Nibco PCH61111X34X34 Press Tee 1x3/4x3/4 Copper Fitting

Product Description

The NIBCO PCH61111X34X34 is a copper press tee fitting designed for joining seamless copper tubing in residential and commercial piping systems. This reducing tee connects a 1-inch run with two 3/4-inch outlets using a press-fit connection, eliminating the need for soldering or open flame on the jobsite. A licensed plumber or pipefitter presses the fitting with a compatible pressing tool, and a unique N-shaped witness mark becomes visible on the fitting when the crimp is complete and properly seated. The design delivers a fast, reliable joint suitable for potable water, compressed air, and gas distribution lines.

This fitting is rated for use in residential and commercial applications including domestic water supply, compressed air systems, and gas piping. It is also approved for underground installation, making it a versatile choice for below-slab or buried copper runs. The press-fit method is especially useful in occupied buildings or tight spaces where torch work is restricted or hazardous. NIBCO PressG fittings cover a full range of copper and copper alloy press components, and this tee is part of that system-wide product family.
