Hey guys,
I need a 1/4in compression fitting that fitted 1/4in brass/copper pipe, ok.... 1/4in is 8mm..
Therefore does 1/4in pipe have an I.D of 6mm? or do I have everything really mixed up?

well if the o.d is 8mm then the i.d should be around 6mm.

Nominal pipe sizes may or may not be close to an actual dimension of the pipe.
In L type copper tubing, 1/4" tubing is .375" OD (3/8"), and .315" ID. So the ID really is 8mm (actually 8.001mm). That assumes you have 0.035" walls. IIRC, the 1/4" pipe you get at the hardware store is the ".375" OD, .315" ID" stuff.
Mcmaster.com is a good place to look up things like pipe IDs, ODs, pressure ratings...
