• Durable welded design enhances structural integrity, minimizing failure risks under vibration or thermal cycling.
• Versatile fluid handling across multiple media including natural gas, oil, and steam, thanks to robust Schedule 40 wall thickness.
• Environmental and regulatory safety with RoHS 3 compliance, meeting global standards for hazardous substance restrictions.

Professional Applications & Engineering Value

This 316/316L stainless steel threaded pipe nipple addresses critical leakage and corrosion challenges in industrial piping systems. Its PTFE thread sealant is pre-applied to eliminate sealant misapplication, ensuring immediate leak-proof connections for air, natural gas, oil, steam, and water services. The corrosion-resistant material and welded construction withstand aggressive environments, such as chemical processing or offshore applications, while NPT threading (conforming to ASME B1.20.1) guarantees compatibility with standard fittings. Engineers benefit from reduced maintenance and extended service life in high-demand settings, from energy plants to HVAC systems, where reliability and compliance with ASTM A733 are paramount.

Specification Summary & Compliance

This nipple meets 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 from 316/316L stainless steel with a Schedule 40 wall thickness (OD: 1 21/32", ID: 1.38") and complies with RoHS 3 (2015/863/EU) for environmental safety, supporting use in regulated industries.
