The BRASSCRAFT 1-12DLC is a 12-inch chrome-plated copper toilet supply riser designed for connecting a shut-off valve to a toilet tank fill valve. It features a 3/8-inch OD tube construction with a heavy-duty rubber nosepiece that creates a secure, leak-resistant seal at the tank connection. The chrome finish provides corrosion resistance suited to the exposed plumbing environment beneath a toilet tank. This riser is a standard component in toilet rough-in and replacement work performed by licensed plumbers and experienced DIYers.
This supply riser is used in residential bathroom plumbing installations where a rigid copper riser is preferred over a braided or corrugated flexible line. It is appropriate for new toilet installations, toilet replacements, or supply line upgrades where the existing line shows wear or corrosion. The 12-inch length suits standard rough-in configurations where the shut-off valve sits close to the floor and the toilet tank is within typical reach.
Designed as an OEM-style replacement supply riser for residential toilet installations requiring a 3/8-inch OD rigid copper supply line with a 12-inch length.
Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply at the angle stop valve and flush the toilet to relieve line pressure before removing the existing supply line. Hand-tighten the nosepiece connection at the tank fill valve inlet, then snug with pliers — avoid over-tightening, which can crack the fill valve shank. Follow applicable IPC and local plumbing code requirements for supply line materials and connections.
