Questions about this item

What thread size and length does the 3/8" NPT steel nipple need to fit my piping?

The nipple has 3/8" NPT threads on both ends and an overall length of 6 inches, with an inside diameter of 31/64 in for flow capacity.

How do I install this black anodized steel nipple without damaging the coating?

Apply PTFE tape or pipe dope to the male NPT threads, hand-tighten, then use a wrench on the hex flats for one to two turns; over-tightening can strip threads or crack the anodized finish.

When should I replace the nipple in a 300 psi air or oil system?

Replace it if you see corrosion, thread deformation, or leakage at the welded seam; the fitting is rated for 300 psi at 150 °F and 150 psi steam at 360 °F.
