S-1443N161 0.622" ID x 27/32" OD x 3" Long ASME B1.20.1, ASTM A733 Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe with Sealant

Key Features & Benefits at a Glance

• Pre-applied PTFE thread sealant ensures immediate, leak-proof connections without additional sealing compounds, saving installation time and reducing maintenance risks.
• 316/316L stainless steel construction delivers superior corrosion resistance in harsh environments, extending service life with air, natural gas, oil, steam, and water systems.
• Welded design and NPT threading on both ends provide robust, vibration-resistant joints that maintain integrity under high-pressure conditions (Class 150).
• Schedule 40 standard-wall thickness offers optimal strength-to-weight ratio for durable performance in industrial piping networks.
• Compliance with ASME B1.20.1 and ASTM A733 guarantees precise thread dimensions and material quality, ensuring reliable interchangeability and safety.
• RoHS 3 compliance meets environmental regulations for hazardous substance restrictions, supporting sustainable procurement practices.
• 3" length with male threaded connections enables flexible installation in tight spaces while maintaining full flow capacity (0.622" ID).

Professional Applications & Engineering Value

Engineered for demanding fluid and gas handling systems, this 316 stainless steel threaded pipe nipple integrates PTFE thread sealant to eliminate common leakage issues in compressed air, natural gas, oil transfer, steam lines, and water pipelines. The welded construction and NPT threads create a secure, pressure-tight seal that withstands thermal cycling and chemical exposure. By combining corrosion-resistant 316/316L material with factory-applied sealing, it reduces downtime in maintenance-intensive environments like chemical plants, HVAC systems, and industrial processing units. Its Schedule 40 profile and standardized dimensions ensure compatibility with existing 150 Class fittings, streamlining retrofits and new installations while adhering to ASME and ASTM specifications for consistent performance.
