Zoro Select 4 Inch Aluminum Pipe Nipple

This Zoro Select pipe nipple is a Schedule 40 fitting made from 6063-T6 aluminum. It features male NPT threads on both ends with a nominal size of 4 inches and an overall length of 2 7/8 inches. The seamless construction provides corrosion resistance for air applications with a maximum operating pressure of 125 psi at 72 degrees Fahrenheit.

Suits Air Lines Needing NPT Connections

This nipple suits installers joining two female NPT ports in a 4 inch Schedule 40 aluminum air system. It is not for plumbing carrying fluids above the rated pressure or temperature. Builders requiring a different nominal size, thread standard, material grade, or overall length should look at other fittings.

4 Inch Nominal Size With 2 7/8 Inch Length

The nominal pipe size of 4 inches combined with the 2 7/8 inch overall length determines whether this specific nipple bridges the gap in your assembly. Verify both dimensions against your system layout before ordering to ensure correct fitment.

Questions about this item

What NPT thread size must the existing pipe or fitting have to connect to this 4 in nipple?

Both ends use 4 in NPT male threads, so the mating component needs a matching 4 in NPT female opening.

Can this Schedule 40 aluminum nipple handle the same 125 psi pressure as the steel pipe already in the system?

Yes, it is rated for 125 psi at 72 °F, matching the pressure class of Schedule 40 piping.

How can I confirm the nipple is seated correctly after threading it into both fittings?

The overall length is 2 7/8 in and the outside diameter is 4 1/2 in; verify those dimensions once both NPT connections are fully engaged.
