Professional Applications & Engineering Value

This black-coated steel pipe nipple delivers exceptional engineering value in industrial fluid transfer systems. The welded construction combined with NPT threaded ends creates a robust connection solution that prevents leakage in high-vibration environments. Engineered to handle multiple media including compressed air, natural gas, oil, steam, and water, this component eliminates the need for multiple fitting types in mixed-system applications. The Schedule 40 wall thickness (0.091") provides optimal pressure containment while maintaining flow efficiency. Particularly valuable in petrochemical, manufacturing, and utility applications where iron and steel flange compatibility is essential, this nipple ensures reliable performance across temperature variations and mechanical stress conditions.

Specification Summary & Compliance

Manufactured to exacting standards with NPT thread specifications per ASME B1.20.1, ensuring proper engagement and sealing performance. The 3/8" pipe size with 1-1/2" length maintains dimensional accuracy for seamless integration into existing systems. Complies with ASTM A53 for material quality and ASTM A733 for welded and seamless carbon steel tubing requirements. The black-coated surface treatment provides additional corrosion protection while maintaining Class 2A thread tolerances for reliable mating with female threaded components. Suitable for use with iron and steel fittings rated for Classes 125 and 150 pressure applications.
