Black Steel Pipe Nipple for Air

This Beck C. H. 330029802 nipple joins 1-1/4 inch Schedule 40 piping in compressed-air, gas, oil or non-potable water systems. The welded Grade B steel body carries a black anodized finish and is rated for 300 psi at 150 Degrees F and 150 psi steam at 360 Degrees F.

Replaces Worn or Leaking Threaded Sections

When an existing nipple shows corrosion, thread damage or pressure loss, this component restores the sealed connection without changing pipe size or schedule. The upgrade is worth it whenever the original fitting can no longer hold the rated 300 psi service pressure.

Handles Rated Pressure with Headroom to Spare

The 1 3/8 inch inside diameter passes full flow for the nominal pipe size while the Grade B steel wall contains normal pressure spikes below 300 psi. It runs out of margin if system pressure exceeds the 300 psi limit or if steam pressure surpasses 150 psi at 360 Degrees F.

Questions about this item

What thread size and schedule rating does the 330029802 nipple require for a leak-tight fit?

The nipple is 1-1/4 inch nominal pipe size and Schedule 40, so it mates with standard NPT threads of the same size and schedule.

How should the black anodized steel nipple be installed, and what common step causes leaks?

Apply PTFE tape or pipe dope to the male threads, tighten hand-tight plus one to two turns with a wrench; skipping the sealant is the step that causes leaks.

When will the Grade B steel nipple need replacement under normal air, gas, oil or non-potable water service?

Replace if you see corrosion, thread deformation or leakage; the fitting is rated for 300 psi at 150 °F and 150 psi steam at 360 °F, so degradation depends on actual operating conditions.
