• Universal compatibility with NPT threads on both ends, ensuring leak-proof connections with iron and steel fittings
• Versatile fluid handling for air, natural gas, oil, steam, and water applications, reducing inventory needs
• Precision-engineered dimensions (4.026" ID, 4 1/2" OD) for consistent fit and optimal flow in 4" pipe systems
• Robust welded construction providing superior structural integrity under thermal and mechanical stress
• Standardized compliance with ASME B1.20.1, ASTM A53, and ASTM A733 for guaranteed interchangeability

Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical engineering solutions for industrial fluid systems. The welded construction and Schedule 40 wall thickness maintain structural stability under pressure fluctuations in air, natural gas, oil, steam, and water applications. NPT threading on both ends creates secure, standardized connections with iron and steel fittings, eliminating leakage risks in Class 125/150 systems. The protective black coating combats corrosion in harsh environments, while the precise 4" diameter and 6" length ensure seamless integration into existing standard-wall steel pipe networks, minimizing installation time and maintenance costs.
