Professional Applications & Engineering Value

This 3/8" Schedule 80 stainless steel threaded pipe nipple delivers critical engineering value in demanding fluid and gas handling systems. The seamless 304/304L stainless steel construction eliminates weak points common in welded alternatives, providing exceptional resistance to high-pressure surges and corrosive media like hydraulic fluid, steam, and natural gas. With NPT threading on both ends, it ensures leak-free connections in industrial piping networks, while the thick-wall Schedule 80 design maintains integrity under cyclic loading. Engineers specify this pipe nipple for its ability to withstand thermal expansion and aggressive chemicals, reducing maintenance downtime in chemical processing, power generation, and oil & gas applications.

Specification Summary & Compliance

This product features precision NPT threading conforming to ASME B1.20.1 standards with Class 2A tolerance for reliable engagement. Manufacturing follows ASTM A733 specifications for seamless stainless steel pipe, ensuring dimensional accuracy with 6" length, 0.423" ID, and 43/64" OD. The Schedule 80 wall thickness (0.126") provides consistent pressure rating performance. Compliance includes RoHS 3 (2015/863/EU) for hazardous substance restriction, making it suitable for global industrial and environmental regulations.
