Eastman 12 Inch Flexible Toilet Connector, 7/8 Inch Ballcock x 3/8 Inch

The Eastman 12-inch flexible toilet connector links your bathroom water supply to the toilet tank. Designed for quick hookups, it features standard 7/8-inch ballcock and 3/8-inch compression fittings. This makes it a practical solution for homeowners and plumbers replacing old, rigid water lines or updating bathroom fixtures.

Durability comes from a multi-layer design. The line is built around a flexible PVC core surrounded by multi-filament braided nylon, a clear vinyl outer shell, and a grade 304 braided stainless steel jacket. This layering ensures the hose resists kinking and crimping while maintaining steady water flow under pressure.

Installation is straightforward thanks to full-flow brass barbs and nickel-plated solid brass hex nuts. You do not need glue, solder, or special crimping tools to secure the line in place. It operates at standard working pressures up to 125 PSI and handles continuous temperatures from 40 to 150 degrees Fahrenheit, with a maximum burst rating of 2500 PSI.

Keep in mind that at 12 inches in length, this hose requires the water shut-off valve to be relatively close to the toilet tank inlet. Additionally, the manufacturer specifies this lead-free connector specifically for non-potable water plumbing setups.

Verdict: The Eastman 12-inch flexible connector is a dependable, easy-to-install choice for anyone replacing a standard toilet supply line. If your plumbing setup matches the 7/8-inch ballcock to 3/8-inch compression configuration, this durable braided line provides a secure fit.
