S-4778K199 2.086" ID x 2 3/8" OD x 1 59/64" Long ANSI/ASME BS21, ASME B1.20.1, DIN EN 10226 Standard-Wall Steel Threaded Pipe Nipples and Pipe

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-coated steel construction, extending service life in demanding industrial environments
• Universal compatibility with BSPT × NPT dual-thread design for seamless connections across international piping systems
• Enhanced pressure integrity through welded construction, maintaining reliability with air, natural gas, oil, steam, and water up to Class 150
• Full-thread engagement ensures secure, leak-free installations and superior vibration resistance in high-flow applications
• Precision dimensional compliance with Schedule 40 specifications guarantees consistent fit and optimal flow characteristics
• Regulatory confidence with REACH and RoHS 3 compliance, meeting stringent international environmental and safety standards
• Robust material pairing with iron and steel flanges prevents galvanic corrosion and maintains system integrity

Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple solves critical connectivity challenges in industrial fluid systems where pressure integrity and material compatibility are paramount. The welded construction and fully threaded BSPT × NPT design eliminate common failure points in air, natural gas, oil, steam, and water applications, providing engineers with a unified solution for transitioning between British and American piping standards. Its Schedule 40 wall thickness (0.145") maintains optimal ID/OD ratios while withstanding cyclic pressure stresses, making it ideal for Class 150 iron/steel flange systems in chemical processing, power generation, and industrial plumbing where leak prevention and long-term durability are non-negotiable requirements.
