaces. Engineers specify this Schedule 40 pipe nipple for its predictable performance across temperature variations and mechanical stresses, while maintenance teams appreciate the standardized dimensions that simplify replacements in aluminum piping systems. The 20-inch length provides optimal spacing flexibility between components without requiring custom fabrication.
