Copper Reducing Tee 1.25 x 1.25 x 1 In

The Nibco C611 is a copper reducing tee designed to join three pipe sections in a T configuration. It features two 1.25 inch ends and a single 1 inch branch outlet. Copper construction provides durability and resistance to high temperature wear. This fitting suits plumbing systems requiring a secure branch connection.

Plumbers needing a durable branch fitting

This tee suits installers joining copper pipe of the specified sizes in hot or cold water lines. It is not for buyers who need a straight coupling or an elbow fitting. It is not for systems requiring different tube diameters or alternative material types. The specific reducing shape limits use to this exact size transition.

Simple sweat installation for copper pipe

Installation uses standard sweat soldering techniques compatible with copper tubing. Clean pipe ends and apply flux before heating the joint evenly. What usually goes wrong is insufficient heat causing a cold solder joint that leaks. Overheating can damage the fitting or pipe. Proper preparation ensures a watertight seal.

Questions about this item

What copper pipe sizes must already be in place for the C611 reducing tee to connect?

The tee joins two 1.25-inch copper lines with a 1-inch branch, so those three pipe ends must be present.

Will the C611 reducing tee fit alongside older copper plumbing of the same nominal sizes?

Yes, it matches standard 1.25-inch and 1-inch copper tubing dimensions used in existing installations.

How can I confirm the C611 reducing tee is seated correctly after soldering?

A full ring of solder visible at each of the three joints indicates a complete, leak-free connection.
