Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple delivers critical performance where corrosion resistance and pressure integrity matter most. The welded construction combined with NPT threading creates reliable, leak-resistant joints that maintain system safety when handling compressed air, natural gas distribution, hydraulic oil lines, steam transfer, or water systems. Engineered to Class 125 and 150 fittings, it prevents costly downtime in industrial plumbing, process piping, and energy transfer applications. The protective black coating significantly extends service life in humid or chemically aggressive environments, while the Schedule 40 wall thickness ensures burst resistance under fluctuating pressures. This straight pipe nipple solves connection challenges between iron and steel components across multiple industrial sectors.

Specification Summary & Compliance

This 1/4" NPT threaded pipe nipple features precision ASME B1.20.1 tapered pipe threads with Class 2A tolerance for secure mating. Manufacturing complies with ASTM A53 (standard for pipe, steel, black and hot-dipped, zinc-coated welded and seamless) and ASTM A733 (standard for welded and seamless carbon steel mechanical tubing). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations regarding hazardous substances, ensuring environmental responsibility and workplace safety standards.
