Nibco, Inc. 600R Wrot Copper Reducing Coupling 3/4 x 3/8

SKU CH-PGZA-XJ1QZ

Wrot copper reducing coupling joins 3/4-inch to 3/8-inch tubing with a solder connection, rated to 582 psi at 100°F

  • TypePlumbing & Pipe Fittings
  • Reduces tube size from 3/4 in to 3/8 in with C x C connections
  • Wrot copper construction handles 582 psi at 100 Degrees F
  • Operates reliably across -20 Degrees to 400 Degrees F temperature range
  • Meets ASME/ANSI B 16.22 standard for plumbing fittings
  • Integrated stop ensures proper tube insertion depth during installation

Copper Reducing Coupling 3/4 x 3/8

This wrot copper fitting joins a 3/4 inch tube to a 3/8 inch tube using C x C solder connections. It meets ASME/ANSI B 16.22 standards for plumbing and pipe fittings. The built-in stop ensures correct insertion depth during assembly.

Built-in Stop and Pressure Rating

The internal stop prevents the smaller tube from sliding too far into the larger end, simplifying alignment while soldering. The coupling withstands 582 psi at 100 degrees F and operates continuously from -20 to 400 degrees F. Wrot copper construction resists corrosion in potable water and hydronic systems.

For Copper Tube Reduction Jobs

Suited for plumbers and HVAC technicians reducing 3/4 inch copper tube to 3/8 inch in water supply, heating or cooling lines. Not for installers who need press-connect, push-fit or threaded ends instead of solder joints. Buyers requiring a different tube-size combination should select another fitting.

Highlights

  • Reduces tube size from 3/4 in to 3/8 in with C x C connections

Questions about this item

Will the wrot copper body need replacement if the system runs near the 400 Degrees F limit?

The coupling is rated to 400 Degrees F; prolonged exposure at that temperature may accelerate oxidation, so plan to inspect joints during routine maintenance.

Does the 582 psi rating at 100 Degrees F drop first under sustained high-temperature operation?

Pressure capacity decreases as temperature rises toward 400 Degrees F, so the temperature limit becomes the governing constraint before the pressure rating is reached.

How much heat does the 3/4 x 3/8 coupling add to a pipe run that operates all day?

The copper fitting itself generates no heat; it simply conducts the fluid temperature, so insulation should be sized for the pipe's operating temperature.
