Fluidmaster Inc B1T09 Ss Toilet Connector 9 Inches

Product Description

The FLUIDMASTER INC B1T09 is a 9-inch braided stainless steel toilet supply connector designed to link the shutoff valve to the toilet fill valve in residential and light commercial plumbing installations. It features a 3/8-inch female compression thread on the valve end and a 7/8-inch female ballcock thread on the toilet end. The braided stainless steel construction resists corrosion and provides flexibility during installation, making it a durable choice for toilet rough-in connections. Licensed plumbers and experienced DIYers install this type of connector as a direct supply line replacement or during new toilet installations.

This connector is suited for standard toilet installations where the distance between the shutoff valve and the ballcock inlet measures approximately 9 inches. It is commonly used in residential bathrooms, apartment builds, and light commercial restroom applications. The compression fitting end accommodates standard 3/8-inch OD compression shutoff valves, while the 7/8-inch ballcock thread end fits most standard toilet fill valves. No specialty tools are required beyond an adjustable wrench for final tightening.

Key Features

• 9-inch length suitable for close-clearance toilet rough-in installations
• Braided stainless steel outer sleeve resists corrosion and kinking
• 3/8-inch female compression thread fits standard shutoff valve outlets
• 7/8-inch female ballcock thread fits most standard toilet fill valves
• Flexible design allows for minor misalignment between valve and toilet inlet

Compatibility

Designed as an OEM-style replacement supply line for residential and light commercial toilet installations using a 3/8-inch compression shutoff valve and a standard 7/8-inch ballcock-threaded fill valve.

Installation Notes

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 pressure before disconnecting any existing supply line. Hand-tighten the connections first, then snug with an adjustable wrench — avoid over-tightening, which can crack the ballcock nut or damage compression ferrules. Inspect for leaks at both ends after restoring water supply.
