The BRASSCRAFT str37x c is a nonpotable water angle stop valve designed for shutoff service in plumbing supply lines. This valve connects a 1/2-inch female pipe thread (FPT) inlet to a 1/2-inch outer diameter (OD) compression outlet, making it a standard configuration for under-sink or in-wall applications. The angle stop design allows the supply line to change direction 90 degrees from the wall stub-out to the fixture connection. A loose key (LS) operated handle controls flow, which is a common requirement in commercial or restricted-access installations where tool-operated shutoff is preferred. This fitting is rated for nonpotable water service only.
This angle stop valve is typically installed in nonpotable water supply systems such as irrigation stub-outs, process water lines, or similar applications where the water is not intended for human consumption. The 1/2-inch FPT inlet threads directly onto a standard male-threaded wall stub-out, while the 1/2-inch OD compression outlet accepts standard copper or compatible supply tubing. It is installed by licensed plumbers or qualified mechanical contractors during rough-in or service work.
Designed as an OEM-style replacement or new-installation angle stop for nonpotable plumbing supply systems using 1/2-inch FPT wall connections and 1/2-inch OD compression supply lines.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the upstream water supply and relieve line pressure before removing any existing valve or making new connections. Apply thread sealant tape to all male pipe threads before assembly. Do not use this valve on potable water supply lines.
