This elbow allows for a change of direction when connecting two pipes or fittings with female ends. “Flat seat” means the sealing surface is flat or flat to ensure a secure connection when the accessories are assembled.

Union Elbow F/F Flat Seat is used to join pipes at an angle, providing flexibility and allowing for disassembly when required without disturbing the pipes.
