Brass gate valve for residential water lines
This Milwaukee Valve UP668 is a 3/8 inch brass gate valve designed for sweat connection on water supply lines. It suits plumbers and homeowners installing or repairing low-pressure domestic plumbing systems.
Rated to 200 psi with a Cv of 10.7
The valve handles a maximum operating pressure of 200 psi and offers a flow coefficient of 10.7 for efficient water passage. Brass construction throughout the body, stem, wedge, seat and seal resists corrosion during normal service.
Sweat end fits 3/8 inch copper tube
A sweat connection on the inlet side joins directly to 3/8 inch copper tubing without threaded adapters. The non-rising stem and screw-in bonnet keep the installed height compact, freeing space in tight wall cavities or under fixtures.

Questions about this item
How do I sweat the 3/8" connection on the UP668 without damaging the brass seat?
Clean the copper tube and valve socket, apply flux, heat the joint evenly until solder flows into the cup, then cool naturally; overheating can soften the brass seat and cause leaks.
Will the forged brass wedge or stem packing need replacement on the UP668?
The solid forged brass wedge and brass stem are designed for the valve's service life; only the screw-in bonnet packing may require occasional tightening or repacking if a stem leak develops.
At what pressure does the UP668 reach its 200 psi rating during extended hot-water use?
The 200 psi rating is the maximum cold-water working pressure; sustained hot-water service reduces the safe limit, so system pressure should stay well below 200 psi at temperature.
