Brass male and female inserts are crucial components for connecting PPR (Polypropylene Random) pipes to threaded fittings or fixtures. They consist of a brass body with either male or female threads on one end and a spigot end designed to be heat-fused into the PPR pipe. These inserts provide a strong, leak-proof, and durable connection, bridging the gap between plastic and metal components in plumbing systems. They are commonly used for transitions to valves, faucets, or other threaded connections in PPR piping networks.
