1/4 NPT Steel Pipe Nipple

This 4 1/2 inch steel pipe nipple connects air, gas, non-potable water and oil lines using male NPT threads on both ends. It meets Schedule 40 dimensions for standard plumbing and industrial piping systems. The welded construction handles pressures up to 300 psi at 150 degrees Fahrenheit and steam up to 150 psi at 350 degrees Fahrenheit.

Schedule 40 Welded Construction

Electric resistance welding creates a consistent seam along the steel body with a black finish for corrosion resistance. The 1 7/32 inch outside diameter matches Schedule 40 specifications for compatibility with standard fittings. Male threads on both sides allow direct connection to female-threaded couplings, valves or equipment ports without additional adapters.

Globally Sourced Component

The nipple arrives as a single finished fitting ready for thread sealant and installation. No gaskets, seal tape or specialized tools are included in the package. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm. Buyers needing potable-water rated or stainless steel alternatives should select a different product.
