Professional Applications & Engineering Value

This 304 stainless steel threaded pipe nipple delivers critical sealing reliability for industrial fluid and gas transfer systems. The PTFE thread sealant is factory-applied to eliminate common leakage points in NPT threaded connections, particularly valuable in thermal cycling applications with steam or hot oil where thread compound degradation can cause failures. Its welded construction and Schedule 40 wall thickness provide exceptional resistance to pressure surges and mechanical stress in air, natural gas, oil, steam, and water systems. The corrosion-resistant 304/304L stainless steel material ensures longevity in humid or chemically aggressive environments, making it ideal for chemical processing, power generation, and industrial plumbing applications where leak-proof performance is non-negotiable.

Specification Summary & Compliance

This 1/2 inch NPT threaded pipe nipple features precision NPT threading manufactured to ASME B1.20.1 standards for consistent engagement and sealing performance. The component meets ASTM A733 specifications for welded stainless steel pipe with Schedule 40 dimensions (0.622" ID, 27/32" OD, 0.109" wall thickness). Manufacturing compliance includes RoHS 3 (2015/863/EU) environmental directives, ensuring restriction of hazardous substances for international projects. The 2-1/2 inch length and male threaded both ends configuration provides versatile connection capability within Class 150 pressure rating systems.
