Ts Brass B970FE Dual Check Vacuum Breaker 3/8 Inch Mnpt

Product Description

The TS BRASS B970FE is an inline continuous pressure dual check vacuum breaker with an intermediate vent, designed to prevent backflow and protect potable water supplies at faucet connections. The body is polished chrome plated brass with 3/8 inch MNPT female inlet and outlet connections. It handles a maximum flow of 7.27 GPM, operates within a pressure range of 20 to 125 psi, and is rated for water temperatures from 40 degrees F to 140 degrees F. This device is installed by licensed plumbers in residential and light commercial plumbing systems wherever continuous pressure backflow protection is required at the point of use.

The B970FE is suited for faucet applications where an inline vacuum breaker is required under continuous pressure conditions. Its intermediate vent design allows it to function in installations where the downstream side remains pressurized, making it appropriate for supply connections on commercial faucet assemblies, pre-rinse units, and similar fixtures. The chrome plated finish blends with standard fixture trim in visible installations. This device meets certification requirements for both US and Canadian plumbing codes, making it suitable for cross-border commercial and residential projects.
