I am looking at Samco Silicone hoses. I just want to know..The dimensions on your site, are they the INTERNAL or EXTERNAL size of the bore?
These sizes are the internal dimensions of the Samco Silicone hoses, and on the Merlin ally hose joiners the sizes are the OD, so you just need both sizes to be the same.
