1-1/4" Schedule 40 black steel nipple
This 1-1/4 inch Schedule 40 black steel pipe nipple measures 2-1/2 inches overall length with a 1 21/32 inch outside diameter. It is designed for threaded connections in piping systems handling air, natural gas, non-potable water, oil or steam. The fitting is manufactured from welded steel with an electric resistance weld.
Pressure ratings at temperature
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 limits define performance under sustained load rather than brief pressure spikes. The black coating provides the standard finish for this schedule rating.
Thread compatibility and media checks
Verify that your existing piping uses matching 1-1/4 inch Schedule 40 threaded connections before ordering. Confirm the conveyed media is compatible with black steel and the stated pressure-temperature limits. Note the California Proposition 65 warnings regarding chemicals known to cause cancer and reproductive harm.

Questions about this item
How much heat can this black steel nipple handle when carrying steam all day?
It is rated for 150 psi saturated steam at 350 °F, so continuous high-temperature steam service stays within the published limit.
What thread standard must my existing pipe and fittings use to connect to this nipple?
Both ends are cut to NPT threads, so any Schedule 40 fitting with matching 1 1/4 inch NPT threads will screw on directly.
Will the 1 21/32 inch outside diameter fit through the same holes drilled for my older 1 1/4 inch nominal pipe?
Yes, the 1 21/32 inch OD matches the standard dimension for 1 1/4 inch nominal pipe, so existing clearance holes remain valid.
