Brass Craft Service Parts PSB857 Toilet Supply Line 20 in

Product Description

The BRASS CRAFT SERVICE PARTS PSB857 is a 20-inch toilet water supply line designed to connect a shutoff valve to a toilet fill valve in residential and light commercial plumbing installations. It uses a 3/8-inch compression fitting on the supply end and a 7/8-inch fitting on the fill valve end. The flexible braided construction uses an engineered polymer braid, providing durability and resistance to kinking. Licensed plumbers and experienced DIYers install this line as a direct replacement during toilet rough-in, fill valve replacement, or fixture upgrades. The overall packaged dimensions are 21 inches long by 4 inches wide by 3.5 inches deep.

This supply line is suited for standard toilet installations where the shutoff valve terminates with a 3/8-inch compression outlet and the fill valve accepts a 7/8-inch connection. The 20-inch length accommodates typical wall-to-toilet rough-in distances found in residential bathrooms. It ships in bulk packaging with a flag label, making it well suited for plumbing supply houses and contractors stocking multiple units. The package quantity is 10 units per pack.

Installation Notes

Installation is performed by a licensed plumber or qualified technician following local plumbing codes and IPC guidelines. Shut off the water supply at the angle stop valve and flush the toilet to depressurize the line before removing the old supply line. Hand-tighten the compression fitting first, then snug with an adjustable wrench — do not overtighten, as this can crack the fitting or damage the valve seat. Inspect both connection points for leaks after restoring water pressure.
