How good is brass compression fitting in vacuum?
How good is brass compression fitting in vacuum?
(OP)
BACKGROUND
I need to maintain a metal plate at 25 plus minus 0.5 deg C. The plate is 6 x 150 x 600 mm (1/4 x 6 x 24 in). I plan to braze a copper tubing to the place and flow water through the tubing. The setup sits inside a vacuum chamber, 10e-5 torr, not a high vacuum.
QUESTION:
The soft copper tube will be soldered to a brass socket fitting. How tight is brass socket fitting? Good enough to be used in vacuum?
Thanks.

I can't see where a brass fitting wouldn't be equivalent to the Cu tubing being used.
I have pulled some pretty high vacuum on Cu tubing for He leak testing and haven't had any problem with either brass or Cu fittings
