Awful product did not work 10mm side
Even though the area I had to work in was tight these were small enough to do the job. Only issue was I had to dismantle the 10mm end due to using 10mm plastic piping. The metal clamp ring inside the fitting was so tight I couldn’t push the pipe fully in. Assembled it on the end of the pipe manually then screwed it up tight. Sealed perfectly so would definitely use these again.
This bugs me but Toolstation sometimes give you good fittings and sometimes they give you this pattern. This type require far too much force to insert the pipe. I will avoid them in future.
