Professional Applications & Engineering Value

This galvanized steel threaded pipe nipple is engineered to solve common industrial piping challenges, such as corrosion and joint failure. The galvanized coating provides a robust barrier against rust and chemical degradation, extending service life in systems handling air, natural gas, oil, steam, and water. Its NPT thread type on both ends ensures a tight, reliable seal with galvanized iron or steel fittings, minimizing leaks in high-vibration or pressure-varying environments. The welded construction and Schedule 40 wall thickness offer structural integrity, preventing burst or collapse under operational stress. Ideal for maintenance, repair, and new installations, this standard-wall pipe nipple delivers consistent performance, reducing downtime and replacement costs in industrial fluid transport applications.

Specification Summary & Compliance

This product features a 3/8" Pipe Size and Schedule 40 wall thickness (0.091"), with a 4" Length and Threaded Both Ends connection style. It conforms to NPT (National Pipe Taper) thread standards per ASME B1.20.1, ensuring proper fit and sealing. Manufacturing and material quality are verified through compliance with ASTM A53 (specifying steel pipe properties) and ASTM A733 (covering welded and seamless carbon steel tubing). The nipple is designed for use with Class 125 and 150 fittings, confirming its suitability for standard industrial pressure ratings.
