Brasscraft bc-b3-20af Lavatory Supply Line 20in

Product Description

The BRASSCRAFT bc-b3-20af is a braided polymer lavatory supply line designed to connect the shutoff valve to the faucet inlet on bathroom lavatory installations. The line measures 20 inches in length and uses a 1/2 inch compression fitting on one end and a 1/2 inch female iron pipe (FIP) fitting on the other. The braided polymer construction resists kinking and provides flexible routing in tight under-sink cabinet spaces. Licensed plumbers and experienced DIYers install this type of supply line as a standard part of faucet replacement or new lavatory rough-in work.

This supply line is suited for residential bathroom lavatory applications where a flexible connector is needed between an angle stop or straight stop shutoff valve and the faucet supply inlet. The 20-inch length accommodates typical cabinet depths and valve-to-faucet distances found in standard vanity installations. The compression-by-FIP configuration matches common domestic faucet and valve fitting combinations.

Key Features

• 20-inch length provides flexible reach in standard under-sink installations
• 1/2 inch compression inlet connects directly to angle or straight stop shutoff valves
• 1/2 inch FIP outlet threads onto standard faucet supply shanks
• Braided polymer construction resists kinking and abrasion
• Flexible design simplifies routing in confined cabinet spaces

Compatibility

Designed as an OEM-style replacement or new-installation supply line for residential bathroom lavatory faucets requiring a 1/2 inch compression inlet and 1/2 inch FIP outlet connection.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply at the angle stop or straight stop valve before disconnecting any existing supply line. Hand-tighten the compression fitting onto the valve and the FIP end onto the faucet shank, then snug with an appropriately sized wrench — do not over-torque polymer fittings. After installation, slowly restore water supply and inspect both ends for leaks before closing the cabinet.
