This 3/8 inch nominal pipe size nipple is made from Grade B welded steel with a galvanized finish. It suits air, gas and potable water lines in residential or light commercial plumbing work. The Schedule 40 wall provides standard pressure containment for these services.

MNPT Threads & Class 150 Rating

Male NPT threads on both ends allow direct connection to female threaded fittings without additional adapters. The Class 150 compatibility and 1739 psi maximum operating pressure at 650 degrees Fahrenheit cover typical low pressure steam and water systems. Operating range spans -20 to 600 degrees Fahrenheit.

8 Inch TBE Length & Prop 65 Notice

The 8 inch thread both ends length fits common spacing between fixtures or equipment. No gaskets, sealant or tools are included so installers must supply thread tape or pipe dope. California Proposition 65 warnings apply for cancer and reproductive harm from contained chemicals.

Questions about this item

What does the 3/8" MNPT thread limit in pressure and temperature?

The 3/8" MNPT connection is rated for 1739 psi at 650 Degrees F for air, gas and potable water service.

What clearance does the 8" TBE nipple need for installation?

The nipple measures 8 inches thread-to-thread with a 31/64 inch inside diameter and requires Class 150 fitting compatibility.

How do you seal the tapered threads without cracking the galvanized coating?

Apply PTFE tape or pipe dope on the male threads only, hand-tighten then turn one to two full turns with a wrench; over-tightening splits the coating and causes leaks.
