Safe for potable water and sensitive applications with NSF/ANSI 61 certification, ensuring compliance with drinking water standards and environmental safety.
Broad industry compliance including ASTM B687, Fed. Spec. WW-N-351C, and RoHS 3, guaranteeing material quality and regulatory adherence for global projects.
Durable and leak-resistant design with precise threading and seamless build, ideal for repetitive use in industrial plumbing, HVAC, and process piping.

Professional Applications & Engineering Value

This 2" Schedule 40 brass threaded pipe nipple is engineered to address common industrial challenges such as corrosion, high-pressure stress, and fluid compatibility. The seamless 230 brass construction provides inherent resistance to rust and degradation, making it ideal for air, drinking water, natural gas, oil, and steam systems. Its NPT male threads on both ends ensure a tight, reliable seal that withstands vibration and thermal cycling, reducing downtime in industrial plumbing, HVAC, and process piping. By meeting ASTM B687 and NSF/ANSI 61 standards, it offers peace of mind for applications requiring strict hygiene and safety, from water treatment plants to energy distribution networks.

Specification Summary & Compliance

This product adheres to precise dimensional standards with NPT thread type for consistent fit and Schedule 40 wall thickness (0.154") for robust pressure handling. It conforms to ASTM B687 for material integrity, Fed. Spec. WW-N-351C for federal applications, and NSF/ANSI 61 for drinking water safety. Additionally, it is RoHS 3 (2015/863/EU) Compliant, ensuring environmental responsibility and global regulatory acceptance.
