Watts 0472040 Push-to-connect Brass Reducing Tee Fitting

Product Description

The WATTS 0472040 is a push-to-connect brass tube-to-tube fitting configured as a reducing tee with outside diameter connections of 3/4 x 1/2 x 3/4 inches. It is designed for quick, tool-free assembly in potable water, hydronic, or general plumbing systems where reducing branch connections are required. The brass body provides corrosion resistance and durability, while the EPDM O-ring seal ensures a reliable, leak-free connection under normal service pressures. Licensed plumbers and HVAC technicians use this fitting when joining tubing of different diameters without soldering, threading, or crimping tools.

This fitting is suited for residential and light commercial plumbing applications including water distribution, radiant heating, and HVAC hydronic systems. The push-to-connect design allows for fast installation in tight spaces where torch access is limited or open-flame work is not permitted. It is appropriate for use with compatible copper, CPVC, or PEX tubing at the specified outside diameters. Always verify local code acceptance of push-to-connect fittings for the intended service before installation.

Key Features

• Push-to-connect design allows tool-free installation without soldering or crimping
• Brass body construction provides corrosion resistance for potable and hydronic water service
• EPDM O-ring seal delivers reliable, leak-resistant performance
• Reducing tee configuration joins 3/4 inch run tubing to a 1/2 inch branch in a single fitting
• Compact form factor suits installations in confined spaces or behind-wall rough-in work

Compatibility

Designed as an OEM-style push-to-connect replacement or new-install fitting for tube-to-tube connections with 3/4 x 1/2 x 3/4 inch outside diameter tubing in residential and commercial plumbing and hydronic systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the water supply and drain the line before cutting into existing piping. Ensure tubing ends are cut square, deburred, and cleaned before insertion to achieve a proper O-ring seal. Do not overtighten or force the fitting; the push-to-connect mechanism seats with firm hand pressure only.
