Description
The WATTS BRASS TUBULAR PL-3042 is a quick connect straight valve designed for use with 3/8-inch outside diameter poly or soft copper tubing. One end accepts a push-in quick connect fitting for fast, tool-free tube insertion, while the other end terminates in a 3/8-inch male pipe thread (MPT) for standard threaded connection. This valve is intended for low-pressure water supply applications where a reliable shutoff point is needed. It is sold in a pack of 5 units, making it practical for multi-fixture installs or service stock. Licensed plumbers and pipefitters are the typical installers for this type of valve in residential and light commercial settings.
This valve suits applications where flexible poly tubing or soft copper runs are connected to a threaded port, such as ice maker supply lines, water filtration systems, and similar low-pressure service lines. It is not rated for use with steel tubing and must not be used in concealed installations where access for inspection or servicing is restricted. The quick connect end simplifies connections in tight spaces without the need for compression fittings or flare tools.
