Fluidmaster Inc B1F20CS Faucet Supply Connector 20in

Product Description

The FLUIDMASTER INC B1F20CS is a faucet supply line connector designed for residential and light commercial plumbing installations. It features a 3/8-inch compression inlet and a 1/2-inch female iron pipe (FIP) outlet, with an overall length of 20 inches. The Click Seal design delivers an audible click when the connection is adequately tightened, giving the installer a clear confirmation of proper torque without guesswork. The flexible construction resists kinking and creasing even in confined under-sink spaces, making it well suited for fast, efficient service calls. This connector exceeds applicable code requirements for flexible water connectors.

This supply line connector is intended for use in faucet supply installations in residential bathrooms, kitchens, and utility areas. The 3/8-inch compression-to-1/2-inch FIP configuration is a common fitment for standard faucet supply stubs and shutoff valve outlets. It is typically installed by licensed plumbers or experienced plumbing service technicians during faucet replacement, remodel work, or routine maintenance. The 20-inch length provides enough reach to accommodate typical vanity and kitchen sink cabinet depths without excess slack.

Installation Notes

Installation is performed by a licensed plumber or qualified plumbing technician. Shut off the water supply and relieve line pressure before disconnecting any existing supply line. Hand-tighten the compression fitting first, then continue tightening until the audible click confirms proper seating — do not over-tighten beyond the click confirmation. Verify all connections for leaks after restoring water supply, in accordance with applicable local plumbing codes.
