    Is there anyway of fixing a slight leak on an mdpe compression plastic fitting in a similar way to when you wrap ptfe around an olive on copper compression fittings. I guess there's isn't as its an oring seal. Thanks.

    Is it a Plasson or Philmac?

    Plasson are really push fit and the nut stops the water pressure pushing the pipe out. They can show a slight leak if the pipe is scratched or scuffed.

    Philmacs are a compression fitting and would seal on a scratched of scuffed pipe once tightened.

    If you can see the scratch you can usually rub it off with a Stanley blade.

    If you can’t do that you would have to cut back to clean pipe or swap it out for a Philmac.
