3/4" x 9" Black Steel Pipe Nipple

This Schedule 40 nipple is made from black steel with male NPT threads on both ends. It measures 9 inches overall with a 3/4 inch nominal pipe size and 7/64 inch wall thickness. The fitting meets ASTM A-53 Type E and ASTM A-733 Grade B standards for pressure piping applications.

Suitable uses and limits

This nipple suits installers joining two female-threaded components in water, oil, or gas lines rated up to 300 psi at 150 degrees Fahrenheit. It is not for systems requiring higher steam pressure than 150 psi WSP or for potable water lines needing lead-free certified fittings. Builders needing a different length or diameter should select another size.

Pressure and temperature rating

The maximum working pressure is 300 psi at 150 degrees Fahrenheit, with a steam rating of 150 psi WSP. This pressure class determines whether the nipple matches the design limits of the piping system. Verify the system pressure and temperature against these ratings before installation.

Questions about this item

Does this nipple need a specific pipe sealant for its MNPT threads?

Can I join this Sch 40 nipple to an existing Sch 80 black steel line?

Yes, the 3/4 inch MNPT threads match, but the system pressure is limited to this nipple's 300 psi rating.

How do I confirm the nipple meets ASTM A-53 Type E and Grade B after installation?

Check the pipe body for the ASTM A-53 Type E and Grade B markings required by the standard.
