The FLUIDMASTER INC B1T16 is a 16-inch braided stainless steel toilet supply connector designed to link a shutoff valve to a toilet tank fill valve. It terminates with a 3/8-inch female compression thread on the supply-valve end and a 7/8-inch female ballcock thread on the toilet end. The braided stainless steel construction resists corrosion and provides durability in the wet, confined conditions typical of toilet rough-in spaces. Plumbers and plumbing contractors install this connector during new construction, remodel work, or routine fixture replacement where a reliable, code-acceptable supply line is required.
This connector is suited for residential and light commercial toilet installations. It fits standard toilet tank inlets and compression-style shutoff valves commonly found in residential bathroom rough-ins. The 16-inch length accommodates typical wall-to-toilet offset distances and provides enough flexibility to align with the ballcock inlet without stressing the fitting connections. Units are packaged 25 per case, making this connector practical for multi-unit or high-volume service work.
Designed as an OEM-style replacement supply line for residential toilet installations requiring a 3/8-inch female compression inlet and a 7/8-inch female ballcock outlet connection.
Installation is performed by a licensed plumber or qualified plumbing technician. Shut off the water supply at the angle stop before removing the existing connector or servicing the fill valve. Hand-tighten the compression fitting first, then snug with a wrench — avoid over-tightening, which can crack the compression seat or damage plastic ballcock threads. After installation, slowly restore water supply and inspect both ends for leaks before closing the access area.
