  • Galvanised coating resists corrosion for long service life

4 inch Schedule 40 Galvanized Steel Pipe Nipple

This nipple is a short length of galvanized steel pipe with male National Pipe Taper threads on both ends. It is designed for joining two female-threaded fittings in air, gas, non-potable water, oil or steam lines. The Schedule 40 wall thickness suits standard pressure requirements in industrial and commercial plumbing installations.

150 psi maximum operating pressure at 150 degrees F

The fitting is rated for 150 psi at 150 degrees Fahrenheit, which sets the practical limit for combined pressure and temperature in service. Galvanized coating provides corrosion resistance for the listed media but is not intended for potable water systems. Continuous welded construction maintains integrity under these specified operating conditions.

Replaces damaged or corroded threaded pipe sections

Use this nipple when repairing existing Schedule 40 galvanized piping where a 12 inch male-threaded connection is required. The jump is worth it when the surrounding system uses 4 inch nominal pipe size and threaded joints rather than flanged or welded connections. It does not suit systems requiring higher pressure ratings or different material grades.

Questions about this item

Should I choose the 12 inch length or a different size for my 4 inch Schedule 40 piping?

The 12 inch overall length suits standard spacing between 4 inch Schedule 40 fittings; select a different length only if your layout requires a longer or shorter nipple.

What does the 150 psi rating mean when the pipe is installed in a steam or air system?

It indicates the maximum operating pressure of 150 psi at 150 degrees Fahrenheit for air, gas, non-potable water, oil or steam service.

How does the male NPT threading work with Schedule 40 fittings and what pressure does it handle?

The male NPT threads mate with Schedule 40 female fittings and the joint is rated for the same 150 psi at 150 degrees Fahrenheit limit.
