• Seamless design enhances structural integrity and prevents weak points for reliable pressure handling
• Broad compatibility with air, natural gas, oil, and water systems, reducing inventory needs for multiple media types
• Precision threading with NPT standards ensures easy installation and secure connections in Class 125 brass fittings and Class 150 flanges
• Regulatory compliance with ASTM B687 and RoHS 3, providing assurance for industrial safety and environmental standards
• Durable Schedule 40 wall thickness of 0.145" offers excellent strength for high-pressure and repetitive use scenarios

Professional Applications & Engineering Value

This 1 1/2" NPT male threaded brass pipe nipple is engineered to address common industrial challenges such as fluid leakage, corrosion, and installation inefficiencies. The seamless 230 brass construction combined with a factory-applied acrylic thread sealant creates a robust, pre-sealed solution that withstands exposure to air, natural gas, oil, and water without degradation. Its NPT threading on both ends ensures quick, secure assembly in systems requiring Class 125 brass fittings or Class 150 flanges, minimizing downtime and maintenance. Ideal for HVAC, plumbing, and industrial processing, this nipple delivers consistent performance in high-vibration and temperature-variable environments, reducing the risk of system failures and enhancing operational reliability.

Specification Summary & Compliance

This product adheres to NPT thread standards with precise dimensions: 1 1/2" pipe size, Schedule 40, 4" length, 1.61" ID, and 1 29/32" OD. It meets ASTM B687 specifications for brass pipe manufacturing and is RoHS 3 (2015/863/EU) compliant, ensuring environmental safety and material consistency. The seamless build and threaded both-ends design support reliable integration in industrial applications requiring strict dimensional and performance tolerances.
