Brasscraft b1-12dlmbf Braided Toilet Supply Connector

Product Description

The BRASSCRAFT b1-12dlmbf is a 12-inch flexible braided polymer toilet water supply connector with a 3/8-inch compression inlet and a 7/8-inch ballcock nut outlet. Designed for potable water distribution systems, it features multi-filament polymer-coated fibers that resist corrosion inside and out. The inner PVC tubing withstands chlorine, chloramines, and other common corrosive agents found in municipal water supplies. Plated brass nuts provide durable, long-lasting connections at both ends. This connector is installed by plumbers and qualified tradespeople during toilet supply line service or new fixture installation.

This connector is suited for residential toilet supply line applications in accessible indoor locations. The 7/8-inch ballcock nut outlet connects directly to a standard toilet ballcock inlet using a hand-tighten wing nut, eliminating the need for tools at that end. The 3/8-inch compression fitting connects to a standard angle stop or straight stop valve. The matte black finish makes it compatible with installations where matching fixture hardware aesthetics is a requirement.

Installation Notes

This connector is installed by licensed plumbers or qualified tradespeople. Shut off the water supply at the stop valve and flush the toilet to relieve line pressure before disconnecting the existing supply line. Hand-tighten the ballcock nut onto the toilet inlet, then use an appropriate wrench to snug the compression fitting at the stop valve — do not overtighten. This connector is rated for indoor, accessible locations only and is not intended for concealed or in-wall installations.
