• Welded construction with Schedule 40 wall thickness delivers superior structural integrity for high-pressure applications involving air, gas, oil, steam, and water
• NPT threading on both ends creates reliable, standardized connections with compatible fittings while preventing cross-threading issues
• 12-inch length with precise dimensional control enables flexible installation in tight spaces and complex piping configurations
• Compliance with ASME B1.20.1 and ASTM A733 standards guarantees consistent quality, dimensional accuracy, and performance reliability
• RoHS 3 compliance ensures environmental responsibility and meets international regulatory requirements for industrial applications

Professional Applications & Engineering Value

This 304/304L stainless steel threaded pipe nipple with integrated PTFE thread sealant solves critical sealing challenges in industrial fluid and gas handling systems. The welded construction combined with Schedule 40 wall thickness provides exceptional burst pressure resistance for demanding applications involving steam, natural gas, oil, air, and water. The factory-applied PTFE sealant eliminates common installation errors associated with manual tape application, ensuring immediate pressure-tight seals that withstand thermal cycling and vibration. Engineered with NPT threads on both ends, this 12-inch pipe nipple maintains consistent sealing performance across temperature fluctuations while the stainless steel material resists corrosion in harsh environments, reducing maintenance frequency and system downtime.

Specification Summary & Compliance

This 1/2" NPT threaded pipe nipple features precision NPT threading per ASME B1.20.1 standards with Class 2A tolerance for reliable engagement. Manufactured from 304/304L stainless steel meeting ASTM A733 specifications for welded and seamless pipe, it maintains dimensional accuracy with 0.622" ID, 27/32" OD, and 0.109" wall thickness. The product is RoHS 3 (2015/863/EU) compliant and suitable for Class 150 fittings and flanges in various industrial piping systems.
