Value Brand 1-1/4" MNPT x 5 ft. TBE Carbon Steel Pipe Nipple Sch 40

SKU CH-DG74-XPRA0

Threaded carbon steel pipe nipple, 5 ft length, Schedule 40 wall, 1145 psi rating at 650 °F

  • Galvanized carbon steel resists corrosion
  • Schedule 40 wall handles 1145 psi at 650 Degrees F
  • 380 in. inside diameter supports strong flow
  • Electric resistance weld ensures consistent joint strength
  • Meets ASTM A-53 and ASTM A-733 standards

5 ft. Schedule 40 Carbon Steel Pipe Nipple

This 5 ft. threaded nipple is made from galvanized carbon steel with electric resistance weld construction. It carries a Schedule 40 wall thickness and meets ASTM A-53, ASTM A-733 and WWN 351 standards. The pipe is metal detectable and rated for 1145 psi at 650 degrees F.

1-1/4 in. MNPT Threaded Connections

The nipple features male NPT threads on both ends with a nominal pipe size of 1-1/4 inches. The outside diameter measures 1.660 inches while the inside diameter is 1.380 inches. Wall thickness is 0.140 inches to maintain Schedule 40 dimensions.

Pressure Rating and Temperature Limit

The 1145 psi maximum pressure rating applies at the 650 degree F upper temperature limit. This combination suits high-pressure steam, compressed air and hydraulic lines within those bounds. Systems exceeding either the pressure or temperature threshold require a different specification.

Questions about this item

What does the 1145 psi rating at 650 °F mean when this nipple is installed in a steam line?

It is the maximum allowable working pressure at that temperature; the rating drops as temperature rises, so design the system to stay below 1145 psi at the highest expected steam temperature.

How do the MNPT threads on both ends limit the connection options?

Each end has male National Pipe Taper threads, so the nipple only mates with female NPT fittings such as couplings, elbows or valves; it cannot connect directly to another male-threaded component.

What clearance is required to fit the 1.660 in. outside diameter through a wall or support bracket?

The finished nipple measures 1.660 in. OD, so any penetration or hanger must provide at least that much clear opening plus space for thread engagement on both ends.
