Good point Jerry, although that ASTM number corresponds to a tensile yeild strength of at least 25,000 psi. It's normally specified for instrument tubing, used for pneumatic instrumentation or relatively low pressure (~100 psi) liquid service.
For comparison, copper nickel brake tubing is rated for 16-22,000 psi.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
