UKDD® 15 mm x 1/2' mannelijke platte schroefdraad isolatiebal o fix kleppen met zwarte hendel recht voor 1/2' flexibele kraanconnector (paar)

Works perfect easy install

The metal operating handle is great, I have has plastic ones go brittle. It was easy to fit on my original nut and fitted olive as I had to replace the stock screwdriver isolating valve that started to leak water from the screw adjuster after fitting a new toilet filler valve. It did not leak at all re-using the original nut and olive, a great bonus (though i guess i was lucky!) The 1/2 inch thread for a flexible pipe was perfect, no leaks after fitting so happy. Price is OK, there are cheaper ones out there however, for me the metal and durable operating handle is a bonus.

Just what I needed to isolate a basin and the taps are easier than using screws!
