Brasscraft bc-b3-20dlf Braided Closet Supply Line

Product Description

The BRASSCRAFT bc-b3-20dlf is a 20-inch braided polymer closet supply line designed to connect the water supply stop valve to a toilet ballcock or fill valve. It features a 1/2-inch compression inlet fitting and a 7/8-inch ballcock nut outlet, covering the most common residential toilet rough-in configuration. The braided polymer construction provides flexibility during installation and resistance to kinking. Licensed plumbers and experienced DIYers install this line as part of toilet replacement, stop valve service, or routine supply line maintenance.

This supply line is suited for residential toilet installations where a flexible, pre-terminated connector is required between the angle stop and the toilet fill valve. The 20-inch length accommodates standard wall-to-toilet distances found in typical residential bathrooms. The compression x ballcock end configuration eliminates the need for additional adapters in most standard installations.

Key Features

• 20-inch length fits standard residential toilet rough-in applications
• 1/2-inch compression inlet connects directly to angle or straight stop valves
• 7/8-inch ballcock nut outlet fits most residential toilet fill valves
• Braided polymer construction resists kinking and provides installation flexibility
• Pre-terminated ends reduce installation time

Compatibility

Designed as an OEM-style replacement supply line for residential toilet installations requiring a 1/2-inch compression inlet and 7/8-inch ballcock outlet connection.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer. Shut off the water supply at the angle or straight stop valve and flush the toilet to relieve line pressure before disconnecting the existing supply line. Hand-tighten the compression fitting and ballcock nut, then snug with a wrench — do not overtighten braided polymer fittings, as excess torque can crack the nuts. Verify for leaks by slowly reopening the stop valve and inspecting both connections.
