Hozelock Pro Metal Hose End Connector with scratch-resistant zinc die-cast sleeve and anti-kink flexible hose tail. Thanks to a triple locking system, the connection to the tap is guaranteed secure up to 10 bar - which is ten times more pressure than the water companies are required by statute to deliver to a residential property. Suitable for use with all 12.5mm 1/2\" and 15mm 5/8ths\" hose. All internal parts are made from ultra tough engineering plastics for a long leak free life.
