Brasscraft bc-b3-30af Lavatory Supply Line 30 in

Product Description

The BRASSCRAFT bc-b3-30af is a 30-inch braided polymer lavatory supply line designed to connect the shutoff valve to a lavatory faucet in residential and light commercial plumbing installations. The line features a 1/2-inch compression inlet fitting on one end and a 1/2-inch female iron pipe (FIP) outlet on the other, making it a direct-connect solution for standard lavatory rough-in configurations. The braided polymer construction provides flexible routing and resistance to kinking during installation. Licensed plumbers and experienced DIYers install this type of supply line as part of faucet replacements, vanity installations, and fixture rough-in work.

This supply line is suited for lavatory sink installations in residential bathrooms and powder rooms, as well as light commercial restroom applications. The 30-inch length accommodates standard vanity cabinet depths and typical shutoff valve placement. The 1/2-inch compression by 1/2-inch FIP fitting configuration matches common shutoff valve outlets and faucet supply inlets found in standard North American plumbing installations.

Key Features

• 30-inch length for flexible routing in standard lavatory installations
• 1/2-inch compression inlet fits standard angle stop shutoff valves
• 1/2-inch FIP outlet connects directly to most lavatory faucet supply shanks
• Braided polymer construction resists kinking and allows flexible positioning

Compatibility

Designed as an OEM-style replacement supply line for standard residential and light commercial lavatory faucet installations using 1/2-inch compression shutoff valves and 1/2-inch FIP faucet inlets.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply at the angle stop or main shutoff before removing the existing supply line. Hand-tighten fittings first, then snug with an appropriately sized wrench — do not overtighten, as polymer-bodied fittings can be damaged by excessive torque. Inspect all connections for leaks after restoring water pressure.
