The FLUIDMASTER INC B1F12 is a 12-inch braided stainless steel faucet supply connector designed to deliver a reliable, flexible water supply connection between a shut-off valve and a faucet body. It features a 3/8-inch female compression thread on one end and a 1/2-inch iron pipe female straight thread on the other. The braided stainless steel construction resists corrosion and handles the pressure cycling common in residential and light commercial plumbing. Plumbers and fixture installers reach for this connector when replacing faucets, lavatories, and kitchen sinks where a durable, code-acceptable supply line is required.
This connector is suited for residential and light commercial faucet installations, including kitchen faucets, bathroom lavatory faucets, and similar fixtures connected to 3/8-inch compression angle stops or straight stops. The 12-inch length accommodates standard rough-in depths typical in vanity and sink cabinet installations. It ships in a package quantity of 25 units, making it a practical stock item for plumbing contractors, service trucks, and supply houses.
Designed as a direct-fit supply connector for residential and light commercial faucets using a 3/8-inch female compression inlet and a 1/2-inch iron pipe female straight thread outlet. Verify stop valve and faucet shank thread specifications before installation.
Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply at the stop valve and relieve line pressure before disconnecting any existing connector. Hand-tighten the compression nut onto the stop valve first, then snug with an adjustable wrench — do not over-torque, as compression fittings can crack with excessive force. Inspect both end connections for leaks after restoring water pressure. Local plumbing codes, including the IPC, may govern approved connector types for potable water supply lines.
