Professional Applications & Engineering Value

This heavy-duty steel threaded pipe nipple solves critical connection challenges in industrial piping systems where leak prevention and media compatibility are paramount. The black-coated steel construction provides essential corrosion protection for long-term service in chemical exposure and outdoor installations. With NPT threading on both ends, it creates secure, pressure-tight joints between iron and steel fittings while accommodating thermal expansion in steam and hot water lines. The welded construction maintains structural integrity under vibration and pressure surges common in oil, gas, and compressed air systems. Engineered for Class 125 and 150 flange applications, this nipple delivers reliable performance across multiple industrial sectors including petrochemical, manufacturing, and utility distribution networks.
