S-1443N176 0.824" ID x 1 3/64" OD x 5" Long ASME B1.20.1, ASTM A733 Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe with Sealant

Key Features & Benefits at a Glance

• Factory-applied PTFE thread sealant eliminates the need for additional sealing compounds, ensuring leak-free connections and reducing installation time in critical fluid and gas systems.
• Superior corrosion resistance from 316/316L stainless steel construction provides long-lasting durability in harsh environments, including exposure to chemicals, moisture, and extreme temperatures.
• Precision NPT threading on both ends guarantees a secure, tight fit with compatible fittings, minimizing the risk of thread stripping and connection failure under pressure.
• Robust welded construction and Schedule 40 wall thickness deliver high pressure tolerance and structural integrity for demanding applications with air, natural gas, oil, steam, and water.
• Compliance with ASME B1.20.1 and ASTM A733 standards ensures consistent dimensional accuracy, thread quality, and material properties for reliable performance in regulated industrial settings.
• RoHS 3 compliance confirms the fitting is free from hazardous substances, making it suitable for use in environmentally sensitive and regulated industries.
• Versatile male threaded design simplifies integration into existing piping systems, offering a straightforward solution for extensions, repairs, or new installations.

Professional Applications & Engineering Value

This 3/4 NPT stainless steel threaded pipe nipple is engineered to address common challenges in industrial fluid and gas handling, such as leakage, corrosion, and installation inefficiency. The 316/316L stainless steel material provides exceptional resistance to pitting and crevice corrosion, which is critical in applications involving steam, oil, and natural gas where moisture and aggressive media are present. The integrated PTFE thread sealant acts as a permanent lubricant and seal, preventing galling during assembly and ensuring a tight seal without relying on external tapes or pastes that can degrade over time. This is particularly valuable in high-vibration or thermal cycling environments, such as in process piping, compressor lines, and hydraulic systems, where maintaining seal integrity is essential for operational safety and minimizing downtime. The combination of welded construction and standard NPT threading makes it a reliable choice for extending pipe runs, connecting valves, or assembling custom configurations in HVAC, petrochemical, and water treatment facilities.

Specification Summary & Compliance

This pipe nipple features NPT (National Pipe Taper) threads conforming to ASME B1.20.1 for precise thread form and fit, ensuring compatibility with standard threaded fittings. The Schedule 40 wall thickness and dimensions (5" length, 0.824" ID, 1 3/64" OD) adhere to industry norms for pressure rating and flow characteristics. Manufactured in accordance with ASTM A733 for welded and seamless carbon and alloy steel pipe, it guarantees material consistency and mechanical properties. The product is RoHS 3 (2015/863/EU) Compliant, confirming it meets strict environmental regulations for hazardous substance restrictions, and is suitable for use in Class 150 applications with compatible flanges and fittings made from 316 or 316/316L stainless steel.
