  • Handles air, gas, oil, steam and non-potable water
  • Welded steel construction rated for 300 psi at 150 °F
  • Schedule 40 wall thickness suits standard piping systems
  • 10-inch overall length with 1 1/2-inch NPT threads both ends
  • Black-coated finish resists corrosion in industrial environments

Application Range

This steel pipe nipple handles air, natural gas, non-potable water, oil and steam in Schedule 40 systems. The nominal size is 1 1/2 inches with NPT threads on both ends for direct connection to compatible fittings.

Build and Connections

The welded steel body has a black finish and an outside diameter of 1 57/64 inches. Electric resistance weld construction and a 10 inch overall length suit standard Schedule 40 piping layouts with threaded joints.

Upgrade Context

It replaces a shorter or damaged nipple when a 10 inch span is required at 300 psi maximum operating pressure or 150 psi steam pressure. The jump is worth it only when the longer reach and pressure rating match the existing Schedule 40 specification.

Questions about this item

What pressure does the NPT threading on this 1 1/2 inch nipple handle in daily use?

The Schedule 40 steel nipple is rated for 300 psi at 150 degrees F and 150 psi saturated steam at 350 degrees F, so the NPT threads hold those limits when assembled correctly.

What clearance and thread engagement does the 1 1/2 inch NPT end need to seal?

The nipple measures 1 57/64 inches outside diameter and 10 inches overall; each NPT end requires full thread engagement plus a compatible Schedule 40 female fitting to seat without bottoming out.

How do I install this welded steel nipple without creating a leak path?

Apply pipe thread sealant or tape on the male threads only, tighten two turns past hand-tight with a wrench on the hex flats, and avoid over-torquing which distorts the welded Schedule 40 wall.
