Plumbing Nipple for Air, Gas.

This Beck C. H. pipe nipple is a 1-1/4 inch nominal Schedule 40 steel component designed for air, gases, oils and non-potable water lines. The welded Grade B steel construction carries a black anodized finish and is rated for 300 psi at 150 degrees F and 150 psi steam at 360 degrees F. It suits installers needing a durable, USA-made conduit for industrial fluid transfer.

Replaces Worn or Leaking Threaded Steel Nipples

Use this nipple when an existing threaded steel connection shows corrosion, thread damage or seepage at the joint. The upgrade is worth it when the system operates near the 300 psi pressure rating or the 360 degrees F steam limit and the old fitting cannot guarantee a seal. It is not for potable water systems or installations requiring a different nominal diameter or pressure class.

Threads Directly Into Compatible 1-1/4 Inch Fittings

Installation requires clean, undamaged male threads on both mating fittings and a suitable pipe thread sealant rated for the service temperature. Common issues include cross-threading during hand-tightening, insufficient sealant causing leaks at pressure, and applying the nipple to incompatible pipe schedules or potable water circuits where the black coating is not approved.

Questions about this item

What nominal pipe size and schedule does the 330031204 nipple use for threading?

The nipple is manufactured to a nominal pipe size of 1 1/4 in and Schedule 40 wall thickness, so it threads into standard NPT fittings of the same size and schedule.

Which sealant should be applied to the tapered threads before tightening the 330031204 nipple?

Apply PTFE tape or pipe-thread compound to the male threads, then tighten until the joint is snug and leak-free; the common mistake is over-tightening, which can crack the fitting.

How often should the black anodized coating on the 330031204 nipple be inspected for corrosion?

Inspect the coating at least annually in air, gas, oil or non-potable water service up to 300 psi at 150 °F or 150 psi steam at 360 °F; replace the nipple if the finish shows rust or pitting.
