1/2" Copper Dimple Stop Coupling

This wrot copper sweat fitting joins two 1/2 inch copper tubes using cup connections on both ends. A centre dimple stop keeps each tube seated at the correct depth during assembly. Rated for potable water systems, it handles up to 772 psi at 100 degrees F and 250 degrees F maximum temperature.

Installing the straight coupling

Clean tube ends and the fitting cups thoroughly, apply flux, then slide the coupling onto the tubes until each hits the centre dimple. Heat evenly with a propane or MAPP torch and feed lead-free solder into the joint until a complete fillet forms. Overheating can burn the flux and cause leaks, while insufficient heat leaves voids; both require cutting out and re-sweating the joint.

Check your system before ordering

Verify that the existing tubing is 1/2 inch copper with a 5/8 inch outer diameter so the cup connections match. Confirm the system pressure and temperature stay within the 772 psi at 100 degrees F and 250 degrees F limits. Ensure local codes permit sweat fittings for potable water and that you have the tools and skill to make reliable soldered joints.

Questions about this item

How can I verify the coupling is correctly installed and leak-free?

After soldering both 1/2 inch copper tubes into the cup ends, pressurise the line up to 772 psi at 100 Degrees F and inspect the dimple centre stop joint for any moisture.

What comes in the box and do I need extra materials?

The box contains only the W 10145 wrot copper coupling with its built-in dimple stop; you must supply 1/2 inch copper tube, flux, solder and a torch.

Which size should I choose for a standard 1/2 inch copper pipe?

Select the 1/2 inch nominal size — both ends accept 5/8 inch outer-diameter tube and are rated to 250 Degrees F maximum operating temperature.
