3/4" x 1/2" FNPT Red Brass Reducing Coupling
This reducing coupling joins a 3/4 inch FNPT pipe to a 1/2 inch FNPT pipe. It is made from red brass for corrosion resistance in water supply systems. The fitting meets ANSI B 1.20.1, ASME B 16.15 and ASTM B584 standards. It suits residential and light commercial plumbing installations.
Class 125 Pressure Rating
The single specification that decides fit is the Class 125 rating with a maximum pressure of 125 psi. This defines the safe working limit for water, air or inert gas lines. Exceeding this pressure risks joint failure and leaks. Verify your system pressure stays below this value before installing.
Temperature Range -20 to 400 Degrees F
The coupling operates continuously from -20 to 400 degrees Fahrenheit without degrading the red brass body or thread seal. Thermal expansion remains predictable across this span, reducing stress on connected pipework. No active cooling or insulation is required for normal hot-water service. The material contains chemicals listed under California Proposition 65.

Questions about this item
What does the 125 psi pressure rating mean for everyday plumbing use?
The coupling is rated for 125 psi maximum working pressure, suitable for standard residential water supply lines operating well below that limit.
How does the FNPT thread standard affect compatibility with existing pipes?
FNPT tapered threads seal when tightened with thread tape or compound, matching any 3/4" or 1/2" NPT male fittings built to ANSI B1.20.1.
What clearance is needed to install this reducing coupling in a tight wall cavity?
The hex body requires a standard adjustable wrench; allow enough room to engage the flats and turn the fitting onto both male threads.
