John Guest Tap Adapter 1/2″ BSP to Imperial Tube sizes
Choose you tube size from the sales drop down list.
Please note:
The 1/2″ BSP female end configuration on this fitting is designed to screw onto a thin wall thickness thread or valve.
The internal diameter of the male thread must not be no less than 15mm for it to fit correctly into the slot and seat onto the seal.
This means that although needing a 1/2″ one of these for many ice maker or fridge connections. Generally this won’t screw correctly onto your wall tap.
This will then require the purchase of our JG Tap Adapter combo for your Fridge 1/2″ to 1/4″ connection.
Hand tightening is more than sufficient and at no time should tools be used for tightening this fitting.
