You need to tell us more...
Most plumbing outlets stock converters... For instance: Compression Male Iron Coupler 15mm x 3/4 Inch Compression Male Iron Coupler 15mm x 1/2 Inch Compression Male Iron Coupler 22mm x 3/4 Inch Compression Male Iron Coupler 22mm x 1 Inch Compression Male Iron Coupler 35mm x 1 1/4 Inch Once you have done the conversion, then it's normal (IMHO) to use metric.

I'll try and post a picture....could take some time but basically with this fitting being so old and threaded it doesn't seem to be compatible with anything off the shelf as it has a very fine thread.
in essence tho you're right need to somehow convert to metric size and then use |

it is plumbing related. its the domestic hot water circuit. it would appear the smallest is 10mm bsp.
the other two are a finer unknown thread of 22 and 35mm dia. ?? could also do with finding a way of getting from above sizes to modern equivalents?? |

I take it the threaded part you need to join to is on an appliance so no way of cutting it out and putting a more common fitting on the pipe. Failing that there is allways the option of brazing a common thread onto the obselete end.

yobbie,
you got me there? I'm sure the guy at BSS said the small hole was 10mm BSP....? any how got a plug for this now which will help towards a temporary solution. the other two (the main connections) are a finer thread and I'm guessing the solution might be brazing a new fitting into place? thank you. |
