3/4" Schedule 40 Galvanized Steel Nipple
This 3/4 inch nominal pipe size nipple is made from galvanized steel with a Schedule 40 wall thickness. It measures 4-1/2 inches overall length and features male NPT threads on both ends. The fitting is rated for 300 psi at 150 degrees F and 150 psi steam pressure at 350 degrees F. It suits air, gas, and potable water lines.
Installation notes for welded pipe nipple
The electric resistance weld construction provides a smooth bore for standard threading tools. Apply thread sealant rated for the system pressure and temperature before tightening. Over-tightening can distort the galvanized coating and create leak paths. Ensure mating fittings are also Schedule 40 to maintain consistent wall thickness and pressure rating.
Verify system requirements before ordering
Confirm the existing piping uses 3/4 inch NPT threads and Schedule 40 dimensions. Check that the 300 psi pressure rating at 150 degrees F meets the design conditions of the circuit. The galvanized finish resists corrosion but is not suitable for all chemical environments. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item
How do I verify the nipple holds pressure after threading it into a Schedule 40 fitting?
Pressurise the line to the 300 psi @ 150 °F rating and check for leaks at the male NPT threads; the electric-resistance weld and galvanized coating are designed for that working pressure.
What comes with the nipple and what must I supply?
The nipple itself is the only item included; you will need compatible Schedule 40 fittings, thread sealant or tape, and the appropriate wrenches for installation.
When should I choose this 4-1/2 inch overall length over other lengths?
Select this length when the piping layout calls for a 4-1/2 inch centre-to-centre span between Schedule 40 components in air, gas or potable water service.
