The FLUIDMASTER INC B1F16 is a 16-inch braided stainless steel faucet supply connector designed to link a shut-off valve to a faucet body in residential and light commercial plumbing applications. The connector features a 3/8-inch female compression thread on one end and a 1/2-inch iron pipe size (IPS) female straight thread on the other, covering one of the most common faucet hookup configurations. The braided stainless steel construction provides flexibility during installation while resisting corrosion and handling normal supply line pressure. Plumbers and experienced DIYers install this connector as part of faucet replacement, lavatory rough-in, or fixture upgrade work.
This connector is suited for under-sink faucet supply connections in bathrooms and kitchens where a 3/8-inch compression valve outlet meets a 1/2-inch IPS faucet inlet. The 16-inch length accommodates standard cabinet depths and provides enough slack for straightforward routing without kinking. It is sold in packages of 25 units, making it practical for plumbing contractors stocking for multiple fixture installs or service calls.
Designed as an OEM-style replacement and standard supply connector for faucets requiring a 3/8-inch female compression inlet and a 1/2-inch IPS female straight thread outlet, typical of residential lavatory and kitchen faucet installations.
Installation is performed by a licensed plumber or qualified tradesperson in accordance with local plumbing codes and IPC guidelines. Shut off the water supply at the stop valve and relieve line pressure before removing the existing connector. Hand-tighten the compression fitting first, then snug with a wrench — avoid overtightening, which can crack the compression nut or damage the valve seat. Inspect both end connections for drips after restoring supply pressure.
