Next question...do you use females on the kettle and tun and males on the hoses, or vice versa? Edumacate me!I put male ends on kettles since the female side contains a rubber gasket and the cam levers that you must squeeze with your hand to lock it. I want both of those away from the flame.
I have it the other way and put male ends on the hoses and females on the BK and HLT respectively.
Why? I guess I went with anatomical logic. Hose = male. Put male ends on the hoses!
Really I didn't think about it more intently but your answer makes more sense.
That said, I haven't had a problem getting burned on the camlocks yet, but it probably depends on your burner stands and vessels. I can see it being an issue with a flat bottom pot like my HLT since the ball valve is so low but it still hasn't happened for me. It's way out there on the end of my ball valve.
My BK is a keggle so it doesn't get hot enough to bother me and never sees flamage.
Most of the high heat through the camlocks for me has been when handling them after sparging because I switch one of my hoses connected to the pump from the HLT to the BK to recirculate and sometimes I do that too soon after sparge is done. Don't need to but have done it and they are hot enough to be noticeable, that's for sure.
