Questions about this item

What thread sizes and class rating does the 1-1/4" x 3/4" FNPT reducing coupling require for installation?

The coupling uses 1-1/4 inch and 3/4 inch Female NPT threads at Class 125 for a secure fit.

How do I seal the NPT threads correctly, and what common mistake should I avoid?

Apply thread sealant or tape on the male threads only, then tighten to spec; over-tightening female NPT fittings often cracks the brass body.

When should I plan to replace this red brass reducing coupling in a typical water system?

Inspect annually for dezincification or leaks; replace if green patina, weeping joints, or pressure loss appear, especially near the 200 psi rating limit.
