Copper

Copper fittings support commercial plumbing work involving copper tubing and compatible piping layouts. This category includes fittings for above-ground potable water supply and pressurized piping systems, as well as mechanical press connections for installation and repair work. Select from fittings that change direction, join tube, reduce line size, create branches or transition to a male threaded connection.

Helpful Buying Guide

Choose copper fittings for the connection your piping layout requires

Start with the job the fitting needs to perform: turn a run, join matching tube, transition between sizes, add a branch or connect copper press tubing to a male threaded component. Then confirm the connection method, end configuration, sizes and any stated minimum order before purchasing.

Use Cases

Build, modify or repair compatible copper piping

The represented fittings support above-ground potable water supply and pressurized piping work, along with copper tubing installation and repair. Available layouts address directional changes, straight connections, size changes, branch connections and press-to-MPT transitions.

How to Choose

Match fitting layout, size and joining method

Choose a long-radius elbow for a right-angle direction change, a coupling to join tube, a reducer for different sizes and a tee for a branch. Confirm whether the work calls for solder-joint ends or mechanical press ends, then match every stated connection size and configuration.

Applications

Plan around the piping run

Reducing couplings support transitions such as 1/2 in. to 1/4 in., 1/2 in. to 3/8 in., 1 in. to 3/4 in. and 3/8 in. to 1/4 in. Reducing tees create branches while maintaining the main run, including 3/4 in. x 3/8 in. x 3/4 in. and 2-1/2 in. x 2 in. x 2-1/2 in. layouts.

Additional Info

Review end styles and order quantities

Some fittings have specific end arrangements, including street x copper, three press ends and a press x MPT male adapter. Rolled stop couplings help position copper tube. Minimum orders vary among represented products, from 1 each to 350 each.

Planning Guide

Plan the right fit before choosing

Connection method

Choose solder-joint or press connections

Many represented wrot copper fittings use solder-joint connections for compatible copper piping. Copper press fittings support mechanical press joining, including a flameless joining option for copper tubing. A reducing press tee has three press ends, while the press x MPT male adapter provides a copper press connection on one side and a male threaded end on the other.

  • Use solder-joint fittings for compatible soldered copper piping work.
  • Use press fittings for compatible mechanical press joining.
  • Match threaded components to the stated MPT male end where applicable.
Fitting function

Select the shape that matches the piping change

Fitting geometry determines how the run is routed or connected. A 90-degree long-radius street elbow changes direction. Rolled stop couplings join compatible copper tube and help position it. Reducing couplings transition between two sizes, while reducing tees create a three-way branch with a reduced outlet.

  • Elbows route a pipe run through a right-angle change.
  • Couplings join compatible copper tube.
  • Reducers connect different copper line sizes.
  • Tees add a branch connection to a piping layout.
Size and purchasing planning

Verify every dimension and stated minimum order

Match the fitting's listed sizes to the copper tube or connection points in the installation. For example, tees may have a reduced branch size, and reducers have different sizes at each end. Also review stated minimum order quantities: some represented items are available with an effective minimum order of 1, while others list minimums of 100, 200, 250 or 350 each.

  • Check main-run and branch sizes separately on tees.
  • Confirm end configuration, such as street x copper, before ordering.
  • Plan project or stock quantities around the stated minimum order.
FAQ

Common questions before buying

What copper fitting should I use to change pipe direction?

A 90-degree long-radius street elbow is used for a right-angle change in direction.

What is a rolled stop coupling used for?

It joins compatible copper tube with a solder-joint connection and helps position the tube during installation.

How do reducing couplings differ from reducing tees?

A reducing coupling transitions between two line sizes, while a reducing tee creates a branch connection with a reduced outlet.

Are press and solder-joint fittings the same?

No. Solder-joint fittings support soldered installation, while press fittings support mechanical press joining; the represented press fitting also allows flameless joining.
