Beck C. H. 0330056003 Pipe Nipple 4 in NPTxNPT 10 in

SKU CH-5GGW-G66X5

A 10-inch steel pipe nipple with 4-inch NPT threads on both ends, rated for 300 psi at 150 degrees F and 150 psi steam at 360 degrees F, made in the USA

  • Product colorTransparent
  • Ready for air, gas, oil or non-potable water lines
  • Rated 300 psi at 150 °F for high-pressure duty
  • Withstands 150 psi steam at 360 °F
  • Welded Grade B steel construction made in USA
  • 10 in overall length with 4 in NPT threads

Application Scope

This 4 inch NPT pipe nipple connects air, gas, non-potable water and oil lines in industrial piping systems. The steel construction with black anodized finish handles welded installations where a 10 inch length is required.

Upgrade Path

It replaces shorter nipples or fittings with incompatible thread types when a longer welded steel section rated for 300 psi at 150 degrees F is needed. The jump is worth it when the system demands Grade B steel and a manufactured in USA provenance.

Sustained Load Behavior

Under continuous pressure the nipple maintains integrity up to its 300 psi rating at 150 degrees F and 150 psi steam pressure at 360 degrees F. The welded Grade B steel construction resists deformation during extended thermal and hydraulic cycling.

Questions about this item

What size wrench fits the 4 in NPT threads on this 10 in steel nipple?

Use a 4 in pipe wrench or adjustable jaw wide enough for the 4 1/64 in outside diameter; the welded Grade B steel body handles the torque without deforming.

Which step do installers often skip when threading this nipple into a female NPT fitting?

They forget to wrap the male threads with PTFE tape or pipe dope before tightening, which risks leaks at the 300 psi / 150 °F air, gas, oil or non-potable water rating.

When should the black anodized finish be inspected or the nipple replaced?

Check for coating wear, corrosion or thread damage during routine system maintenance; replace if the finish is breached or after any over-pressure event above 300 psi.
