S-44665K218 0.824" ID x 1 3/64" OD x 5 1/2" Long ASTM B241 Standard-Wall Aluminum Threaded Pipe Nipples and Pipe

Key Features & Benefits at a Glance

• Seamless 6061 aluminum construction ensures superior leak resistance and long-term reliability in demanding air, oil, and water systems.
• NPT threads on both ends provide secure, standardized connections with aluminum fittings and flanges, reducing installation time and risk of cross-threading.
• ASTM B241 compliance guarantees material integrity and consistent performance under pressures up to Class 150 for fittings and Class 125 for flanges.
• Schedule 40 wall thickness (0.113") offers excellent durability and pressure handling for industrial piping without adding excessive weight.
• RoHS 3 compliance ensures environmental safety and regulatory adherence for global supply chains and sensitive applications.
• Straight, 5 1/2" length design allows for versatile spacing and alignment in compact or extended piping layouts.
• Lightweight aluminum material reduces system load and corrosion risks compared to steel, lowering maintenance costs over time.

Professional Applications & Engineering Value

This 3/4" NPT aluminum threaded pipe nipple is engineered to address common industrial challenges such as corrosion in air, oil, and water systems. Made from seamless 6061 aluminum, it prevents weak points and leaks that often occur in welded alternatives. The NPT threading on both ends ensures a tight seal with aluminum fittings (Class 150) and flanges (Class 125), making it ideal for HVAC, hydraulic, and plumbing setups where weight and durability are critical. Its Schedule 40 profile balances strength with flow efficiency, while RoHS 3 compliance supports use in regulated environments. This standard-wall aluminum pipe solution minimizes installation errors and extends service life in high-vibration or temperature-varying applications.
