Beck 1-1/4" Schedule 40 Pipe Nipple

This black steel nipple measures 1-1/4 inches nominal size by 9-1/2 inches overall length. It is manufactured in the USA from Grade B welded steel with a black anodized finish. The component suits air, gas, non-potable water and oil lines rated for 300 psi at 150 degrees Fahrenheit or 150 psi steam at 360 degrees Fahrenheit.

For plumbing and industrial piping systems

Installers needing a Schedule 40 nipple for standard pressure service will find this part appropriate. It is not intended for potable water supply lines. Buyers who require a different nominal diameter, overall length or pressure class should select an alternative fitting.

Maximum operating pressure 300 psi at 150 degrees

This pressure and temperature rating determines whether the nipple matches the design limits of the piping system. Verify the service conditions against the 300 psi and 150 psi steam ratings before installation.

Questions about this item

What thread size and length does the 330031402 nipple need to connect to a 1-1/4" Schedule 40 fitting?

The nipple has a nominal pipe size of 1 1/4 in and an overall length of 9-1/2 in, with tapered NPT threads on both ends for Schedule 40 connections.

How do I install the 330031402 without cracking the cast-iron hub, and what torque step is commonly missed?

Clean threads, apply pipe dope or PTFE tape, hand-tighten, then wrench-tighten one to two turns — stopping before bottoming out avoids stressing the hub.

When should I replace the 330031402 nipple in a 300 psi air line?

Replace it if you see external corrosion, thread deformation, or leakage at the joints; the steel body is rated for 300 psi at 150 °F and 150 psi steam at 360 °F.
