This 12.5mm and 15mm Quick Connect Hozelock AquaStop Fitting is specifically designed for use at the gun end of your hosepipe, making it the ideal choice for connecting spray guns and other watering accessories to smaller diameter hoses. The compact size suits 12.5mm and 15mm (approximately 1/2 inch) hoses perfectly, providing a secure yet flexible connection point.
