The BSC PREFERRED 496-104DIB is a flexible braided stainless steel toilet supply line designed to connect the shutoff valve to the toilet fill valve in residential and commercial installations. The line features an inner PVC core reinforced with braided stainless steel strands, providing kink resistance and protection in exposed under-tank locations. Connections measure 3/8 inch compression on the supply valve end and 7/8 inch ballcock on the toilet end. At 16 inches in length, this line suits standard rough-in installations without excess slack.
This supply line is suited for both residential and light commercial toilet installations. The braided stainless steel exterior handles the physical demands of exposed plumbing in bathroom cabinets and open rough-in settings. The compression-to-ballcock configuration is a widely used connection pairing for gravity-fed tank toilets, making this line a common replacement or new-installation component for plumbers and maintenance technicians.
Designed as an OEM-style replacement supply line for residential and commercial gravity-tank toilets using a 3/8 inch compression shutoff valve and a 7/8 inch ballcock fill valve connection.
A licensed plumber or qualified technician should install this supply line following applicable IPC requirements. Shut off the water supply at the angle stop valve and flush the toilet to relieve line pressure before disconnecting the existing line. Hand-tighten the compression fitting and ballcock nut, then snug with an adjustable wrench — do not overtighten the PVC-core fittings. Inspect for leaks at both connections after restoring water supply.
