"I used this, along with other fittings from the FloPlast range, to run a 20mm MDPE pipe up my garden to the greenhouse. This stopcock works well and easily holds my mains water pressure which is very high. The compression fittings are very easy to use - my technique (after fitting the thimble liner to the pipe) was to remove the nut and gripper and slide these onto the pipe, wipe a smear of Vaseline around the end of the pipe and then push firmly into the fitting until it goes through the O-ring. Then slide the gripper down the pipe and tighten the nut. All the connections were leak free first time. Job done!"

Review 4 for FloPlast MDPE Plastic Stop Cock 20mm x 20mm
"I have used four of these over the last few months, three have developed a leak after a few weeks from the spindle shaft. The fourth never leaked because I took it back and changed it for another make."
