1/4 in Schedule 40 Black Steel Nipple

This 1/4 inch nominal Schedule 40 pipe nipple is made from black steel with male NPT threads on both ends. It measures 5 inches in overall length and has a 5/64 inch wall thickness. The fitting is designed for threaded pipe connections in plumbing and industrial piping systems.

Verify thread type and pressure rating

Confirm that your existing piping uses 1/4 inch male NPT threads to match the MNPT x MNPT connections on this nipple. The maximum working pressure is 300 psi at 150 degrees Fahrenheit and the maximum steam pressure is 150 psi WSP. Ensure your system operating conditions stay within these limits.

Welded construction handles sustained pressure

The nipple uses electric resistance welded construction meeting ASTM A-53 Type E and ASTM A-733 Grade B standards. This welded seam maintains structural integrity under continuous pressure up to the rated 300 psi. The black steel material provides durability for long-term installation in compatible fluid or gas lines.

Questions about this item

What comes in the box and do I need to buy thread sealant separately?

The box contains one black steel pipe nipple with male NPT threads on both ends. Thread sealant or tape is not included and must be purchased separately for a leak-free seal.

Should I choose this 5 in length or a different size for my 1/4 in nominal pipe system?

Choose this 5 in overall length when the gap between two female-threaded fittings matches that dimension; other lengths are available for different spacing requirements.

What does the 300 psi rating mean when the nipple is installed in a water line at 150 °F?

It indicates the maximum working pressure of 300 psi at 150 °F for water, oil or gas service; for steam the limit is 150 psi WSP.
