4" Schedule 40 Galvanized Nipple

This galvanized steel pipe nipple provides a 4-inch nominal connection with male NPT threads on both ends. The close TBE design yields a compact 2 7/8-inch overall length for tight installations. It is rated for air, gas and potable water service in residential and commercial plumbing systems.

Electric Resistance Weld Construction

The nipple is manufactured using electric resistance welding for consistent joint integrity. A galvanized coating delivers corrosion resistance across the 4 1/2-inch outside diameter. The fitting conforms to Schedule 40 dimensions and is globally sourced to meet standard plumbing specifications.

Pressure Ratings and Limits

The fitting handles a maximum operating pressure of 300 psi at 150 degrees F for water, air and gas lines. Steam service is limited to 150 psi at 350 degrees F. It is not suited for pressures or temperatures beyond these published limits.

Questions about this item

Will the galvanized coating on this 4-inch Schedule 40 nipple need replacement due to corrosion over time?

The galvanized finish provides corrosion resistance for air, gas, and potable water applications, but the coating can wear or degrade depending on water chemistry and environmental conditions, eventually requiring pipe replacement.

What pressure limit will be reached first when this nipple handles hot water continuously at 350 degrees Fahrenheit?

The maximum steam pressure rating is 150 psi at 350 degrees F, which is lower than the 300 psi rating at 150 degrees F, so the steam limit governs under sustained high-temperature use.

Does this steel nipple generate noise or heat when water flows through it all day in a plumbing system?

The nipple itself is a passive welded steel fitting with no moving parts, so it produces no operational noise or heat; any sound or temperature change comes from the fluid and system design, not the fitting.
