3/8" x 7/8" x 20" Braided Flexible Water Supply Connector, Lead-Free

Fluidmaster PRO1T20 Braided Toilet Connector – 3/8" Compression x 7/8" Ballcock, 20" Length

The Fluidmaster PRO1T20 is a 20-inch flexible supply line engineered for connecting a 3/8" compression outlet to a standard 7/8" ballcock toilet fill valve. Designed for residential and light commercial toilet installations, this connector features a reinforced PVC core and a polymer-braided exterior for strength, flexibility, and resistance to deformation during installation.

The PRO Series is designed with high-performance tolerances and components suitable for professional-grade work. The coupling nuts are constructed from polypropylene for chemical resistance and include integrated rubber washers to maintain a watertight seal at critical connection points.
