UK fittings on Irish pipes

    Please help! Can I use a 28mm compression fitting with a 28mm olive on Irish 1" copper pipe please? Or a 28mm fitting and nut with an Irish 1" olive? Failing that, would a 28mm fitting with the Irish 1" olive and nut work as the threads are 1" BSP?

    Thanks in advance for any advice!

    1. No - the 28mm olive is too large for the Irish 1” pipe and won’t work correctly.
    2. Would be much better, and will work albeit the joint may not be just as durable as it could be.
    3. I don’t understand what you are suggesting here? 1” BSP threads are different to the threads on compression regardless of whether you are dealing in metric or Irish.

    What is it you are trying to do?

    It is ironic that in the south of Ireland we use Imperial

    and in the North and Britain they use Metric.

    Going to be a hassle when they go Metric

    We use ‘Irish’ .

    Imperial pipe sizes were used in the UK pre 1970 and were a different affair again.

    The current UK metric sizing is starting to creep in here though too.

    I'm surprised that the EU doesn't standardise plumbing fixtures. It seems very strange that a market the size of Ireland has a unique approach to something as simple as water piping.
