15mm x Â½" Straight Service Valve
So long as you heed the earlier comment to hand tighten the exit - appliance side - of the valve with an allen key in the end, there's no reason for this to leak. Fitted in seconds, working fine.

Good but one tip..
Before you start get an Allen key and tighten the female end. Bought two of these and both of them leaked. Had to disconnect and tighten them up. Worked fine after that.

Does about the job, but still pearling drop of water one every other time!

This product is likely to come apart when first used. After reading previous reviews, I checked the insert was suitably tightened, however, by the time I nipped it up it had managed to loosen itself. The first time you notice this is when you open the valve and spray water all over the room. Clearly there is a manufacturing/assembly issue with this product. There is an alternative Conex available from Screwfix, but unfortunately it is shorter and not a direct replacement.
