Professional Applications & Engineering Value
This galvanized steel threaded pipe nipple solves critical industrial challenges where corrosion resistance and pressure integrity are paramount. The NPT threaded both ends design creates secure, standardized connections that prevent leakage in compressed air systems, hydraulic lines, and process piping. Welded construction combined with Schedule 40 standard wall thickness provides exceptional burst resistance for oil, gas, and steam applications. The zinc coating actively protects against rust in humid environments and water systems, while meeting Class 125/150 flange requirements ensures compatibility with existing industrial infrastructure. Engineers specify this fitting for its reliable performance across multiple media without cross-contamination risks.
Specification Summary & Compliance
Manufactured to ASME B1.20.1 specifications for precise NPT threading with Class 2A tolerance, ensuring proper engagement with mating components. The galvanized steel material complies with ASTM A53 for pipe quality and ASTM A733 for welded and seamless carbon steel tubing. Dimensions include 3/8" NPT threads, 2-1/2" length, 0.493" ID, and 43/64" OD with 0.091" wall thickness. Suitable for systems requiring compliance with pressure class 125 and 150 standards.
