    I want to insulate 20mm o.d. copper pipes with that split foam stuff and want a snug fit

    I tired insulation marked 22mm (if marked correctly) from a couple of places (thinking a mm or two extra would be required) but they all flop around on the pipe.

    Is 20mm bore insulation what I need, and where would I get it.

    thanks.

    Are you trying to insulate 3/4" Irish copper?

    Standard irish copper pipe, regarded as 3/4" but in metric o.d measures 20mm.


    conversion calculator says:- 0.75in = 19.050mm

    Just get 3/4 lagging then. If it's a tad loose it won't matter
