S-1443N188 1.049" ID x 1 5/16" OD x 6" Long ASME B1.20.1, ASTM A733 Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe with Sealant

Key Features & Benefits at a Glance

• Leak-proof performance with factory-applied PTFE thread sealant, eliminating the need for additional sealing compounds and ensuring reliable connections in demanding environments.
• Superior corrosion resistance due to 316/316L stainless steel construction, providing long-term durability in harsh chemical and moisture-rich applications.
• High-pressure compatibility with Class 150 fittings and flanges, making it suitable for air, natural gas, oil, steam, and water systems without failure.
• Precision threading per NPT standards (ASME B1.20.1) for secure, tight fits that minimize the risk of loosening under vibration or thermal cycling.
• Time-saving installation with threaded both ends design and welded construction, enabling quick assembly and reducing labor costs in industrial setups.
• Regulatory compliance with ASTM A733 and RoHS 3, ensuring environmental safety and meeting global industry standards for material quality.
• Versatile fluid handling across multiple media, thanks to its 1" Schedule 40 dimensions and robust wall thickness (0.133"), which support consistent flow and structural integrity.

Professional Applications & Engineering Value

This 316 stainless steel threaded pipe nipple is engineered to address common industrial challenges such as fluid leakage, corrosion-induced failures, and installation inefficiencies. The PTFE thread sealant integrated during manufacturing creates an immediate, reliable seal that withstands thermal expansion and pressure fluctuations in systems handling air, natural gas, oil, steam, or water. Its welded construction and NPT threading ensure a robust connection that resists vibration and mechanical stress, reducing maintenance downtime in plants, pipelines, and processing facilities. By using corrosion-resistant 316/316L stainless steel, it excels in aggressive environments like chemical processing or marine applications, offering long-term cost savings through extended service life and minimized replacement needs.
