The Hozelock Pro Metal Hose Connector has a zinc die-cast sleeve which ensures it is strong, durable, and scratch resistant. All internal parts are made from ultra-tough engineering plastics for a long, leak free life. The connection to the tap is guaranteed secure up to 10 bars, thanks to a triple locking system. The Hozelock sleeve is easy to use even when wet because of the twin soft touch pads. While the hose is securely connected by barbs connecting with the inside, and outside, of the hose. Hose kinking, hose swelling and hose leaking, at the connection point with the fitting, are virtually eliminated due to the ingenious flexible hose-tail on the nut. This connector is best used at the tap end of the hosepipe. Suitable for use with all 12.5mm (1/2in) and 15mm (5/8in) hose diameters.
