The FLUIDMASTER b1t16 is a braided stainless steel toilet supply connector designed to replace or upgrade an existing toilet water supply line. The connector measures 16 inches in length and uses a 3/8-inch compression inlet fitting on one end and a 7/8-inch ballcock fitting on the other. The polymer core is wrapped in braided stainless steel wire for durability and kink resistance. Nickel-plated brass hex nuts provide a secure, easy-to-grip connection. Crimped stainless ferrules at each end add extra holding strength. This connector is lead-free and is built to meet code requirements for flexible water connectors. Licensed plumbers and experienced DIYers typically handle this installation.
The b1t16 is suited for residential toilet installations where the supply stop has a 3/8-inch compression outlet and the fill valve uses a 7/8-inch ballcock nut. The 16-inch length works in standard rough-in situations where the supply stop is positioned close to the base of the toilet tank. The flexible construction allows the line to route around obstructions in tight spaces without kinking or creasing, reducing installation time. It carries a 5-year warranty from the manufacturer.
Designed as a direct-fit replacement for toilet supply lines using a 3/8-inch compression stop outlet and a 7/8-inch ballcock inlet on the fill valve. Suitable for residential toilet and closet applications.
Shut off the water supply at the angle stop or main valve before removing the existing supply line. Drain residual water from the line before disconnecting. Hand-tighten the ballcock nut first, then snug the compression nut at the stop with an adjustable wrench — avoid over-tightening, which can crack the nut or damage the ferrule seat. Check both ends for leaks after restoring water supply. This work falls under standard plumbing service; local code requirements under the IPC or applicable jurisdiction may apply.
