Can anyone tell me the size of the unions in the pic or a methods how to check the sizes?

Thanks

There is a list of spanner sizes used for different size unions somewhere on the web, probably in the goodridge catalog.

You could always remove the unions and check the thread size.

look like -6 to me.

-06 has an I.D of 8.7mm & has 9/16 x 18 thread (ie 9/16 is the O.D of the thread)

-08 has an I.D of 11.1mm & has 3/4 x 16 thread

HTH - I don't stock these unions/hoses but can get them in - I believe cheaper than you'll get them anywhere else
