Copper Reducing Tee 1-1/2 x 3/4

This wrot copper reducing tee connects a 1-1/2 inch copper tube to two 3/4 inch branches for potable water systems. It suits plumbers and DIY installers who need a sweat fitting with cup connections on all three sides. The specific fitting shape allows a smooth transition between different tube diameters.

Sweat Installation and Common Issues

Sweat the cup ends onto clean, fluxed copper tube using a propane or MAPP torch and lead-free solder. Ensure each joint reaches full temperature before applying solder so the alloy flows by capillary action. Overheating can anneal the copper and weaken the tube, while insufficient heat leaves voids that leak under pressure.

Check Tube Sizes and Local Codes

Verify that your existing tubing matches the 1-5/8 inch outer diameter on the run and 7/8 inch on both branches before ordering. Confirm that local plumbing codes permit copper sweat fittings for potable water in your jurisdiction. The item ships directly from the supplier and orders of 75 or more qualify for free shipping.

Questions about this item

How do I confirm the 611RR reducing tee is sealed correctly after soldering?

Pressurise the potable water line and inspect each cup joint for leaks; a dry, tight sweat connection on the 1 5/8 in and 7/8 in tube ends shows it is working.

What comes with the fitting and what must I supply?

The box contains the wrot copper reducing tee only; you must provide copper tube, flux, solder and a torch for the sweat connections.

Which 611RR size combination suits a 1 1/2 in main with two 3/4 in branches?

This model is the 1 1/2 x 3/4 x 3/4 in reducing tee, matching that exact run and outlet requirement.
