3/8 in. I/D. or O.D.

Postby Radler » Tue Jun 27, 2006 5:58 pm

I am trying to build a chiller but I forget if I have heard that the copper tubing should be 3/8 in. diameter on the inside or outside. Or maybe it's not that measurement at all. Anybody want to comment on how much they have payed to make one of these. Thanks.

Copper Tubing

Postby brewmeisterintng » Wed Aug 23, 2006 7:10 am

I don't if it is OD or ID but I think that when you buy copper tubing you get it in 3/8 inch as any larger and you won't get as efficient heat transfer. I cheated and bought mine. In retrospect I should have made it but it was an impulse buy at the LHBS. I think I paid 40 bucks for the phils chiller.
