This new reducing coupling connects 1-1/4 inch female NPT threads to 3/4 inch female NPT threads. The red brass construction meets Class 125 specifications for standard plumbing installations. It carries a maximum operating pressure rating of 200 psi.
Installers joining dissimilar pipe sizes
Suited for plumbers and maintenance crews transitioning between 1-1/4 inch and 3/4 inch NPT piping in water or compatible fluid systems. Not intended for applications requiring higher pressure ratings, different thread standards, or materials approved for potable water where local codes restrict lead content.
Maximum operating pressure 200 psi
The 200 psi pressure rating determines whether this coupling matches the system design pressure. Verify the service pressure does not exceed this limit before installation. The Class 125 designation aligns with the stated pressure capability.

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.
