Water also works well -- cut the tubing a couple inches longer and sweat a
cap on one and a ball valve on the other.

For small stuff, you can use Woods Metal, Bending Alloy or Bismuth. Bismuth
is being sold for use as shotgun shot (the enviro weenies are complaining
about introducing lead into the environment).

Woods Metal melts below the boiling point of water and is relatively
non-toxic.
