Schedule 40 steel nipple for threaded pipe runs

This 1-1/4 inch by 4 inch black pipe nipple is made from Schedule 40 steel with threaded ends. It suits installers joining pipe sections in air, natural gas, non-potable water, oil or steam systems. The electric resistance weld construction provides a consistent bore for standard plumbing and industrial piping work.

Pressure and temperature limits for the fitting

The nipple is rated for a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 350 degrees F. These ratings define the safe envelope for the material and wall thickness. Systems that exceed either pressure or temperature require a different schedule or material.

Questions about this item

Should I pick the 1-1/4 inch by 4 inch Schedule 40 nipple or a different size?

Choose this nipple when your system calls for a 1-1/4 inch nominal pipe size, 4 inch overall length and Schedule 40 wall thickness; other diameters or lengths will not match the same threaded connections.

What does the 300 psi rating mean once the nipple is installed?

It indicates the maximum operating pressure for air, natural gas, non-potable water, oil or steam at 150 degrees F; exceeding that pressure or temperature can cause failure.

How does the threaded Schedule 40 connection limit what I can join?

The male NPT threads on both ends mate only with female Schedule 40 fittings of the same 1-1/4 inch nominal size, so you cannot directly connect different schedules or diameters without adapters.
