Professional Applications & Engineering Value

This 1" Schedule 40 stainless steel threaded pipe nipple with integrated PTFE thread sealant addresses critical industrial challenges by preventing fluid leakage in high-pressure systems. Engineered from 316/316L stainless steel, it resists pitting and corrosion from aggressive media like steam, oil, and natural gas, extending service life in chemical processing, oil and gas, and HVAC applications. The NPT threaded ends and welded construction ensure reliable performance under thermal expansion and mechanical stress, while the pre-applied sealant eliminates common installation errors. Ideal for connecting pipelines in air, water, and steam systems, this nipple reduces maintenance downtime and enhances system integrity where corrosion resistance and leak-proof sealing are paramount.

Specification Summary & Compliance

This product features precision NPT threading conforming to ASME B1.20.1 standards, ensuring dimensional accuracy and interchangeability. Manufactured according to ASTM A733 specifications for welded and seamless pipe, it maintains consistent Schedule 40 wall thickness and 3 1/2" length tolerances. The nipple is fully RoHS 3 (2015/863/EU) compliant, adhering to environmental regulations while supporting use in Class 150 systems with 316 stainless steel fittings and flanges.
