Brasscraft bc-b1-30af Lavatory Supply Line 30 in

Product Description

The BRASSCRAFT bc-b1-30af is a braided polymer lavatory supply line designed to connect the shut-off valve to the faucet inlet on a bathroom lavatory. The line measures 30 inches in length and uses a 3/8 inch compression fitting on the valve end and a 1/2 inch female iron pipe (FIP) fitting on the faucet end. The braided polymer construction provides flexibility during installation while resisting kinking and abrasion under the sink. This type of supply line is a standard replacement or new-installation component used by licensed plumbers and experienced DIYers on residential lavatory faucet hookups.

This supply line is suited for residential bathroom lavatory installations where the shut-off valve terminates at a 3/8 inch compression outlet and the faucet inlet requires a 1/2 inch FIP connection. The 30 inch length accommodates typical under-sink cabinet depths and standard rough-in plumbing configurations. It is commonly used when replacing a leaking or aging supply line or completing a new faucet installation.

Key Features

• 30 inch length suits standard residential under-sink lavatory installations
• 3/8 inch compression inlet connects directly to standard shut-off valves
• 1/2 inch FIP outlet threads onto common lavatory faucet inlets
• Braided polymer construction resists kinking, abrasion, and cracking
• Flexible design allows for easy routing in confined cabinet spaces

Compatibility

Designed as an OEM-style replacement supply line for residential lavatory faucet applications requiring a 3/8 inch compression to 1/2 inch FIP connection at 30 inches in length.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer. Shut off the water supply at the angle stop valve and relieve pressure before disconnecting the existing supply line. Hand-tighten fittings first, then snug with an adjustable wrench — avoid overtightening, which can crack compression fittings or strip FIP threads. Verify there are no leaks at both connections after restoring water supply.
