Copper Reducer for 4" and 2" Tube
The Nibco 600R is a straight reducing coupling made from wrot copper. It joins a 4 in nominal tube to a 2 in nominal tube using sweat connections on both ends. Plumbers and mechanical contractors use it for air, gas or potable water lines where a diameter transition is required.
Pressure and Temperature Limits
The fitting is rated for a maximum operating pressure of 293 psi at 100 Degrees F and a maximum operating temperature of 400 Degrees F. Systems that exceed either value need a different component. The rating applies to the coupling itself; the completed joint also depends on the solder alloy and the installer's workmanship.
Sweat Installation and Common Issues
Installation requires cleaning both tube ends, applying flux and sweating the joint with a torch. Overheating can anneal the copper and weaken the fitting. Insufficient heat leaves voids in the solder that leak under pressure. Misaligned tubes stress the joint and reduce its service life.

Questions about this item
Which size of the 600R reducer fits my 4 in and 2 in copper lines?
The 600R 4x2 model connects a 4 in copper tube (4 1/8 in OD) to a 2 in copper tube (2 1/8 in OD) with cup ends on both sides for sweat soldering.
What does the 293 psi rating mean when the fitting is in service?
It is the maximum operating pressure at 100 Degrees F; the joint must not see higher pressure at that temperature.
How does the sweat cup connection limit the installation?
Both ends are cup fittings for sweat soldering to copper tube; no threaded or press options are included.
