Professional Applications & Engineering Value

This black-coated steel threaded pipe nipple solves critical sealing and durability challenges in industrial fluid handling systems. The welded construction combined with NPT threading creates a robust connection point that maintains integrity under varying pressure conditions across air, natural gas, oil, steam, and water applications. Engineered to ASME B1.20.1 standards, the precision threads eliminate leakage concerns while the Schedule 40 wall thickness provides optimal pressure containment. The protective black coating significantly enhances corrosion resistance, making it ideal for harsh environments where chemical exposure or moisture could compromise ordinary fittings. This heavy-duty pipe connector delivers reliable performance in processing plants, utility distribution systems, and industrial machinery where failure is not an option.

Specification Summary & Compliance

This 1 1/4" Schedule 40 threaded pipe nipple features NPT (National Pipe Taper) threads conforming to ASME B1.20.1 specifications for dimensional accuracy and thread form. Manufactured from steel meeting ASTM A53 and ASTM A733 standards, it ensures consistent material properties and performance characteristics. The product maintains standard Class 2A thread tolerances for proper engagement with compatible fittings. With 3-inch length, 1.38" ID, and 1 21/32" OD, it provides precise dimensional consistency for seamless integration into industrial piping systems designed for 125 and 150 class fittings.
