2" Copper Sweat Coupling for Water.

This straight coupling joins two 2-inch copper tubes using sweat connections on both ends. It is manufactured from wrot copper with an internal dimple stop that centres each tube during assembly. The fitting suits potable water, air and gas distribution in residential and commercial plumbing systems.

Pressure and Temperature Limits of the Copper

The coupling is rated for a maximum operating pressure of 364 psi at 100 degrees F and a maximum operating temperature of 400 degrees F. These figures define the safe envelope for the sweat joint itself; system design must stay within both limits simultaneously. Exceeding either value risks joint failure or accelerated degradation.

2-Inch Nominal Capacity with Dimple Stop Alignment

The 2-inch nominal bore handles typical residential and light-commercial flow rates for water, air and gas services. The built-in dimple stop provides a positive insertion depth so each tube seats fully before brazing, reducing the chance of under-insertion. Installations requiring larger diameters or press-fit connections will need a different fitting.

Questions about this item

Which size of this copper coupling should I select for a 2-inch copper tube?

Choose the 2-inch nominal size; both ends accept a 2 1/8-inch outer-diameter copper tube.

What does the 364 psi pressure rating mean once the fitting is installed?

It indicates the maximum operating pressure at 100 degrees Fahrenheit; the joint should not see higher pressure at that temperature.

What connection standard does this sweat fitting use and what does it limit?

It uses a cup-to-cup sweat connection for 2-inch copper tube, limiting the joint to 364 psi at 100 degrees Fahrenheit and 400 degrees Fahrenheit maximum temperature.
