  • Schedule 40 wall handles 1145 psi at 650 °F

1-1/4" x 5 ft Black Steel Pipe Nipple

This Schedule 40 Class 150 nipple is made from galvanized carbon steel with threaded ends on both sides. It suits plumbing installations that require a 1 1/4 inch nominal pipe size and a five foot overall length. The electric resistance weld construction provides a solid joint for standard piping runs.

Threaded MNPT ends and 1145 psi rating

The nipple connects via male NPT threads on each end and is rated for a maximum pressure of 1145 psi at 650 degrees Fahrenheit. This pressure and temperature limit defines the safe operating envelope for steam, water, oil, or gas lines. Exceeding these values risks joint failure or pipe deformation.

ANSI B 1.20.1 compliance

The pipe meets the ANSI B 1.20.1 standard for pipe threads, ensuring compatibility with matching fittings. Buyers who need a different thread standard, a larger diameter, or a higher pressure class will need an alternative product.

Questions about this item

Which length and diameter of this pipe nipple should I select for my project?

The nipple is supplied as a single 5 ft length with a 1-1/4 in nominal pipe size and MNPT threads on both ends.

What does the 1145 psi pressure rating mean when the nipple is installed in a working system?

It indicates the maximum allowable pressure at 650 °F; at lower temperatures the same Schedule 40 wall can handle the same or higher pressure.

How does the ANSI B 1.20.1 thread standard and Class 150 designation limit the fitting in practice?

The threads follow ANSI B 1.20.1 for MNPT compatibility, and Class 150 sets the pressure-temperature envelope for the nipple.
