Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple solves critical sealing and durability challenges in industrial fluid systems. The welded construction combined with NPT threading on both ends creates reliable, pressure-tight connections that withstand thermal cycling and mechanical stress. Engineered for air, natural gas, oil, steam, and water applications, the protective coating prevents corrosion in humid or chemical-exposed environments. The Schedule 40 standard-wall thickness provides optimal burst resistance while maintaining flow efficiency, making it ideal for 125 and 150 class fittings in processing plants, mechanical rooms, and industrial machinery.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 thread standards with material specifications meeting ASTM A53 and ASTM A733. Features precise NPT threading on both ends with 1/8" pipe size and 0.068" wall thickness. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring safe handling and environmental responsibility.
