  • Threaded NPT ends connect air, gas, oil and non-potable water lines
  • Schedule 40 steel rated 300 psi at 150 °F and 150 psi steam at 350 °F
  • Electric resistance welded construction for leak-resistant joints
  • 1 1/2 in nominal size with 2 in overall length fits standard fittings
  • Black finish protects steel during storage and installation

Steel Pipe Nipple 1 1/2 Inch NPT

This steel pipe nipple connects threaded components in air gas non-potable water and oil lines. It suits installers who need a short Schedule 40 fitting with male NPT threads on both ends. The welded construction provides a solid joint for standard plumbing and industrial assemblies. Buyers who require a longer length or a different nominal size will need another fitting.

Sustained Pressure Rating 300 PSI

The fitting holds up to 300 psi at 150 degrees F for continuous liquid or gas service. Steam duty is rated at 150 psi at 350 degrees F so the same piece can handle both roles within those limits. Electric resistance weld seams maintain integrity under steady loads without the fatigue that can appear in lighter walls. Systems that exceed either pressure or temperature envelope must use a heavier schedule.

Schedule 40 Threaded Interface

Male NPT threads on each end mate with standard female fittings valves or equipment ports. The 1 57/64 inch outside diameter matches Schedule 40 dimensions so it fits existing piping without adapters. California Proposition 65 notices apply because the steel contains listed chemicals. Installers who need a different thread standard or a socket weld end cannot use this nipple.

Questions about this item

Does the steel nipple generate heat or noise when air or oil flows through it at 300 psi?

The nipple is a passive steel fitting with no moving parts, so it produces no noise or heat of its own; any temperature rise comes from the fluid itself.

What thread sealant or tape do I need to make the 1 1/2 in NPT connections leak-free?

The male NPT threads on both ends require PTFE tape or pipe-thread sealant rated for 300 psi service to seal properly.

Will this Schedule 40 nipple mate with the older Schedule 40 black-iron pipe I already have in the shop?

Yes, the 1 1/2 in nominal size and Schedule 40 wall match standard black-iron pipe, so the threads engage directly.
