741-356 is a Bismar brass tee fitting designed for compatible propane and gas-line applications. It features three 3/8" connections, with two male flare (MFL) connections and one male pipe thread (MPT) connection. This tee configuration allows three compatible lines or fittings to be connected at a common junction. Verify the flare and pipe-thread specifications of the existing installation before replacement to ensure proper fit and compatibility.
