Brasscraft bc-b3-12dlf Braided Polymer Closet Supply Line

Product Description

The BRASSCRAFT bc-b3-12dlf is a 12-inch braided polymer closet supply line designed to connect a water supply stop valve to a toilet fill valve. It features a 1/2-inch compression inlet and a 7/8-inch compression outlet, making it a direct-fit solution for standard residential toilet installations. The braided polymer construction provides flexible routing in tight spaces while resisting kinking and corrosion. Plumbers and experienced DIYers install this line during toilet replacements, rough-in work, and supply valve changeouts.

This supply line is suited for residential bathroom applications where a flexible, corrosion-resistant connection is needed between the angle stop and the toilet tank. The 12-inch length accommodates typical wall-to-toilet tank distances found in standard residential rough-in configurations. It is a common stock item for plumbing service calls and new construction bathroom trim-out work.

Key Features

• 12-inch length for standard residential toilet supply connections
• 1/2-inch compression inlet fits common angle stop valves
• 7/8-inch compression outlet fits standard toilet fill valve shanks
• Braided polymer construction resists kinking and corrosion
• Flexible body allows easy routing in confined cabinet and wall spaces

Compatibility

Designed as an OEM-style replacement supply line for standard residential toilet installations using a 1/2-inch compression angle stop and a 7/8-inch compression toilet fill valve inlet.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply at the angle stop or main shutoff before removing the old supply line. Hand-tighten the compression fittings first, then snug with an adjustable wrench — do not overtighten, as polymer fittings can crack under excessive force. Inspect both connection points for leaks after restoring water pressure.
