• ASTM B241 compliance guarantees consistent material quality and dimensional accuracy for industrial-grade performance.
• RoHS 3 compliance ensures environmental safety and meets global regulatory standards for hazardous substance restrictions.
• Heavy-duty Schedule 40 wall thickness (0.145") offers excellent pressure handling and durability in demanding applications.
• Versatile compatibility with air, oil, and water systems reduces inventory needs by serving multiple fluid handling requirements.

Professional Applications & Engineering Value

This 1 1/2" Schedule 40 aluminum threaded pipe nipple solves critical industrial challenges by combining 6061 aluminum's lightweight strength with seamless construction to prevent failure points in compressed air lines, hydraulic oil circuits, and water distribution systems. Its NPT male threading ensures leak-tight seals that withstand vibration and thermal cycling, while the 7-inch length provides flexible installation spacing. Engineers value its ASTM B241 certification for predictable performance in Class 150 aluminum fittings, eliminating galvanic corrosion risks when paired with aluminum flanges. The RoHS 3 compliance further supports sustainable manufacturing initiatives without compromising the corrosion resistance needed for long service life.

Specification Summary & Compliance

This nipple maintains precise NPT thread standards with a 1.61" ID and 1 29/32" OD per Schedule 40 dimensions. Manufacturing follows ASTM B241 specifications for aluminum alloy pipes, ensuring consistent wall thickness (0.145") and straightness. Complies with RoHS 3 (2015/863/EU) for hazardous substance restrictions and is rated for use with Class 125 aluminum flanges and Class 150 aluminum fittings in air, oil, and water service.
