Watts 0472031 Push-to-connect Tube Fitting 1/2 in Od

Product Description

The WATTS 0472031 is a push-to-connect tube-to-tube fitting designed for quick, tool-free connections between two tube ends. Constructed from brass with an EPDM O-ring, it accepts tubing with a 1/2 inch outside diameter on both ends. The fitting relies on a push-to-connect mechanism that grips and seals the tube without soldering, compression tools, or threaded assembly. It is well suited for plumbing, hydronic, and light mechanical systems where fast, reliable connections are required. Licensed plumbers and HVAC technicians commonly install this fitting during new construction, system repairs, or retrofits.

This fitting is used in residential and light commercial plumbing and hydronic heating applications where tube-to-tube inline connections are needed. The push-to-connect design makes it appropriate for tight spaces or situations where open-flame soldering is not permitted or practical. It is compatible with copper, CPVC, and PEX tubing at the specified outside diameter, as applicable to the fitting design.

Key Features

• Push-to-connect mechanism — no soldering, crimping, or threading required
• Brass body construction for durability and corrosion resistance
• EPDM O-ring provides a reliable seal at the connection point
• Accepts 1/2 inch OD tubing on both ends for inline tube-to-tube use
• Compact single-piece design suits confined installation spaces

Compatibility

Designed as an OEM-style push-to-connect replacement or new-installation fitting for inline tube-to-tube connections with 1/2 inch OD tubing in residential and light commercial plumbing and hydronic systems.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Before installing, shut off the water supply and relieve system pressure completely. Tubing ends should be cut square, deburred, and cleaned before insertion to ensure a proper seal. Verify local code compliance, including applicable IPC or IFGC requirements, before installing push-to-connect fittings in potable water systems.
