Pipe Nipple for Air Gases Non-Potable Water Oils

The Beck steel pipe nipple connects sections of piping in systems carrying air, gases, non-potable water, or oils. It is manufactured in the USA from Grade B steel with a black anodized finish. The nominal pipe size is 1 1/4 inches with welded construction.

Threaded NPT Ends Allow Direct Assembly

Both ends feature NPT threads so the nipple threads directly into compatible fittings without additional adapters. The inside diameter measures 1 3/8 inches. Installers should apply appropriate thread sealant and avoid over-tightening to prevent thread damage or cracking.

Rated 300 psi at 150 Degrees F for Sustained Use

The nipple withstands a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 360 degrees F. These ratings apply to continuous service conditions rather than brief pressure spikes.

Questions about this item

How can I confirm the 12 in steel nipple is holding pressure after threading it into my 1 1/4 in NPT system?

Pressurise the line up to 300 psi at 150 °F or 150 psi steam at 360 °F and check every joint for leaks; the welded Grade B steel construction is rated for those limits.

What comes with the BECK 330032400 nipple and what must I supply myself?

The box contains only the 12 in black-anodised steel nipple with 1 1/4 in NPT threads on both ends; you must provide thread sealant, pipe wrenches and any mating fittings.

Which version of this nipple should I choose for a 1 1/4 in NPT air or oil line?

Select the 12 in length with 1 1/4 in nominal pipe size and NPT threads; it is the single configuration offered under part number 330032400.
