Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers critical performance where corrosion resistance and pressure integrity are paramount. The welded construction combined with NPT threading creates a durable connection point that maintains seal integrity under thermal cycling and mechanical stress. Engineered for industrial fluid handling systems, it effectively manages air, natural gas, oil, steam, and water transfer while preventing galvanic corrosion when connecting to iron or steel fittings. The 24-inch length provides necessary reach in complex piping layouts, while the Schedule 40 wall thickness ensures reliable performance in medium-pressure applications common in manufacturing, processing, and utility systems.
Specification Summary & Compliance
This 3/8" NPT threaded pipe nipple features precision Class 2A thread tolerances per ASME B1.20.1 standard, ensuring proper engagement with mating components. Manufactured from ASTM A53 steel with ASTM A733 compliance for welded construction quality. The product maintains dimensional accuracy with 0.493" ID and 43/64" OD for consistent flow characteristics. Fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, meeting current environmental and substance restriction requirements for industrial applications.
