Re: Really confused. Bloody threads/fittings

Ed - the dash-6, 8 10, etc thread are very different from anything else. They were invented for hydraulic couplings on helicopters!

So - if you have a cooler that has a "dash" size fitting, you need the same on the pipes, and all the measuring in the world won't help.

The "dash" fittings refer to the ID of the pipes, a -12 is 3/4", -16 is 1" etc.

Every size up in 4s is another 1/4" pipe ID.

For help, look up "think auto" - Mocal suppliers, they will sort you out.
