Fluidmaster Inc B1T20CS Ss Toilet Connector 20 Inches

Product Description

The FLUIDMASTER INC B1T20CS is a 20-inch braided stainless steel toilet supply connector designed for use in residential and light commercial plumbing installations. It features a 3/8-inch female compression thread inlet and a 7/8-inch female ballcock thread outlet, making it a direct-fit solution for standard toilet fill valve connections. The standout feature is the Click Seal connection system: the nut emits an audible click when the connector has achieved a proper seal, eliminating guesswork and preventing over-tightening. Over-tightening is a leading cause of cracked connector nuts and damaged fill valve shanks, so this built-in feedback mechanism reduces callback risk on toilet installs.

This connector is suited for toilet rough-in applications in residential bathrooms and commercial restrooms where a durable, corrosion-resistant supply line is required. Plumbers and plumbing contractors install this part when connecting the water supply stop valve to the toilet fill valve. The braided stainless steel construction provides resistance to kinking, bursting, and corrosion compared to vinyl or unbraided lines. It is sold individually and packaged in quantities of 15 units per case, making it practical for contractors stocking service vehicles or supply rooms.

Key Features

• Click Seal nut provides audible confirmation of proper seal, preventing over-tightening
• Braided stainless steel construction resists corrosion, kinking, and bursting
• 20-inch length accommodates standard toilet-to-stop-valve rough-in distances
• 3/8-inch female compression x 7/8-inch female ballcock thread ends fit most residential toilet fill valves
• Reduces risk of cracked connector nuts and damaged fill valve shanks during installation

Compatibility

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

Installation Notes

A licensed plumber or qualified tradesperson should install this connector in accordance with the International Plumbing Code (IPC) and local authority requirements. Shut off the water supply at the stop valve and flush the toilet to relieve line pressure before removing the old connector. Hand-tighten the Click Seal nut until the audible click confirms a proper seal — do not apply additional torque beyond the click. Inspect for leaks at both connection points after restoring water supply.
