1-1/4" Schedule 40 Black Steel Nipple

This 1-1/4 inch nominal black steel pipe nipple measures 4.5 inches overall and carries Schedule 40 wall thickness. Both ends feature male NPT threads for standard threaded connections. It meets ASTM A-53 Type E and ASTM A-733 Grade B standards. The welded construction uses electric resistance weld pipe.

Check thread size and pressure rating

Verify that your system uses 1-1/4 inch NPT threads before ordering. The fitting is rated for a maximum pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi WSP. Ensure the 1/8 inch wall thickness and 1 21/32 inch outside diameter suit your piping layout.

Suits water, gas and steam lines

This nipple suits installers needing a short, threaded black steel connector for Schedule 40 piping systems. It is not for buyers who require a different nominal diameter, a longer or shorter overall length, or a fitting with a different thread type or pressure class.

Questions about this item

Does the nipple come with any sealant or gaskets, or must I buy thread tape separately?

The nipple is supplied as a single threaded steel piece; pipe-thread sealant or tape is not included and must be purchased separately.

Why choose a Schedule 40 nipple in 1-1/4" nominal size rather than a different wall thickness?

Schedule 40 provides a 1/8 in wall thickness rated for 300 psi at 150 °F and 150 psi steam, matching standard residential and light-commercial black-steel piping requirements.

What does the 300 psi pressure rating mean when the nipple is installed in a hot-water heating loop?

At the maximum service temperature of 150 °F the nipple is rated to hold 300 psi continuously, so typical hydronic heating pressures well below that are safely contained.
