1/4" Schedule 40 black pipe nipple

This 1/4 inch male NPT nipple connects air, gas, non-potable water or oil lines in Schedule 40 steel piping systems. The welded steel construction with black finish suits industrial and mechanical installations. It is manufactured to fit standard Schedule 40 fittings and valves. The overall length is 3 inches with an outside diameter of 17/32 inch.

Pressure ratings and limits

The fitting handles a maximum operating pressure of 300 psi at 150 degrees F for general fluid service. For saturated steam applications the limit is 150 psi at 350 degrees F. These ratings define the safe envelope for air, gases, oils and non-potable water. Exceeding either pressure or temperature threshold risks joint failure or leakage.

Threaded male ends for Schedule 40 assembly

Both ends feature male NPT threads sized for 1/4 inch nominal pipe, allowing direct engagement with female Schedule 40 couplings, elbows or tees. The electric resistance weld provides a consistent seam along the barrel. No additional sealing components are included, so thread sealant or tape must be supplied by the installer. This nipple does not suit potable water systems or pressures beyond the stated ratings.

Questions about this item

Will the 1/4 inch MNPT threads on this Schedule 40 nipple match the fittings on my existing black steel pipe?

Yes, the male NPT threads follow the standard taper so they engage with any Schedule 40 female fitting of the same nominal size.

How can I verify the nipple is holding pressure after I thread it into my air line?

Pressurise the line to the working limit of 300 psi at 150 degrees F and check each joint for leaks with soapy water.

Does the package include thread sealant or do I need to buy tape and compound separately?

Only the steel nipple is supplied; you must provide PTFE tape or pipe dope for the threaded connections.
