As a commercial Gas / HVAC engineer, my job has to be 100% correct and the material we use has to be perfect for our customers. Using the copper press fit straight coupler from Toolstation are the best I've used and they never leak or the rubber seals never fall out.
All these comments saying they’re no good and slide..YOU NEED TO COMPRESS IT USING A CALIBRATED PRESS GUN NOT JUST SLIDE IT ON THE PIPE THAT IS NOT ITS PURPOSE.. I just don’t want people who does have a press gun to be put off by bad reviews because the coupler is fine for press fit purposes.
Brought these with bends would not recommend these as seem really loose when joining to pipe so got compression in the end
Does not slide into the area will require cutting of pipe
Rubbish joints not good for pressure pipe
Dont buy
These are for a press gun .. Mr DIY should not be buying or using let alone giving a bad review !!
This sliding joint is a complete waste of time and not fit for purpose
