Professional Applications & Engineering Value

This 1 1/4" Schedule 40 stainless steel pipe nipple solves critical connection challenges in industrial fluid handling systems. The 304/304L stainless steel construction provides exceptional resistance to corrosion and oxidation, making it ideal for steam applications, chemical processing, and oil and gas systems where material degradation is a concern. The unique threaded × butt weld configuration offers installation flexibility - the NPT threaded end allows for quick service connections while the butt weld end provides permanent, high-integrity joints for high-pressure applications. This dual-connection approach reduces system complexity and maintenance downtime in industrial piping networks handling air, water, and natural gas.

Specification Summary & Compliance
