Professional Applications & Engineering Value
This black-coated steel pipe adapter solves critical connection challenges in industrial fluid handling systems. The welded construction combined with NPT threading on one end and butt weld/socket connection on the other enables seamless transitions between threaded and welded piping configurations. Engineered for air, natural gas, oil, steam, and water service, its Schedule 40 wall thickness (0.091") provides exceptional pressure rating capability while the protective coating resists corrosion in harsh operating environments. The adapter's straight design and precise 3/8" pipe size compatibility make it ideal for maintenance, repair, and new installation projects across petrochemical, manufacturing, and utility sectors where reliable pipe adapters are essential for system integrity.
Specification Summary & Compliance
This adapter features Class 2A NPT threads per ASME B1.20.1 standard with precise dimensional compliance to ASTM A53 and ASTM A733 specifications. The 4" length, 0.493" ID, and 43/64" OD maintain tight tolerances for reliable performance in iron and steel piping systems. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for global industrial applications.
