ZORO SELECT 5P633 Pipe Nipple

This ZORO SELECT pipe nipple is a Schedule 40 steel fitting with a 3/8 in nominal pipe size and a 1 in overall length. It suits installers routing air, natural gas, non-potable water, oil or steam in threaded piping systems. The close-thread connection on Side A allows direct engagement with compatible female-threaded components. Buyers needing a different length or a larger nominal size should select an alternative fitting.

Thermals Noise and Power Draw

The nipple is rated for a maximum operating pressure of 300 psi at 150 Degrees F and a maximum steam pressure of 150 psi at 350 Degrees F. Its welded steel construction contains the fluid without generating heat, noise or electrical draw. Systems operating beyond these pressure or temperature limits require a fitting with higher ratings.

Build Quality and Connectors

The fitting is manufactured from globally sourced steel with a black finish and electric resistance weld construction. Its outside diameter measures 43/64 in, matching Schedule 40 dimensions for standard compatibility. California Proposition 65 notices indicate the product contains chemicals known to cause cancer and birth defects or other reproductive harm. Installers should verify thread sealant suitability for the intended media.

Questions about this item

How do I install the 3/8 in Schedule 40 nipple without stripping the close threads?

Apply PTFE tape or pipe dope to the male threads, then hand-tighten before using a wrench on the 43/64 in outside diameter hex area; over-torquing the short 1 in length is the common mistake.

Will the black steel finish need recoating or replacement after long service?

The black coating resists corrosion on air, natural gas, non-potable water, oil and steam lines; inspect annually for rust or thread damage and replace the nipple if wall loss appears.

What pressure-temperature limit will I hit first on a continuous steam run?

The 150 psi @ 350 °F steam rating is lower than the 300 psi @ 150 °F water rating, so sustained steam service reaches its ceiling first.
