Jb Industries 3103 Lavatory Supply Tube 3/8 in 20 in

Product Description

The JB INDUSTRIES 3103 is a brushed nickel lavatory supply tube designed to deliver water from a shutoff valve to a bathroom faucet or lavatory fixture. With a 3/8-inch OD connection and a 20-inch length, it fits standard residential lavatory installations where a clean, corrosion-resistant line is required. The brushed nickel finish complements common faucet finishes and holds up to the moisture-heavy environment under a bathroom vanity. Licensed plumbers and experienced DIYers install this tube as part of new faucet installs or supply line replacements.

This supply tube is suited for residential bathroom lavatory applications. It connects a standard 3/8-inch OD shutoff valve outlet to a faucet inlet, covering the typical under-sink distance found in most vanity cabinets. The 20-inch length provides enough reach for standard vanity depths without excessive slack. It is appropriate for cold or hot water supply lines serving lavatory faucets.

Key Features

• 3/8-inch OD diameter matches standard residential shutoff valve outlets
• 20-inch length covers typical under-sink lavatory installations

Compatibility

Installation Notes

This supply tube is installed by licensed plumbers or qualified tradespeople. Shut off the water supply at the main valve or the local angle stop before removing the existing supply line. Hand-tighten the compression or nut fittings first, then snug with a wrench — avoid overtightening, which can crack fittings or deform the tube. Verify there are no leaks at both the shutoff valve end and the faucet inlet end before returning the system to service.
