SKU CH-NGN6-4ERE6

Copper reducing tee joins 1-1/4, 3/4 and 1 inch tubes with sweat connections for potable water systems

  • Reduces pipe diameter from 1-1/4 in to 3/4 in and 1 in for versatile plumbing layouts
  • Wrot copper construction resists corrosion in potable water systems
  • Sweat cup connections on all three ends create strong soldered joints
  • Lead-free copper alloy meets safe drinking water standards
  • Compact reducing tee design saves space in tight installations

Copper Reducing Tee for Potable Water

This Nibco 611RR fitting joins three copper tubes of different diameters in a sweat connection. It suits plumbers and DIY installers working on residential water distribution. The reducing tee shape allows a smooth transition between supply and branch lines without additional adapters.

Wrot Copper Performance Under Pressure

The wrot copper body withstands continuous water pressure and temperature cycling in potable systems. Sweat joints create a permanent, leak-resistant seal once soldered. The material resists corrosion and scaling inside the pipe, maintaining flow capacity over the life of the installation.

Cup Connections and Daily Installation

Each outlet uses a cup end sized for standard copper tube outer diameters: 1 3/8 in, 7/8 in, and 1 1/8 in. The reducing layout means one fitting replaces multiple couplings, reducing joint count and solder time. Installers should verify tube clearance for torch access in tight cavities.

Questions about this item

Does the Nibco 611RR copper reducing tee generate any noise or heat when water runs through it all day?

The wrot copper tee is a passive fitting with no moving parts, so it produces no noise or heat of its own during continuous flow.

What copper tubing and tools must I already have to install the 1-1/4", 3/4" and 1" sweat connections?

You need matching copper tube in those three sizes, flux, lead-free solder and a propane or MAPP torch to sweat each cup joint.

Will the 611RR tee join directly to older copper pipe that has the same nominal sizes?

Yes, the cup ends accept standard copper tube outer diameters of 1-3/8", 7/8" and 1-1/8", which match existing pipe of those nominal sizes.
