Questions about this item

What thread sizes does the 3/8" x 1/4" FNPT reducing coupling use?

The coupling has 3/8 in female NPT with 18 threads per inch on one end and 1/4 in female NPT with 18 threads per inch on the other.

How should the 304 stainless steel coupling be installed to avoid leaks?

Apply PTFE tape or pipe thread sealant to the male threads, then tighten the coupling by hand plus one to two turns with a wrench; over-tightening can crack the fitting.

When should the Class 3000 reducing coupling be inspected or replaced?

Inspect for corrosion, thread damage or leakage at each system service interval; replace the coupling if any cracking, galling or persistent weeping is found.
