Brasscraft 1-20DLC1 Copper Toilet Supply Riser 3/8 in Od

Product Description

The BRASSCRAFT 1-20DLC1 is a copper toilet supply riser designed to connect a shut-off valve to a toilet tank fill valve. The riser measures 3/8 inch OD and 20 inches in length and includes a gasket nosepiece for a reliable, leak-resistant connection. Constructed from copper tubing, it provides durable, corrosion-resistant performance in residential bathroom plumbing applications. Licensed plumbers and experienced DIYers install this type of riser as part of toilet rough-in or fixture replacement work.

This riser is used in residential bathroom installations where a flexible or rigid supply line runs from a compression angle stop or straight stop valve up to the fill valve at the base of the toilet tank. The 3/8 inch OD sizing is standard for residential toilet supply connections. The included gasket nosepiece seats against the fill valve inlet to create a watertight seal without the need for additional sealing materials at that connection point.

Key Features

• 3/8 inch OD copper construction for durable, corrosion-resistant performance
• 20 inch length suits standard residential toilet rough-in heights
• Includes gasket nosepiece for a secure, leak-resistant fill valve connection
• Designed for toilet tank-to-stop-valve supply line installations

Compatibility

Designed as an OEM-style replacement supply riser for residential toilet installations using a 3/8 inch OD compression stop valve and a standard fill valve inlet.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer. Shut off the water supply at the angle stop or straight stop valve and flush the toilet to relieve pressure before disconnecting any existing supply line. Avoid over-tightening compression fittings, as copper tubing can deform and cause leaks. Local plumbing codes, including IPC guidelines, may govern acceptable materials and connection methods for toilet supply lines.
