3/8" Bronze Gate Valve

The Milwaukee Valve 1140 is a 3/8 inch bronze gate valve designed for controlling the flow of gas, oil, or water in plumbing and industrial systems. It features a solid bronze wedge and screw-in bonnet for durable shut-off performance in compatible piping networks.

Class 150 Pressure Limits

This valve carries a Class 150 rating with a maximum operating pressure of 300 psi for water, oil, and gas media. Steam service is limited to a maximum pressure of 150 psi, making it unsuitable for high-pressure steam lines exceeding that threshold.

Female NPT Connection

The valve installs via female NPT threads on both ends, requiring matching male NPT pipe fittings for a sealed joint. Builders using flanged, solder, or press-fit connections cannot use this valve without additional adapters.
