1/4" NPT Steel Pipe Nipple

This 1/4 inch NPT pipe nipple connects air, gas, non-potable water, or oil lines in industrial or automotive plumbing systems. It is built from Grade B steel with a black anodized finish and welded construction. The fitting handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit and a maximum steam pressure of 150 psi at 360 degrees Fahrenheit.

Compatibility and installation checks

Verify that the mating components use 1/4 inch NPT threads before ordering. Confirm the 7/8 inch overall length fits the available space between fittings. Ensure the 23/64 inch inside diameter meets the flow requirements for the intended application. Check that the system operating pressure and temperature stay within the rated limits for the material.

Build quality and daily use

The Grade B steel body and welded seam provide structural integrity for demanding fluid transfer tasks. Black anodized coating adds corrosion resistance for longevity in harsh environments. Male NPT threads on both ends allow direct engagement with female threaded ports without additional adapters. Made in USA manufacturing supports consistent dimensional accuracy for reliable sealing.

Questions about this item

Does the 330005000 pipe nipple include any seals or thread tape, or must they be purchased separately?

The nipple is supplied as a single steel fitting with 1/4 inch NPT threads on both ends; any thread sealant or tape required for installation must be sourced separately.

Which length should I choose if the spec calls for a 7/8 inch close nipple in a 1/4 inch NPT line?

This model is the 7/8 inch overall length version made from Grade B steel with a 23/64 inch inside diameter, matching that exact requirement.

What does the 300 psi @ 150 Degrees F rating mean for an air or oil system running at shop temperature?

It certifies the welded steel nipple for continuous service up to 300 psi at 150 °F, with a separate 150 psi steam limit at 360 °F.
