1/8 in MNPT x 8 in Galvanized Nipple

This 1/8 inch nominal Schedule 40 pipe nipple is built from welded steel with a galvanized coating for corrosion resistance. It carries a 300 psi rating at 150 degrees Fahrenheit for air, gas or potable water service. The 8 inch overall length and 13/32 inch outside diameter suit tight plumbing runs. California Proposition 65 warnings apply for cancer and reproductive harm.

Upgrade from shorter or uncoated nipples

A longer 8 inch reach replaces shorter fittings when extra thread engagement or clearance is needed. The galvanized finish upgrades plain steel where moisture or outdoor exposure would cause rust. The jump is worth it when the system demands Schedule 40 pressure integrity at 300 psi and 150 degrees Fahrenheit. Electric resistance weld construction ensures consistent joint strength.

300 psi capacity with 150 psi steam headroom

The nipple comfortably handles 300 psi water, air or gas pressure at 150 degrees Fahrenheit. For saturated steam service it provides 150 psi headroom at 350 degrees Fahrenheit. It runs out beyond those pressure and temperature limits or when a larger nominal bore is required. The 1/8 inch nominal size restricts flow volume in high-demand circuits.

Questions about this item

What thread size and length does the 1/8 in MNPT nipple need to fit?

It has a 1/8 in male NPT thread and an 8 in overall length with a 13/32 in outside diameter.

How do you seal the tapered MNPT threads without cracking the fitting?

Wrap PTFE tape clockwise on the male threads, hand-tighten, then turn one to two full turns with a wrench — overtightening splits the galvanized wall.

When should the nipple be replaced in a 300 psi water system?

Replace it if white rust appears, threads show galling, or the system sees pressure cycles above 300 psi at 150 °F.
