    .

    Most wholesalers in the UK will either stock that
    equipment or be able to source it, have you asked any
    of the large wholesalers?

    Regards

    Rob, hard to find components for more than 60 bar. Where can you find a dryer, sightglass for these pressures?
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

    It's quite common in the UK because the supermarkets are using C02.

    You will find that common fittings (sight glasses excluded) are rated well
    above what C02 runs at and all it takes is a re-issue of an insurance test
    certificate.

    It is surprising just how high fittings are tested to prove them safe,
    it is a lot higher than the X 1.43 that it states in the EN378 standards.

    Regards
