Made of Brass: Ensures the metal faucet connectors are strong, durable and scratch resistant. 2-in-1 connectors: the 3/4" BSP metal brass faucet connectors and 1 /2" can be used with all outdoor taps (taps must have a male thread). Easy to use: The tap connector consists of two parts. The connector fits a 1/2" faucet when both pieces are intact. After unscrewing the top, the connector fits into a 3/4" faucet. Compatible: the connector attaches securely to the exterior faucet and converts it into a standard quick-connect system.
