Connect Beer tailpiece (barb + hex) to 90 degree elbow tailpiece

The part to buy
A straight tailpiece and a 90 degree elbow tailpiece do the same job, turning a shank or coupler thread into a barb, but you fit one or the other by the room behind the faucet, not both. The elbow bends the line to save depth.
Choose the elbow when a straight tailpiece would foul a wall or a neighbouring keg, and the straight one when there is depth to spare. Both seal the same way, a washer at the shank and a clamp at the barb.
