Professional Applications & Engineering Value
This black-coated steel threaded pipe nipple delivers critical engineering solutions for industrial fluid and gas transfer systems. The welded construction combined with NPT threading creates reliable, pressure-tight seals that prevent leakage in demanding applications involving air, natural gas, oil, steam, and water. The Schedule 40 wall thickness provides optimal strength-to-weight ratio while maintaining flow capacity, making it ideal for connecting iron and steel fittings in Class 125 and 150 systems. The protective black coating significantly enhances corrosion resistance, reducing maintenance frequency and extending service life in harsh industrial environments where chemical exposure and moisture are common challenges.
Specification Summary & Compliance
This 1 1/4" Schedule 40 threaded pipe nipple features precision NPT threads manufactured to ASME B1.20.1 standards for reliable sealing performance. The product complies with ASTM A53 material specifications for steel pipe and ASTM A733 for welded and seamless carbon steel pipe nipples. With dimensions of 4 1/2" length, 1.38" ID, and 1 21/32" OD, this straight configuration pipe nipple maintains Class 2A thread tolerances for proper engagement with mating components. The construction meets industry standards for use with iron and steel fittings in pressure applications up to Class 150 flange ratings.
