Description
Domestic Wrot Copper x Copper Reducing Coupling
Domestic wrot copper x copper reducing couplings connect two different sizes of copper tube in a straight soldered connection. Each fitting has two female copper sweat sockets, with one larger connection and one smaller connection, for transitioning between copper tube sizes in residential, commercial, plumbing, mechanical, maintenance, and repair applications.
Select the required reducing size from the product options above. Sizes are listed as large end x reduced end. The selected variation determines the Cello item number, online selling price, weight, cost, and other size-specific product information.

How a Reducing Copper Coupling Works
The larger socket accepts the larger copper tube, while the smaller socket accepts the reduced tube size. After both tube ends and fitting sockets are properly cleaned and prepared, the connections are assembled with approved flux and soldered to create a permanent straight transition between two different copper tube sizes.
How to Read the Size
Reducing coupling sizes are listed as large end x reduced end. For example, a 1" x 3/4" reducing coupling connects 1" copper tube on the larger end to 3/4" copper tube on the reduced end.

Frequently Asked Questions
What is a copper x copper reducing coupling used for?
It connects two different sizes of copper tube in a straight soldered connection.
How are the sizes listed?
Sizes are listed as large end x reduced end. For example, 2" x 1-1/2" connects 2" copper tube to 1-1/2" copper tube.
Do both ends have copper sweat connections?
Yes. Both ends are female copper sweat sockets designed for properly sized copper tube.
Is this a domestic copper fitting?
Yes. This product is listed as a domestic wrot copper pressure fitting.
Who manufactures this reducing coupling?
This product is manufactured by Cello Products.
How is the fitting installed?
Both copper tube ends and fitting sockets are cleaned, prepared with approved flux, assembled, and soldered according to accepted installation practices and applicable codes.
Is this the same as a straight coupling?
No. A straight coupling connects two equal-size copper tubes. This reducing coupling transitions between two different copper tube sizes.
Can this fitting be used for potable-water systems?
It may be used in compatible potable-water systems when installed according to applicable codes, standards, manufacturer requirements, and approved joining procedures.
Does the direction of installation matter?
The fitting can be oriented as required by the piping layout, but each tube must be inserted into the correctly sized socket.
