    Metric copper pipe and olives

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I am looking for a place that sells the metric copper pipe and compression olives so that i can redo some of the plumbing in my La Dorio. I went to Enzed and they told me they didnt stock metric fittings and couldnt tell me anyone who did. So does anyone out there have any leads for 10mm and 6mm pipe and fittings?
    Also my olives are a kind I havent seen before, Im more familiar with the mushroom head type ones, not sure if there are a variety of shapes that do the same job, or if I need these exact ones. Maybe someone out there with experience can tell me?

    Re: Metric copper pipe and olives

    May be incorrect but I have found after a year of searching that metric and BSP are the same. I have purchased Metric 10, 6 and 3 mm fittings and they fit what I though was BSP 3 /8, 1/4 and 1/8 BSP. Some of the fittings had both names. I would guess that piping may be the same. My local hardware had basic fitting.

    I dont quite understand this as I dont know what the size relates to - may be the pipe size.

    Re: Metric copper pipe and olives

    The part that worries me is that the threads on the boiler are all metric, so i need the metric nuts to hold it all in place so there may be some incompatibility with the OD of the pipe and the nut.
    I have searched around the web and have found metric fittings and pipe, but the only olives they have are not like the ones currently on the machine, they are the same as ones on other machines I have worked on. So i was wondering, does any 10mm olive seal a compression fitting or do i need these exact ones? The other ones are pictured below

    I would suggest that the original picture is not an "olive".
    It is a fitting where the collar it tightened between two faces. There are a number of HWS pipes that have a ring that is somehow made in the original pipe this increased diameter ring is tightened between two faces. The modified pipe look just like the end of you first picture only the pipe diameter is the same both sides of the ring. It is possible that your pipe end is a part that is made like it is so it can accommodate a smaller pipe. My boiler is Italian and as far as I know they use "metric" pipe threads which are BSP. I would actually physically check your threads.

    the guy at Enzed, said the existing fitting in the first pic is a type of olive that is crimped onto the pipe rather than being silver soldered. The pipe is just regular pipe there are no special collars or anything.

    Re: Metric copper pipe and olives

    still no real luck with this. I called Reece today and was told that they had Metric pipe and fittings but after some more questioning found that they had 3/8 and 1/4 inch pipe and fittings. I was then told that they should work anyway. I guess the only solution to this is going to be to take everything into reece and see what fits.
    Ill post my findings here when i do.

    The compression olives i normally use look like this;
    Try local pump and filter shops for olives, my local one in NZ has them in both metric and bsp.For pipe try local air conditioning or refrigeration specialists.
    The second type of compression fitting shown above is usually soldered to pipe
