3-inch Schedule 40 galvanised pipe nipple

This new ZORO SELECT nipple is a 3-inch nominal-size steel fitting with male NPT threads on one end and a plain-threaded end on the other. It is rated for 300 psi at 150 degrees F and 150 psi steam at 350 degrees F. The electric-resistance-welded construction and galvanised coating provide corrosion resistance for air, gas and potable-water lines.

Galvanised coating and welded construction

The zinc finish protects the steel from rust in damp or outdoor installations, while the Schedule 40 wall thickness handles the stated pressure ratings. Electric resistance welding creates a consistent seam along the 6-inch overall length. These features suit general-purpose plumbing and compressed-air systems that require a durable, coated steel nipple.

Check thread compatibility and chemical warnings

Verify that the mating fittings accept 3-inch male NPT threads and that the system pressure stays within the 300 psi limit at 150 degrees F. The product carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm, so review local regulations before installing in potable-water applications.

Questions about this item

Will the galvanized coating need replacement if used with potable water?

The galvanized finish resists corrosion, but the product carries a Proposition 65 warning for chemicals linked to cancer and reproductive harm, so periodic inspection is advised.

What pressure limit will be reached first under continuous hot-water service?

At 150 °F the maximum operating pressure is 300 psi, while steam service is limited to 150 psi at 350 °F, so the lower steam rating governs if temperatures rise.

Does the pipe nipple generate noise or heat when water flows through it all day?

As a passive steel fitting it produces no noise or heat of its own; any sound or temperature rise comes from the fluid and pump, not the nipple.
