Professional Applications & Engineering Value

This 3/8 NPT threaded pipe nipple delivers critical performance where corrosion resistance and pressure integrity matter most. The seamless 316/316L stainless steel construction eliminates weld weaknesses that commonly fail in chemical processing, marine applications, and oil & gas systems. With NPT threading conforming to ASME B1.20.1, engineers achieve reliable, leak-free connections in steam lines, compressed air systems, and hydraulic applications. The Schedule 40 wall thickness provides exceptional burst strength while the 14-inch length offers flexibility in piping layouts. This combination of material excellence and precision manufacturing solves common failure points in industrial fluid handling systems.

Specification Summary & Compliance

This 3/8" NPT threaded pipe nipple features precision Class 2A threads per ASME B1.20.1 with 14-inch length and Schedule 40 dimensions (0.493" ID, 43/64" OD, 0.091" wall thickness). Manufactured to ASTM A733 specifications for seamless stainless steel pipe, the component is RoHS 3 (2015/863/EU) compliant and suitable for 150-class fittings and flanges in various industrial applications.
