S-1443N205 1.61" ID x 1 29/32" OD x 2 1/2" 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 installation with factory-applied PTFE thread sealant, eliminating the need for additional sealing compounds and reducing assembly time.
• Superior corrosion resistance from 316/316L stainless steel construction, ensuring long-term reliability in harsh chemical and moisture-rich environments.
• High-pressure compatibility with Schedule 40 wall thickness, providing robust performance for air, natural gas, oil, steam, and water systems up to Class 150.
• Precision NPT threading on both ends for secure, standardized connections that meet ASME B1.20.1 specifications, minimizing the risk of cross-threading.
• Durable welded construction enhances structural integrity, offering consistent performance under vibration and thermal cycling in industrial settings.
• RoHS 3 compliance ensures environmental safety and material quality, supporting sustainable procurement practices.
• Versatile fluid handling across multiple media including steam and natural gas, reducing inventory needs with a single, multi-application solution.

Professional Applications & Engineering Value

Engineered for demanding industrial systems, this 316/316L stainless steel threaded pipe nipple integrates a PTFE thread sealant to address common leakage issues in high-pressure and temperature-variant applications. The corrosion-resistant material and Schedule 40 construction prevent degradation from aggressive fluids like steam and oil, while the NPT threaded ends ensure airtight seals in piping networks for natural gas, water, and air. By combining welded durability with pre-applied sealing, it reduces maintenance downtime and installation errors in chemical processing, power generation, and HVAC systems, delivering long-term operational efficiency.

Specification Summary & Compliance

This pipe nipple adheres to ASME B1.20.1 for NPT thread dimensions and ASTM A733 for welded and seamless carbon and alloy steel pipe specifications, ensuring precise Class 2A thread tolerances. It is manufactured to meet RoHS 3 (2015/863/EU) compliance, with a size of 1 1/2" NPT, Schedule 40, and a length of 2 1/2" for consistent performance in industrial fittings.
